Hello can you help me? How can I solve this question? x By .(x, y) = (0,0) f (x, y) = xraya (x,y) = (0,0) no+? for this function at (0,0) point, is this faction continuous or Show it properly
3. Let the joint probability density function of W, X, Y, and Z be for,x, y, z) = elsewhere (a) Find the marginal joint probability density function fw.x(w, z). (b) Use part (a) to compute P(O< W<X<1). 3. Let the joint probability density function of W, X, Y, and Z be for,x, y, z) = elsewhere (a) Find the marginal joint probability density function fw.x(w, z). (b) Use part (a) to compute P(O
The joint probability density function of random variables X and Y is given by f(x,y) ={10xy^2 0≤x≤y≤1,0 otherwise. (a) Compute the conditional probability fX|Y(x|y). (b) Compute E(Y) and P(Y >1/2). (c) Let W=X/Y. Compute the density function of W. (d) Are X and Y independent? Justify briefly.
2. (10 pts The random variables X and Y have joint density function f(x, y) == 22 + y2 <1. Compute the joint density function of R= x2 + y2 and = tan-1(Y/X).
Please help me solve this question, thank you! If the function z -f(x,y) has continuous second order partial derivatives f(x, y), fry (x,y)- fyr(r, ), fw(x, y), and if co 0, y sin 0, show that ух んyy
