Kidney transplant in 2012 have interarrival times that are independent with a common distribution that is exponential with mean 3 per month. Calculate the probability that at least three kidney transplant claims will arrive between January 1, 2012 and March 1, 2012 Solution So nos. of transplants will follow Poisson distribution =rate*time=3*2=6 P(x=k)= e-k/k! P(X>=3) = 1-P(X<3) = 1-P(x=0)-P(x=1)-P(x=2)= 1- e-6- 6*e-6-18*e-6= 0.938.

Law that is dubbed higher than human law is called? Solution Higher law as normative for the Constitution is, therefore,twofold. The founders adhered to two conceptions of higher law inestablishing the Constitution: one empirical and the othernonempirical. The empirical conception of higher law signifies that, likephysical nature, human nature and society in history displayregularities of connections between facts that can be fruitfullygeneralized into maxims or scientific laws..

Lastly, discuss the financial statements that must be presented by a government university that engages in only business-type activities? Is there a GASB or FASB requirement that mandates this type of implementation? Solution Most businesses have a goal of earning profit for stockholders. Thus, the financial statements of most businesses are designed to allow stockholders and others concerned with profitability a means to monitor the performance of the business in question. Universities, colleges and other non-profit organizations ostensibly have an entirely different purpose. Universities and colleges, in particular, are institutions of higher learning established primarily to create and disseminate knowledge. Universities and colleges receive a significant portion of their funding from donors and governmental entities. These funds are often given with certain restrictions and conditions. Consequently universities use a system of fund accounting. The primary purpose of fund accounting is to provide trustees, who are legally responsible for running universities, the information to monitor the funds that come into the institution and make sure that they are expended for their intended purpose. The Governmental Account Standards Board (GASB) governs the reporting of financial data for public universities and colleges. In 2002, public universities and colleges changed their financial statements so that they more closely resemble those in for profit businesses (GASB 34). The Financial Accounting Standards Board (FASB) governs private universities and colleges financial statements. FASB changed the way that private universities and colleges report financial data before 2002. The effect of the changes of GASB and FASB on the way universities and colleges report their financial data was to put it in a format that much more closely aligned with for profit businesses. To get a true picture of a university’s finances, one must look at the actual financial statements, which represent the actual revenues and expenses of a university. Non-profit organizations, such as universities and colleges, take in revenue in the form of tuition dollars, donations and governmental support. In the process of carrying out the mission of their institution, universities incur expenses. The difference between the revenues that come into a university or college and its expenses is known as a change in net assets. If a university takes in more revenue then it expends, there is a positive increase in net assets (i.e. net income). Conversely, if the expenses exceed the revenues there is a decrease in net assets (i.e., a net loss). Increases or decreases in net assets are one of the prime indicators of how a university or college is performing financially. Financial data is reported either as a stock or flow. A stock means measurement takes place in dollars without respect to time. For example, the amount of money in your savings account is a stock. Flows are measurements that .

Lake Aberdeen has a mean phosphorus conc. of 14.6 mg/L and standard deviation of 5.8 mg/L. Random day selected. Q: What is the probability that the total phosphorus differs from the mean by more than 5mg/L? Can you explain how to do this problem? Thank-you Solution Normal Distribution Mean ( u ) =14.6 Standard Devaition ( sd )=5.8 Normal Distribution = Z= X- u / sd ~ N(0,1) P(X > 19.6) = x-U/5.8 = 5/5.8 = 0.8621 = P ( Z >0.8621) From Standard Normal Table = 0.19432.

Kirkpatrick and Locke (1991) in an earlier reading provided us with insight into the role of personal traits and their contribution to the emergence of a leader. Discuss how people possessing the “right stuff” tend to surface as leaders. In similar fashion, what clues to the emergence of leaders are provided by the writings of Murphy (1941) and Smircich and Morgan (1982)? Solution The \"right stuff\" is the ability to convince others. Charisma, personality - call it what you will. Approaching leadership as a relationship between leaders and followers or as a set of behaviors and competencies that anyone can develop provides a much more optimistic, democratic, and inclusive picture of leadership. These latter approaches emphasize that given the right experiences, circumstances, and training, each of us has both the capacity and the ability to enact effective leadership, regardless of the specific traits and personality characteristics with which we were born..

Kim went to Ling\'s market to pick up few items for dinner. It was a stormy day, and the wind had blown water through the market\'s door each time it opened. As Kim entered through the door, she slipped and fell in the rainwater that had accumulated on the floor. The manager knew of the weather conditions but had not posted any sign to warn customers of the water hazard. Kim injured her back as a result of the fall and sued Ling\'s for damages. Can Ling\'s be held liable for negligence? Solution You have a store owner, who is considered to open his premises to the general public (who are considered invitees) and to, therefore, owe a duty to that public to make his premises safe for them to be inside. A reasonable store owner would know that he needs to fix any dangerous situation, such as water puddles that can make the entrance slippery. Here Ling failed to do that. That means that he breached his duty. That breach caused injury to Kim and her injury was both foreseeable and the direct result of Ling\'s negligence.

Kim Falgout\'\'s daughter, Madeline, has a piggy bank with 54 coins. some are uarters, and the rest are half dollars. If the total value of the coins is $17.00, how many of each denomination dooes she have? Solution assume x coins are quarter so 54-x will be halfs. total amount will be= (x/4)+((54-x)/2)=17 so (x/4)+27-(x/2)=17 or (x/4)= 10 or x= 40. so quartes coins are 40 and halfs coins are 54-40= 14. proof : 40 coins quarter, so amount= 40(1/4)=10 14 are halfs so amount = 14(1/2)= 7 total = 10 + 7 =17. hence prooved..

Kiddo Company manufactures and ships children’s stuffed animals across the nation. The following are profit statements for the company’s two lines of business: Costs that are easily associated with each line of business are included in the direct costs. Allocated costs include costs that are not directly traced to the business units. These costs include employee benefits, rent, telecommunications costs, and general and administrative costs, such as the salary of the CEO of Kiddo. At the start of 2014, allocated costs were estimated as follows: In the past, allocations have been based on headcount (the number of employees in each business unit). There were 210 employees in Stock and 70 employees in Custom. The new controller of Kiddo believes that the key driver of employee benefits and telecommunications costs is headcount. However, rent is driven by space occupied, and general and administrative costs are driven by relative sales. Kiddo rents 42,000 square feet; approximately 21,000 is occupied by Stock employees and 21,000 by Custom personnel. Prepare profit reports for Stock and Custom, assuming the company allocates costs using headcount, space occupied, and sales as allocation bases. (Enter loss using either a negative sign preceding the number e.g. -45 or parentheses e.g. (45).)

Wizards are very useful for creating a good user experience. In all businesses, interactive sessions are most beneficial. To improve the user experience, wizards in Odoo provide an interactive session. For creating wizards, we can use transient models or abstract models. This gives features of a model class except the data storing. Transient and abstract models have permanent database persistence. For them, database tables are made, and the records in such tables are kept until they are specifically erased.
