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?

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

5+2x=a
