.129 During an eight-hour shift, the proportion of time Y that a sheet-metal stamping machine is down for maintenance or repairs has a beta distribution with a = 1 and ß = 2. That is, [2(1-y), 0≤ y ≤ 1, elsewhere. f(y) = 0, The cost (in hundreds of dollars) of this downtime, due to lost production and cost of mainte- nance and repair, is given by C = 10 + 20Y +4Y². Find the mean and variance of C.
