An investor is considering a $10,000 investment in a start-up company. she es; mates that she has probability 0.25 of a $20,000 loss, probability 0.20 of a $10,000 profit, probability 0.15 of a $50,000 profit, and probability 0.40 of breaking even (a profit of $0). what is the expected value of the profit? would you advise the investor to make the investment?

The expected value of profit is 4,500$ and I would advise the investor to make the investment.

Step-by-step explanation:

Used Terminologies:

In general, the expected profit is calculated by using following equation:

E(Profit_x) = (Probability of x) * (Profit in x scenario)

E(Profit) = Total Expected Profit = Sum of expected profits from all possible outcomes

E(Profit_A) = Expected Profit against possible outcome A.

E(Profit_B) = Expected Profit against possible outcome B.

E(Profit_C) = Expected Profit against possible outcome C.

E(Profit_D) = Expected Profit against possible outcome D.

We have 4 possible outcomes with 4 different possibilities as under:

Possible Outcome 1 (A):  She has 0.25 probability of 20,000$ profit

E(Profit_A) = (Probability of A) * (Profit from scenario A)

E(Profit_A) = 0.25 * (-20,000)

E(Profit_A) = -5,000$

Similarly we have from Possible Outcomes 2(B) , 3(C) & 4(D) as under respectively:

E(Profit_B) = 0.2 * (10,000)

E(Profit_B) = 2,000$

E(Profit_C) = 0.15 * 50,000

E(Profit_C) = 7,500$

E(Profit_D) = 0.4 * 0

E(Profit_D) = 0$

Therefore we have total expected profit from the investment as:

E(Profit) = E(Profit_A) + E(Profit_B) + E(Profit_C) + E(Profit_D)

E(Profit) = -5000 + 2000 + 7500 + 0

E(Profit) = 4,500$

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

copy and paste, put it in google

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
