Suppose that X, Y, and Z are jointly distributed random variables, that is, they are defined on the same sample space. Suppose that we also have the following. E(X) = 1 E(Y) =0 E(Z) = 4 Var (X) = 23 Var (Y) = 46 Var (z) = 30 Compute the values of the expressions below. E (5 + 5x) 3X + 5Z Var(sY) - I 4- z (37') - 0 E3Y
