Please help me I am dum b Evaluate each expression for g = -7 and h = 3 and match it to its value.

1. gh

10

2. g2 - h

2

3. g + h2

-21

4. g + h

-10

5. h - g

46

6. g - h

-4

Answers:

1. gh = -21

2. g^2 - h = 46

3. g + h^2 = 2

4. g + h = -4

5. h - g = 10

6. g - h = -10

Step-by-step explanation:

1. -7 x 3 = -21

2. -7^2 = - 49

-49 + 3 = -46

3. 3^2 = 9

-7 + 9 = 2

4. -7 + 3 = -4

5. 3 - -7 = 3 + 7 = 10

6. -7 - 3 = -10

the expected value of the random variable : 0, 1 and 2
