7. Find fryzx, for f(x, y, z) = 3 + 2?x – xyz + x+y 8. Use the chain rule to calculate that t = 0, if z = sin(xy), x = 1+1, y = 12 + 2t. 9. Use the chain rule to find us at (u, v) = (1,0), when z = xy, x = u +v?, y = x + v.
1. Suppose that E(X) E(Y) E(Z) 2 Y and Z are independent, Cov(X, Y) V(X) V(Z) 4, V(Y) = 3 Let U X 3Y +Z and W = 2X + Y + Z 1, and Cov(X, Z) = -1 Compute E(U) and V (U) b. Compute Cov(U, W). а.
let u= ln(x) and v=ln(y) w=ln(z) where x,y,z>0 .Write thr following wxpressiins in terms of u,v, and w. a) ln( squareroot x^5)/ y^3z^2) B) ln (squareroot x^3 4squaroot y)
