The correct answers are four and four (4,4).
Why? Since Nettie was able to produce 8 cupcakes and 4 hamburgers within an hour, which gives her 8 cupcakes and 4 hamburgers available for trading while Becky was able to produce 4 cupcakes and 8 hamburgers in an hour. When they traded each other for a certain food its value will be equal to the opposite food, like 1 hamburger is equivalent to 1 cupcake, Nettie consumed 4 hamburgers, while Becky consumed 4 cupcakes, which is why they both consumed 4 pieces of food each after their trade.
Answer:
Expected rate of return on stock is 14.86%
Explanation:
The expected rate of return of a stock is the mean return that is expected to be earned by the stock considering the different scenarios that can occur, the return in these scenarios and the probability of the occurrence of these scenarios. The formula for expected rate of return of stock is,
rE = pA * rA + pB * rB + ... + pN * rN
Where,
- pA, pB, ... represents the probability that scenario A, B and so on will occur or the probability of each scenario
- rA, rB, ... represents the return in scenario A, B and so on
rE = 0.21 * 0.2 + 0.72 * 0.15 + 0.07 * -0.02
rE = 0.1486 or 14.86%

Answer:
Amount of money invested is $2,000 and $4,000
Explanation:
In this question, we are asked to calculate how much was invested in two different accounts given the amount of money invested in both accounts.
Let the amount of money invested in both accounts be a and b respectively.
Mathematically;
A + B = 6000 ......I
Now we use the formula for simple interest to check the amount that is supposed to be made on Both accounts if he end of a year.
Formula for simple interest is I = PRT/100
Let’s apply this to what is on ground:
5*1* a/100 = 5a/100
Second is
9*b*1/100 = 9b/100
That is 5a + 9b = 38,000. ........ii
Solving Both simultaneously as follows:
Let A = 6000-b from 1
Substitute this into 2
5(6000-b) + 9b = 38,000
30,000 -5b + 9b = 38,000
4b = 8,000
b =$2000
This means a would be 6000 - 2,000 = $4000
