a) average number in the system divided by the arrival rate
b) average number in the system divided by the service rate
c) average service time divided by the arrival rate
d) average arrival rate divided by the service rate

Answer 1

The average time a customer is in the system for infinite source models can be found by dividing the average number in the system by the arrival rate.

Step-by-step explanation:

The average time a customer is in the system for infinite source models can be found by dividing the average number in the system by the arrival rate. So the correct option is a) average number in the system divided by the arrival rate. This is because the arrival rate represents the rate at which customers enter the system, and dividing the number in the system by the arrival rate gives us the average time a customer spends in the system.
