In a single-channel, single-phase queuing (waiting line) system, it is reasonable to assume Poisson arrivals with average arrival rate of 2 customers per hour. It is also reasonable to assume Negative Exponential service time with average service rate of 4 customers per hour. Based on these information, the average time (in hours) a customer spends waiting in the queue is

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
