Extracted text: (4) For each of the following cases identify those f(x, y) which can be made into bivariate densities by chossing an appropriate value of C. Provide the value of C . n f (x, y) = c, on [0, 5] × [1,7], Giin f (x, y) (ixo f (x, y) = ce-2x–3y y. on (0, 1) × (0, 1), ху , for X, у > 0, Here are some proposed answers. (`Yes" means the function is a density for the stated constant C) No Yes, c = 30 Yes, c = Yes, c = 35 Yes, c = N/A (i- Select One) No Yes, c = 1 Yes, c = 2 Yes, c = = Yes, c = +∞ N/A (iii- Select One) No Yes, c = 1 Yes, c = Yes, c = Yes, c = 6 N/A (ix- Select One) 1/2
