Support requests arrive at a software company at the rate of 1 every 10 minutes. assume that the requests arrive as events in a poisson process. a. what is the expected number of requests in an hour? give an exact answer. 6 correct: your answer is correct. b. what is the probability that the number of requests in an hour is between 8 and 10 inclusive? give your answer to four decimal places. c. what is the expected number of requests in a 10 hour work day? give an exact answer. d. what is the probability that the number of requests in a 10 hour work day is between 64 and 68 inclusive? give your answer to four decimal places. e. what is the standard deviation of the number of requests in a 10 hour work day? give your answer to four decimal places.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
