I need help with this math please

Expectation is computed by multiplying each outcome (number of hybrids sold) by the corresponding probability, then adding these products:

0×0.32 + 1×0.28 + 2×0.15 + 3×0.11 + 4×0.08 + 5×0.06

= 1.53

So on average, 1.53 hybrids are sold each week.

the answer is. -82562234434584

step-by-step explanation:

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
