The manager of an industrial plant is planning to buy a new machine. For each day’s operation, the number of repairs X, that the
machine needs is a Poisson random variable with mean 0.96 repairs per day. The daily cost of operating the machine is C = 160 + 40X2 . Find the expected value of the daily cost of operating the machine.
What you must do for this case is to rewrite the first expression to find its value. We have then: 153 = 2 (z + z) n Rewriting: 153 = 2n2z Then, 2n (2z) -193 Substituting 153-193 = -40 Answer: the value of 2n (2z) -193 is -40
