Step-by-step explanation:
During an eight-hour shift, the proportion of time y that a sheetmetal stamping machine is down for maintenance or repairs has a
beta distribution with α = 1 and β = 2. that is f(y) = 2(1 − y), 0 ≤ y ≤ 1, 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.

Step-by-step explanation:
Given: The manager of a department store uses the given function to model the monthly opening inventory of down comforters at the store, in dollars, where x represents the number of months from September.
To rewrite this hat reveals the store's opening inventory of down comforters in the month of September, multiply -750 on the bracket, we get
Under the given transformation, the Jacobian and its determinant are
so that
where is the region
transformed into the
-
plane. The remaining integral is the twice the area of
.
Now, the integral over is
but through the given transformation, the boundary of is the set of equations,
We require that , and the last equation tells us that we would also need
. This means
and
, so that the integral over
is
