At the superspeedy drive-through the time between consecutive customer arrivals has a mean of 50 seconds and a standard deviation of 30 seconds. there are two servers whose service time averages 80 seconds with a standard deviation of 20 seconds. assume that no customers leave the drive-through after entry. a. what is the utilization of the employees?

utilization of employee is 80%

Step-by-step explanation:

Given data:

mean = 50 sec

standard deviation is 30 sec

Average number of arrivals/ sec is

service rate id 80 sec

The utilzation of employee is calculated as

i.e 80%

utilization of employee is 80%

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =    

hope this you and

step-by-step explanation:

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
