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) = 5 E(Y) = 7 Var (X) = 9 Var (Y) 34 Var (z) = 29 E(Z) = 0 Compute the values of the expressions below. E (5 + x) - I -4Z + 4Y Var (-Sx) + 1 ] (22") - O
