During an eight-hour shift, the proportion of timey that a sheet-metal stamping machine is down for maintenance or repairs has a beta distribution with α = 1 and β = 2. that is
2(1−y) , 0 ≤ y ≤ 1,
f(y)
0, elsewhere.
the cost (in hundreds of dollars) of this downtime, due to lost production and cost of maintenance and repair, is given by c = 10 + 20y + 4y^2. find the mean and variance of c.
