Which list shows all the factor pairs of 72? a. 1 and 72, 2 and 36, 3 and 24, 6 and 12, 8 and 9 b. 1 and 72, 2 and 36, 3 and 24, 4 and 18, 6 and 12, 8 and 9 c. 1 and 72, 2 and 36, 3 and 24, 4 and 13, 6 and 12, 8 and 9 d. 1 and 72, 2 and 36, 3 and 24, 4 and 18, 6 and 12, 7 and 9

The answer is C

Step-by-step explanation:

Faxx

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
