The coff-e-cup beverage company has opened two franchises in town. they put one location in the center of town and one at the west end of town. let x be the number of customers that enter the center of town location in an hour, and y be the number of customers that enter the location at the west end of town in an hour. assuming that μx = 65 with σx = 4.3 and μy = 45 with σy = 3.2 , what is the mean of z, the total number of customers that enter these locations in an hour?

The mean of Z, the total number of customers that enter these locations in an hour is 110.

Step-by-step explanation:

Consider the provided information.  

Let X be the number of customers that enter the center of town location in an hour,

Let Y be the number of customers that enter the location at the west end of town in an hour.

Assuming that

X and Y are independent random variables.

The expected value of the sum of random variables is equal to the sum of their individual expected values.

Hence, the mean of Z, the total number of customers that enter these locations in an hour is 110.
