Answer:
- 34.3
- -4.3
- 17.7 as ... is 12 mpg
Step-by-step explanation:
Put the horsepower into the formula to see the predicted mileage. The residual is the difference between the actual and predicted. When calculations are repetitive, a calculator or spreadsheet is a useful tool.
__
A. predicted: 34.3
residual, -4.3
__
B. residual: 17.7
the residual for this car would be: 17.7 as the actual gas mileage recorded is 12 mpg
<h3>Answer: 720</h3>
============================================================
Explanation:
The number 8 from "8 year old boy" can be completely ignored. In my opinion, this is an (un)intentional distraction on your teacher's part.
There are 6 toys to arrange. The order is important.
- For the first slot, there are 6 choices.
- Then the second slot has 5 choices (we cannot have a toy occupy more than one slot at a time).
- The third slot has 4 choices, and so on.
We have this countdown: 6,5,4,3,2,1
Those values multiply out to 6*5*4*3*2*1 = 720
There are 720 ways to arrange the 6 different toys. Order matters.
---------------------
An alternative approach is to use the nPr permutation formula with n = 6 and r = 6. We use a permutation because order matters.
The nPr formula is
where the exclamation marks indicate factorial. For example, 6! = 6*5*4*3*2*1 = 720.
You put the line in the middle of all the points. Example above
