The document discusses complaints received by an internet brokerage firm. The firm receives complaints at a rate of 4 per day, which follow a Poisson distribution. It asks for the probability of receiving 3 or more complaints in a day and 11 or more complaints over a 3-day period.

Formation

Complaints about an intemet brokerage firm occur at a rate of 4 per day. The number of
complaints appears to be Poisson distributed. A. Find the probobility that the firm receives 3 or
more complaints in a day. Probability 8. Find the probability that the firm receives 11 or more
complaints in a 3-doy period. Probability = input ansivers to four decimals.

Conjugation, transduction, and transformation are important mechanisms in bacteria to promote exchange of genetic material. The figure below shows the age of horizontally acquired genes in a strain of E. coli where at least 755 genes [more than one-sixth of this strain's genomel have been acquired by horizontal transfer and the majority of those genes have been transferred quite recently. If bacteria still often engage in horizontal gene transfer events why haven't bacteria increased in complexity?.

Concert marketing: GSU's Rialto Center for the Performing Arts wanted to investigate why ticket sales for the upcoming season significantly decreased from last year's sales. The marketing staff collected data from a survey of community residents. Out of the so people surveyed, only 7 received the concert brochure in the mail. Which of the following is a reason that the marketing staff should not calculate a confidence interval for the proportion of all community residents who received the concert brochure by mail? Check all that apply. A. The sample needs to be random, but we don't know if it is. B. The actual count of community residents who received the concert brochure by mail is too small. C. OThe actual count of community residents who didn't receive the concert brochure by mail is too small. D. np is notgreater than 10 E. n(1p^) is not greater than 10 ..

Conclusin para espectrofotmetro (Necesito una conclusin para el espectrofotmetro) INTRODUCCIN El espectrofotmetro es un instrumento utilizado para medir los espectros de muestras y reas microscpicas. Se utiliza para medir espectros NIR UV visibles de muestras microscpicas. Mide la transmisin, la absorcin, la reflectancia, la polarizacin y la fluorescencia de una muestra determinada. Est diseado como un microscopio ptico combinado con un espectrofotmetro NIR UV visible. Mide un rango de muestras de hasta 1 x 1 micrmetro. Con la ayuda del software, se pueden realizar medidas de mapeo 3D y calorimetra. Con esto es posible la medicin del espesor de pelcula delgada de micropuntos sin contacto. Tiene una gran influencia en el campo de la investigacin y la industria. Dado que tiene un gran rango espectral, los cientficos e ingenieros lo utilizan para obtener espectros de reas de muestra extremadamente pequeas. Incluso funciona en el campo donde la luz visible y el infrarrojo no funcionan. Por ejemplo, un cientfico forense o un qumico lo usa para combinar fibras o pinturas de muestras microscpicas. Un gelogo puede usarlo para la calificacin de gemas. RESULTADO DE APRENDIZAJE 1. El funcionamiento mecnico bsico del espectrofotmetro secomam PRIM. 2. Los principios bsicos de la espectrofotometra, incluida la relacin/clculo del valor de transmitancia (T) y absorbancia (A). 3. Identificar la absorbancia mxima (A max) de un compuesto y cmo se determina. 4.Comprender el uso del estndar de protenas. METODOLOGIA A.Determinar el espectro de absorbancia y la longitud de onda de mxima absorbancia El instrumento que se utilizara en esta prctica es el Secomam PRIM. 1. El espectrofotmetro est encendido. calent el mquina durante 15 minutos. 2. Se presion el botn Val para activarlo. 3. El botn de transmitancia ha sido seleccionado por el utilizado del botn A 4. La longitud de onda se ha fijado en 375nm. 5. La cubeta se limpi y sec. 6. Se coloc la solucin en blanco y la cubeta en el portamuestras del espectrmetro. 7. Se presion el botn cero. 8. Se ha retirado la cubeta con la solucin en blanco. 9. Se limpi y sec otra cubeta. 10. La solucin estndar A se verti en la cubeta y la cubeta se coloc en el portamuestras del espectrmetro. 11. La transmitancia se registra en el papel de resultados. 12. Se retir la cubeta con la solucin estndar A. 13. La longitud de onda se cambia a 425 nm 14. La cubeta con la solucin en blanco se coloc en el portamuestras del espectrofotmetro. 15. Se presion el botn cero. 16. Se retir la cubeta con la solucin en blanco. 17. La cubeta con la solucin estndar A se coloc en portamuestras del espectrmetro. 18. La transmitancia se registra en el papel de resultados. 19. Se retir la cubeta con la solucin estndar A. 20. Paso 13 a paso 19 para diferentes longitudes de onda: 490, 530, 540, 550, 580, 625 y 700nm. 21. La absorbancia se calcul en papel de resultados. 22.
