Solve the equation (3x?y - 1)dx + (y - 4x?y-2)dy = 0 is an arbitrary constant, and V by multiplying by the integrating factor. An implicit solution in the form F(x,y) = C is = C, where (Type an expression using x and y as the variables.)
13. (8 pts.) Two random variables have the following pdf fxx (x, y) = {4x(1–» (4x(1 - y),0 < x <1,0 < y < 1 0, otherwise Find P[X<Y] 14. We are interested in the average escape time for firemen participating in a drill that involves escaping a dangerous situation. A random sample of 26 escape times is taken and gives a mean of 24.36 with a variance of 370.69. We wish to find a 95% confidence interval for the...
