Answer:
the x² test statistic 13.71
Option a) 13.71 is the correct answer.
Step-by-step explanation:
Given the data in the question;
Feeder 1 2 3 4
Observed visits; 
60 90 92 58
data sample = 300
Expected 
= 300 / 4 = 75
the x² test statistic = ?
= ∑[ ( - )²/]
= [ (60 - 75)² / 75 ] + [ (90 - 75)² / 75 ] + [ (92 - 75)² / 75 ] + [ (58 - 75)² / 75 ]
= [ 3 ] + [ 3 ] + [ 3.8533 ] + [ 3.8533 ]
= 13.7066 ≈ 13.71
Therefore, the x² test statistic 13.71
Option a) 13.71 is the correct answer.
In order to find out what deal is better:
- We have to find the unit rate for each deal
- Total amount of paper towels ÷ The price
So it would be....
- 18 ÷ 14 = 1.285714
- 12 ÷ 10 = 1.2
Short Answer:
The better deal is 10 rolls of paper towels for $12.
Long Answer:
I wanted to find out the price per roll of paper towel for each deal so I created a unit rate problem which is the numerator divided by the denominator. From there, I was able to get my answers, compare which one was less than the other, and select the best deal.

Answer:
Step-by-step explanation:
The equation given is:
We take d's to one side and others to another side of the equal sign. Thus,
<u>Note:</u> remembering to change signs when changing sides
Now, we want to isolate d on the RHS:
To make "d" the subject, we divide both sides by "m+6", to get our answer:
This is the answer.
