Suppose that X, Y, and Z are jointly distributed random variables, that is, they are defined on the same sample spac Suppose that we also have the following. E(Y)=9 Var(X) = 24 Var(Y) = 19 Var(Z) = 45 E(X) =-8 E (Z) = 2 Compute the values of the expressions below. 믐 E(-5Y-2) = | 5Y-3X ? E()= 0 2 -2+Var(-4Y) = 0 E(-4x²) = 0
