For this case we have the following inequality:
 y - 2 \ \textless \ -5&#10;
 We will solve the inequality algebraically.
 We have then:
 We add 2 to both sides of the inequality:
 y - 2 + 2 \ \textless \ -5 + 2&#10;
 Rewriting we have:
 y \ \textless \ - 3&#10;
 Therefore the solution is:
 (-inf, -3)
 Answer: 
 (-inf, -3)

The bivariate distribution of X and Y is described below: X Y 1 2 1 0.21 0.47 2 0.14 0.18 A. Find the marginal probability distr
jasenka [17]

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 = 1(0.35)+2(0.65)=1.65

Var(x) = E(x^2)-Mean ^2 = 1(0.35)+4(0.65)-1.65^2\\=2.95-2.7225\\=0.2275

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

\sqrt{7,225} = \sqrt{c}^{2}

(the square root and square cancel each other out)

85 = c

c = 85
