please help with these questions 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.
The following system of three nonlinear algebraic equations is to be solved forx, y, z as functions of the variables u, v,w:u = x + y + zv = x2 + y2 + z2w = x3 + y3 + z3a. Prove or find a counter example: for each (u,v,w) near (0,2,0), there is a uniquesolution (x,y,z) near (-1,0, 1).b. Is the Implicit Function Theorem applicable for (u,v,w) near (2, 4, 8) and(x,y, z) near (0, 0, 2)?
For U = {q, r, s, t, u, v, w, x, y, z}A = {q, s, u, w, y}B = {q, s, y, z}C = {v, w, x, y, z}identify the following.5) CA) {v, w, x, y, z}B) {q, r, s, t, u}C) { }D) {v, z}
Define an equivalence relation on R by (x,y,z) ∼ (u,v,w) whenever x +y +z = u +v +w . Describe the equivalence classes.
solved item S, T, U, V, W, X, Y, Z The demand for subassembly S is 100 units in week 7. Each unit of S requires 2 units of T and 1 unit of U. Each unit of T requires 1 unit of V, 2 units of W, and 1 unit of X. Finally, each unit of U requires 1 unit of Y and 2 units of Z. One firm manufactures all items. It takes 2 weeks to make S,...
