Answer:
Step-by-step explanation:
Given that the bivariate distribution of X and Y is described below:
x 1 2
y
1 0.21 0.14 0.35
0 0.47 0.18 0.65
Pdf of Y is
Y 1 0
p 0.68 0.32
C) Pdf of X is
x 1 2
p 0.35 0.65
Mean of X = 
Var(x) = E(x^2)-Mean ^2 = 
C) Mean of Y = 1(0.68)+0 = 0.68
Var(y) = 1(0.68)-0.68^2
= 0.2176

Answer:
85
Step-by-step explanation:
Use the pythagorean theorem!
(think that is how you spell it )
Pythagorean theorem: a² + b² = c²
a and b are the numbers that you have in this example, c is the side you need!
75² + 40² = c²
5,625 + 1,600 = c²
7,225 = c²

(the square root and square cancel each other out)
85 = c
c = 85
