I think u forgot to put the whole question
The number of large boxes is 4 and the number of small boxes is 14.
<u><em>Explanation</em></u>
Suppose, the number of large boxes is 
and the number of small boxes is 
As, the total number of boxes is 18, so the first equation is....
The large boxes hold 35 books, and the small ones hold 20 books and the total number of books is 420. So the second equation will be .....
Now solving equation (1) for itself , we will get....
We will plug this into equation (2). So.....
Now plugging this 
into the equation .......
Thus, the number of large boxes is 4 and the number of small boxes is 14.
Answer:
2.719 minutes
Step-by-step explanation:
Step 1 :
We have to consider using the M/G/I /GD /∞/∞ Queuing system with the rate of arrival λ and the rate of service μ.
Since average of 40 cars arrive every hour at the painting facility, it follows that:
Arrival rate λ = 40cars /hour
= 40/60 cars/hour
=2/3 cars/hour
More, we were told that 95% of the cars require 1 minute to paint, 5% must be painted twice and require 2.5 minutes to paint, therefore, the average time to paint a car is given by
95/100x1 + 5/100 x 2.5 = 19/20 + 1/8 = 43/40min
It follows that:
Service rates μ = 40/43cars/min
