Given X=[b, a,4,a],Y=[c, d,a, b], and Z=[a, c,16,b], what is Y if X-2Y=Z

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)

Determine the solution for mc001-1.jpeg

The discrete random variables x and y take integer values with joint probability distribution given by f (x, y) = a(y−x+1) 0 ≤ x ≤ y ≤ 2 or =0 otherwise, where a is a constant. 1 tabulate the distribution and show that a = 0.1.2 find the marginal distributions of x and y. 3 calculate cov(x, y).4 state, giving a reason, whether x and y are independent. 5 calculate e(y|x = 1).
