An internal study by the technology services department at lahey electronics revealed company employees receive an average of "2.7" non-work-related e-mails per hour. assume the arrival of these e-mails is approximated by the poisson distribution. a. what is the probability linda lahey, company president, received exactly 3 non-work-related e-mails between 4 p. m. and 5 p. m. yesterday

0.2205

Step-by-step explanation:

Given : Technology Services department at Lahey Electronics revealed company employees receive an average of "2.7" non-work-related e-mails per hour.

i.e.

If the arrival of these e-mails is approximated by the Poisson distribution.

Then , the required probability is given by :-

Hence, the probability Linda Lahey, company president, received exactly 3 non-work-related e-mails between 4 P.M. and 5 P.M. yesterday =0.2205

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
