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.
Answers: 3
![E[c]=160+40E[x^2]\\\\E[c]=160+40(Var[x]+(E[x])^2)\\\\E[c]=160+40(0.96+0.96^2)\\\\E[c]=235.264](/tpl/images/0424/6729/8dbd2.png)
