Answer:Answer:

The % of time the machine is used​ is 69.44%

Step-by-step explanation:

According to the given data we have the following:

Arrival rate = λ=50 per hour

Service rate = μ=72 per hour​

a) Therefore, in order to calculate The percentage of time the machine is used we would have to make the following calculation:

The percentage of time the machine is used​= λ/ μ

The percentage of time the machine is used​=50/72

The percentage of time the machine is used​= 0.6944 = 69.44%

The percentage of time the machine is used​ is 69.44%
