Customers arrive at a checkout counter in a department store according to a Poisson distribution at an average of eight per hour. If it takes approximately ten minutes to serve each customer, find the mean and variance of the total service time in minutes for customers arriving during a 1-hour period. (Assume that a sufficient number of servers are available so that no customer must wait for service.)

3, nah jk it's 2

step-by-step explanation:

it is 3 cause i'm sanic

p(x)= 8 x³ - 36 x² + 54 x - 27

q(x) = 2 x -3

you can check your mistake and then you can choose the correct option.

dividend =   8 x³ - 36 x² + 54 x - 27

divisor = 2 x -3

if you want to find quotient, proceed as follows

q(x)= 0

2 x - 3=0

x =

now , i have used division method , to find quotient and remainder

it would be 198 people.

hope it

3x-x+2=4 i think that's is the answer, and i hope it you
