14-12 From historical data, Harry?s Car Wash estimates that dirty cars arrive at the rate of 10 per hour all day Saturday. With a crew working the wash line, Harry figures that cars can be cleaned at the rate of one every 5 minutes. One car at a time is cleaned in this example of a single- channel waiting line. Assuming Poisson arrivals and exponential ser-vice times, find the;(a) average number of cars in line.;(b) average time a car waits before it is washed.;(c) average time a car spends in the service system.;(d) utilization rate of the car wash.;(e) probability that no cars are in the system.
