An investor is considering a $10,000 investment in a start-up company. She estimates that she has probability 0.40 of a $12,800 loss, probability 0.26 of a $10,300 profit, probability 0.19 of a $45,000 profit, and probability 0.15 of breaking even (a profit of $0). What is the expected value of the profit? Would you advise the investor to make the investment?

gregory's graph is incorrect because it shows 2 inches of growth for each week when it should show 0.75 inches of growth each week.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

im pretty sure its
