Answer
The normal cost would be $11.50
Number Explanation
1) 76 ÷ 8 = 9.5
2) 9.5 + 2 = 11.5 or 11.50
Word Explanation
First, I divided the total cost 76 by the number of people 8, to find out how much it costs per person. I got 9.5! Next, I added 2 to 9.5 because in the problem it said this is $2 less than the normal cost per person. I got 11.5! That was my answer.
No they would be intersecting. x=-1 is a vertical line down the x axis on -1. y=2 is a horizontal line at 2 on the y axis.
Answer:
17.02
Step-by-step explanation:
Calculation for What is the variance of the stock's returns
First step is to calculate the E(R) Expected return
E(R) = .29(−0.115) + .32(0.02) + .39(0.252)
E(R) = .0713*100
E(R)=7.13%
Now let calculate the variance
σ2 = .29(−0.115 −0.0713.)^2 + 32(0.02−0.0713 )^2 + .39(0.252 −0.0713 )^2
σ2 = .1702*100
σ2=17.02%
Therefore the variance of the stock's returns will be 17.02%
