Can someone help me out on this? Solve using substitution. x - 4y = 4 6x - 3y = -18 Solution Given [x-4y=4;6x-3y=-18] Solve the first equation for [x: x=4y+4] Substitute this expression for [x] into the second equation: [6(4y+4)-3y=-18] You now have one equation in one unknown. Solve for [y:] [24y+24-3y=-18] [21y=-42] [y=-2] Then [x=4y+4=4(-2)+4=-4] So the solution is x=-4,y=-2 Check by plugging back into both equations: -4-4(-2)=4 check! 6(-4)-3(-2)=-18 check!.

can u make more sentence?? I do not want to read. I need expain about these..... Solution Bed bugs, have resurged to quickly become a very important pest of the 21st century, as they invade numerous urban areas. Our society has had a 30+ year \"vacation\" from this pest, when bed bugs were almost completely removed from North America as a result of mass treatments with older types of insecticides (DDT, Chlordane, Lindane) Bed bugs are parasites that feed on the blood of people, using these blood meals to grow and reproduce. They do not distinguish between dirty or clean homes and all people are vulnerable to infestations in their homes. Bed bugs are also capable of feeding on animals, including dogs, cats, and other pets. Bed bugs typically cluster together in favorable harborage areas. However, some bed bugs will live by themselves, away from the rest of an infestation. The best way to determine if you have an infestation is to look for bed bugs where you sleep (or rest). In bedrooms, look particularly on and around boxsprings, mattresses, bed frames, tufts, folds, and buttons on mattresses, furniture, such as desks and chairs, behind wall paper, clocks and pictures, cracks in wood floors, and under the edge of carpet. If you travel also check your luggage, where you typically set it down when you enter your home and where you store it. While bed bugs are most commonly found in bedrooms, infestations can also occur in other rooms, including: bathrooms; living rooms; and laundry rooms. Dark blood spots on sheets and bedding may indicate bed bug feeding. Bed bugs will sometimes excrete while they are feeding. This results in darker (dark reddish or brownish) spots or smears found on bed sheets, pillowcases and mattresses, or in nearby areas. This material is composed mostly of digested blood and the stains are very characteristic. In severe infestations, bed bugs may be more noticeable. The accumulation of bugs, cast skins and fecal spots will be very apparent upon close inspection. Remember these insects are small and very flat, so they can move into very tight corners and cracks. In some infestations, they were found under picture frames, in between the glass and the frame and behind electrical outlet and other wall plates! Be prepared to do some close inspection and when in doubt, you should consider having the inspection done by a pest control service provider. You can use your washing machine and dryer to kill bed bugs that may be infesting clothes. Clothes laundered in hot water and/or dried in temperatures hotter than 122.

Can the Fed Prevent U.S. Recessions? Solution The Federal Reserve makes decisions based on great academic economists and veteran bank and corporate executives. Politics is minimal, at least compared to most other government decisions. Tremendous resources support the decisions, with great economists on staff, massive data banks and access to outside experts. You would think that the Fed can prevent recessions. You would be wrong. The Fed just released minutes from the policy meetings held in 2008, as they do regularly with a five-year time lag. The minutes depict a massive failure of the technocratic ideal of putting some smart people in the room and letting them run things. Chairman Ben Bernanke is quoted as saying that he is “confounded and muddled.” The Fed eased early in 2008 and patted themselves on their backs. In March, after the Bear Stearns rescue, Janet Yellen said that “the likelihood of a severe financial panic has diminished.” That could actually be accurate, if she meant that the likelihood was going from 99 percent to 98 percent. Tim Geithner, then president of the New York Fed, said in March 2008, “It is very hard to make the judgment now that the financial system as a whole or the banking system as a whole is undercapitalized. Some people are out there saying that . . . . Based on everything we know today, if you look at very pessimistic estimates of the scale of losses across the financial system, on average relative to capital, they do not justify that concern.” He further suggested that talk about the risks within the financial system was harmful, clearly favoring a “trust us” message to the public. This discussion happened well before Lehman declared bankruptcy and credit markets melted down. However, the people making decisions at the Fed (the Board of Governors plus the 12 regional bank presidents, four of whom vote at any one time) are neither stupid nor ignorant. They are all talented, and they know the issues. (On a personal note, my lasting memory of the Fed Board is that I was congratulating myself for having been invited to meet with them, and then Alan Greenspan asked the toughest question I had fielded since my doctoral dissertation. It was also the most critical question for the economy at the time. And I had to confess that I didn’t know the answer.).

Can someone show me how to prove this? I can easily use a DFA but i need it more general. Solution Buy the basic definition of regularity of a Language we mean that there is some mechanish buy which we can distinguish the member of a language from the non member in deterministic way. To handle a language containing infinite number of elements we use DFA\'s etc.. But if we know that the elements are finite we can easily check the membership of a language buy just checking will all the members of the language. In this way member ship is guarenteed to be find if the elements are finite. So if a language contains a finite amount of elements then it is Regular..

Can someone please help me with this question. Suppose that Xn, n = 1,2,3,... is a Bernoulli process with parameter p, i.e. P(Xn = 1) = p for all n. Suppose that Wn, n = 1,2,3,... is another Bernoulli process with parameter s. We assume that the two random processes are completely independent of each other (that is, any collection of samples of Xn is independent from any collection of Wn ). We form a new random process Yn, n = 1.2,3,... by defining Yn = Xn Wn, where the operation denotes mod 2 addition. This setup can be thought of as taking an input digital signal Xn and sending it across a binary channel to a receiver. The binary channel can cause an error between the input Xn and output Yn with probability s. Such a communication channel is called an additive noise channel because the output Is the input plus an independent noise process (where plus here means mod 2). We know that Yn is a Bernoulli process. Find its parameter, i.e. compute P(Yn = 1) If the signal 0 was sent, what is the probability that a 0 is received? a 1 is received? Find the conditional pmf Find an expression for the probability of error, i.e. P(Yn Xn). Solution (a)P(Y_n=1)= P(X_n=1,W_n=0)+P(X_n=0,W_n=1) = p(1-s)+s(1-p) = p+s-2ps (b)if signal 0 was sent,then the probability that 0 is received=p(X_n=0,W_n=0) = (1-p) (1-s) prob that a 1 is received=P(X_n=1,W_n=1) = ps (d)P(Y_n neq X_n) = P(X_n=1,W_n=1)+P(X_n=0,W_n=1) = ps+(1-p)s = s.

Solution Answer: Gauss gave the first clear exposition of complex numbers and of the investigation of functions of complex variables in the early 19th Century. Although imaginary numbers involving i(the imaginary unit, equal to the square root of -1) had been used since as early as the 16th Century to solve equations that could not be solved in any other way, and despite Euler.

Can someone please explain what a Poisson Process is and what it\'s used for? Solution The basic form of Poisson process, often referred to simply as \"the Poisson process\", is a continuous-time counting process {N(t), t = 0} that possesses the following properties: N(0) = 0 Independent increments (the numbers of occurrences counted in disjoint intervals are independent from each other) Stationary increments (the probability distribution of the number of occurrences counted in any time interval only depends on the length of the interval) No counted occurrences are simultaneous. Consequences of this definition include: The probability distribution of N(t) is a Poisson distribution. The probability distribution of the waiting time until the next occurrence is an exponential distribution. The occurrences are distributed uniformly on any interval of time. (Note that N(t), the total number of occurrences, has a Poisson distribution over (0, t], whereas the location of an individual occurrence on t ? (a, b] is uniform.) Other types of Poisson process are described below.

Can you solve these questions please with clear explanation Describe the main difference between Kaolinite and Montmorillonite clay minerals Differentiate between Sedimentary, Igneous and metamorphic Rocks. Identify the main Transportation agents for the following types of soil. Wind Sea (salt water) Lake (fresh water) River\" Ice Solution Minerals-Montmorillonite Minerals-Kaolinite The main difference between Igneous, Sedimentary and Metamorphic rocks, is the way that they are formed, and their various textures. Igneous Rocks Igneous rocks are formed when magma (or molten rocks) cool down, and become solid. High temperatures inside the crust of the Earth cause rocks to melt, and this substance is known as magma. Magma is the molten material that erupts during a volcano. This substance cools down slowly, and causes mineralization to take place. Gradually, the size of the minerals increase until they are large enough to be visible to the naked eye. Igneous rocks are mostly formed beneath the Earth’s surface. The texture of Igneous rocks can be referred to as Phaneritic, Aphaneritic, Glassy (or vitreous), Pyroclastic or Pegmatitic. Examples of Igneous Rocks include granite, basalt and diorite. Sedimentary Rocks Sedimentary rocks are usually formed by sedimentation of the Earth’s material, and this normally occurs inside water bodies. The Earth’s material is constantly exposed to erosion and weathering, and the resulting accumulated loose particles eventually settle, and form Sedimentary rocks. Therefore, one can say, that these types of rocks are formed slowly from the sediments, dust and dirt of other rocks. Erosion takes place due to wind and water. After thousands of years, the eroded pieces of sand and rock settle, and become compacted to form a rock of their own. Sedimentary rocks range from small clay-size rocks to huge boulder-size rocks. The textures of Sedimentary rocks are mainly dependent on the parameters of the clast, or the fragments of the original rock. These parameters can be of various types, such as surface texture, round, spherical or in the form of grain. The most common type of Sedimentary rock is the Conglomerate, which is caused by the accumulation of small pebbles and cobbles. Other types include shale, sandstone and limestone, which is formed from clastic rocks and the deposition of fossils and minerals. Metamorphic Rocks Metamorphic rocks are the result of the transformation of other rocks. Rocks that are subjected to intense heat and pressure change their original shape and form, and become Metamorphic rocks. This change in shape is referred to as metamorphism. These rocks are commonly formed by the partial melting of minerals, and re-crystallization. Gneiss is a commonly found Metamorphic rock, and it is formed by high pressure, and the partial melting of the minerals contained in the original rock. Metamorphic rocks have textures like slaty, schistose, gneissose, granoblastic or hornfelsic. Examples of these types .

Can you write an essay of 350 words about the history of bitumen. Solution HISTORY OF BITUMEN Bitumen has been used for centuries in variety of ways that include the preservation of mummies by the Egyptians and the waterproofing of baths by Babylonians. Bitumen was used in its natural state until the early 1900s when the distillation of crude oil began. The use of asphalt in built up roofing was normally restricted to use on steep slope roofs (1 inch to 3 inches per foot) prior to the late 1940s and early 1950s when, by modification during the manufacturing process, a product was developed that was suitable for use of low slope roofs (1/4 inch per foot or greater) HISTORY OF THE DEVELOPMENT OF MODIFIED BITUMEN ROOFING DEFINITION: Perhaps it is appropriate to define MB roofing as used for this paper. A modified Bitumen roofing membrane is not usually a true single ply roofing membrane, but is usually used in conjunction with a base ply of similar or different roofing material. Under strictly controlled circumstances, it may be used as a pure single ply roofing membrane. DEVELOPMENT DATES Other important dates for European bitumen development include: Bitumen is still the preferred geological term for naturally occurring deposits of the solid or semi-solid form of petroleum. Bituminous rock is a form of sandstone impregnated with bitumen. The oil sands of Alberta, Canada are a similar material. Bitumen is sometimes incorrectly called \"tar\" (tar is a black viscous material obtained from the destructive distillation of coal and is chemically distinct from bitumen). In Australian English, bitumen is sometimes used as the generic term for road surfaces. In Canadian English, the word bitumen is used to refer to the vast Canadian deposits of extremely heavy crude oil, while asphalt is used for the oil refinery product used to pave roads and manufacture roof shingles and various waterproofing products. Diluted bitumen (diluted with naphtha to make it flow in pipelines) is known as Dilbert in the Canadian petroleum industry, while bitumen \"upgraded\" to synthetic crude oil is known as sync rude and sync rude blended with bitumen as \"synbit\". Bitumen (or asphalt) is primarily used, when mixed with mineral aggregates, to produce paving materials. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs. Most natural bitumen contain sulfur and several heavy metals such as nickel, vanadium, lead, chromium, mercury and also arsenic, selenium, and other toxic elements. Bitumen can provide good preservation of plants and animal fossils. Naturally occurring crude bitumen impregnated in sedimentary rock is the prime feed stock for petroleum production from \"oil sands\", currently under development in Alberta, Canada. Canada has most of the world´s supply of natural bitumen, covering 140,000 square kilometers (an area larger than England), giving it the second largest proven oil reserves.

Can you write a report about steel.In your report you need to include the types of steel,the manufacturing process of steel,the application of steel in construction and also the advantages and disadvantages of steel.You need to write your answer neatly so that I can see and understand it easily. Solution INTRODUCTION Steel is an alloy of iron and other elements, primarily carbon, that is widely used in construction and other applications because of its high tensile strength and low cost. Steel\'s base metal is iron, which is able to take on two crystalline forms (allotropic forms), body centered cubic (BCC) and face centered cubic (FCC), depending on its temperature. , it’s one of the most popular metals in fabrication shops. TYPES OF STEEL 1) Carbon Steels: Carbon steels contain trace amounts of alloying elements and account for 90% of total steel production. Carbon steels can be further categorized into three groups depending on their carbon content: 2) Alloy Steels: Alloy steels contain alloying elements (e.g. manganese, silicon, nickel, titanium, copper, chromium and aluminum) in varying proportions in order to manipulate the steel\'s properties, such as its hardenability, corrosion resistance, strength, formability, weldability or ductility. Applications for alloys steel include pipelines, auto parts, transformers, power generators and electric motors. 3) Stainless Steels: Stainless steels generally contain between 10-20% chromium as the main alloying element and are valued for high corrosion resistance. With over 11% chromium, steel is about 200 times more resistant to corrosion than mild steel. These steels can be divided into three groups based on their crystalline structure: 4) Tool Steels: Tool steels contain tungsten, molybdenum, cobalt and vanadium in varying quantities to increase heat resistance and durability, making them ideal for cutting and drilling equipment. 2) Deformed steel bars Mild steel bars are used for tensile stress of RCC (Reinforced cement concrete) slab beams etc. in reinforced cement concrete work. These steel bars are plain in surface and are round sections of diameter from 6 to 50 mm. These rods are manufactured in long lengths and can be cut quickly and be bent easily without damage. As deformed bars are rods of steels provided with lugs, ribs or deformation on the surface of bar, these bars minimize slippage in concrete and increases the bond between the two materials. Deformed bars have more tensile stresses than that of mild steel plain bars. These bars can be used without end hooks. The deformation should be spaced along the bar at substantially uniform distances. To limit cracks that may develop in reinforced concrete around mild steel bars due to stretching of bars and some lose of bond under load it is common to use deformed bars that have projecting ribs or are twisted to improve the bond with concrete. These bars are produced in sections from 6 mm to 50 mm dia. In addition the strength of bonds of d.

Can you help with the answers for Twin falls community hospital questions? / 4 1 Copyright 2013 6/15/12 Case 5 Twin Falls Community Hospital (Capital Investment Analysis) Twin Falls Community Hospital is a 250-bed, not-for-profit hospital located in the city of Twin Falls, the largest city in Idaho’s Magic Valley region and the seventh largest in the state. The hospital was founded in 1972 and today is acknowledged to be one of the leading healthcare providers in the area. Twin Falls’ management is currently evaluating a proposed ambulatory (outpatient) surgery center. Over 80 percent of all outpatient surgery is performed by specialists in gastroenterology, gynecology, ophthalmology, otolaryngology, orthopedics, plastic surgery, and urology. Ambulatory surgery requires an average of about one and one-half hours; minor procedures take about one hour or less, and major procedures take about two or more hours. About 60 percent of the procedures are performed under general anesthesia, 30 percent under local anesthesia, and 10 percent under regional or spinal anesthesia. In general, operating rooms are built in pairs so that a patient can be prepped in one room while the surgeon is completing a procedure in the other room. The outpatient surgery market has experienced significant growth since the first ambulatory surgery center opened in 1970. This growth has been fueled by three factors. First, rapid advancements in technology have enabled many procedures that were historically performed in inpatient surgical suites to be switched to outpatient settings. This shift was caused mainly by advances in laser, laparoscopic, endoscopic, and arthroscopic technologies. Second, Medicare has been aggressive in approving new minimally invasive surgery techniques, so the number of Medicare patients utilizing outpatient surgery services has grown substantially. Finally, patients prefer outpatient surgeries because they are more convenient, and third-party payers prefer them because they are less costly. These factors have led to a situation in which the number of inpatient surgeries has grown little (if at all) in recent years while the number of outpatient procedures has been growing at over 10 percent annually and now totals about 22 million a year. Rapid growth in the number of outpatient surgeries has been accompanied by a corresponding growth in the number of outpatient surgical facilities. The number currently stands at about 5,000 nationwide, so competition in many areas has become intense. Somewhat surprisingly, there is no outpatient surgery center in the Twin Falls area, although there have been rumors that local physicians are exploring the feasibility of a physician-owned facility. 2 The hospital currently owns a parcel of land that is a perfect location for the surgery center. The land was purchased five years ago for $350,000, and last year the hospital spent (and expensed for tax purposes) $25,000 to clear the land and put in sewer and utility .

Can you pleae provide site documentation, thank you Week 7 Discussion \"Contingencies\" Please respond to the following: From the e-Activity, briefly discuss the type of contingencies that Coca Cola is involved in and the accounting treatment of such contingencies. Give your opinion on whether the notes to the financial statements disclose the necessary information on the contingencies for interested parties to make an investing decision. Based on the information disclosed, decide whether you would you invest in Coca Cola. Justify your rationale. Suppose management is involved in a situation where the outcome of the situation is contingent upon certain events to occur; however, management is unsure of the generally accepted accounting principles for reporting contingencies. You are the senior accountant, and management has tasked you with preparing a report on contingencies. Distinguish between a gain contingency and a loss contingency, and highlight the accounting treatment for each type of contingency. Also, recommend two (2) improvements to the reporting requirements on loss contingencies to FASB. Solution A gain contingency is an uncertain situation that will be resolved in the future, possibly resulting in a gain. The accounting standards do not allow the recognition of a gain contingency prior to settlement of the underlying event. Doing so might result in the excessively early recognition of revenue (which violates the conservatism principle). Instead, one must wait for the underlying uncertainty to be settled before a gain can be recognized. If a contingency may result in a gain, it is allowable to disclose the nature of the contingency in the notes accompanying the financial statements. However, the disclosure should not make any potentially misleading statements about the likelihood of realization of the contingent gain. Doing so might lead a reader of the financial statements to conclude that a gain would be realized in the near future. A loss contingency is a charge to expense for what is considered to be a probable future event, such as an adverse outcome of a lawsuit. A loss contingency gives the readers of an organization\'s financial statements early warning of an impending payment related to a likely obligation. If the amount of such a loss cannot be reliably estimated and is not considered probable, an entity may still choose to discuss the item in the footnotes that accompany its financial statements. There are three scenarios for loss contingent liabilities, all involving different accounting treatments. They are:.
