(b)
Answer to Problem 13E
The graph is shown in Figure 4 and it shows that after 0.02 hours 1.2 min the customers are served.
Explanation of Solution
Given:
The average calls are 34 calls per hour.
Calculation:
The average call is 34 then the model is,
By the use graphing utility press Y= and enter the model in the calculator as shown in Figure 1
