Step-by-step explanation:
We have the following data given:
62 63 68 72 79 80 83 93 94 95
And we need to begin finding the mean with the following formula:
![\bar X = \frac{\sum_{i=1}^n X_i}{n}](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%3D%20%5Cfrac%7B%5Csum_%7Bi%3D1%7D%5En%20X_i%7D%7Bn%7D)
And replacing we got:
![\bar X = \frac{62+63+68+72+79+80+83+93+94+95}{10}= 78.9](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%3D%20%5Cfrac%7B62%2B63%2B68%2B72%2B79%2B80%2B83%2B93%2B94%2B95%7D%7B10%7D%3D%2078.9)
Now we can find the mean absolute deviation like this:
![|62-78.9| = 16.9](https://tex.z-dn.net/?f=%20%7C62-78.9%7C%20%3D%2016.9)
![|63-78.9| = 15.9](https://tex.z-dn.net/?f=%20%7C63-78.9%7C%20%3D%2015.9)
![|68-78.9| = 10.9](https://tex.z-dn.net/?f=%20%7C68-78.9%7C%20%3D%2010.9)
![|72-78.9| = 6.9](https://tex.z-dn.net/?f=%20%7C72-78.9%7C%20%3D%206.9)
![|79-78.9| = 0.1](https://tex.z-dn.net/?f=%20%7C79-78.9%7C%20%3D%200.1)
![|80-78.9| = 1.1](https://tex.z-dn.net/?f=%20%7C80-78.9%7C%20%3D%201.1)
![|83-78.9| = 4.1](https://tex.z-dn.net/?f=%20%7C83-78.9%7C%20%3D%204.1)
![|93-78.9| = 14.1](https://tex.z-dn.net/?f=%20%7C93-78.9%7C%20%3D%2014.1)
![|94-78.9| = 15.1](https://tex.z-dn.net/?f=%20%7C94-78.9%7C%20%3D%2015.1)
![|95-78.9| = 16.1](https://tex.z-dn.net/?f=%20%7C95-78.9%7C%20%3D%2016.1)
And finally we can find the mean abslute deviation with the following formula:
![MAD = \frac{\sum_{i=1}^n |X_i -\bar X|}{n}](https://tex.z-dn.net/?f=%20MAD%20%3D%20%5Cfrac%7B%5Csum_%7Bi%3D1%7D%5En%20%7CX_i%20-%5Cbar%20X%7C%7D%7Bn%7D)
And replacing we got:
![MAD =\frac{16.9+15.9+10.9+6.9+0.1+1.1+4.1+14.1+15.1+16.1}{10}= 10.12](https://tex.z-dn.net/?f=%20MAD%20%3D%5Cfrac%7B16.9%2B15.9%2B10.9%2B6.9%2B0.1%2B1.1%2B4.1%2B14.1%2B15.1%2B16.1%7D%7B10%7D%3D%2010.12)

From the information you gave me, I am going to guess it is a 4 pack of highlighters.
Answer: $0.60 per highlighter
Explanation: To find the unit rate of an item, take the price ($2.40) and divide it by the amount of the product included (4).
the answer to that question is 6000
Answer:
108ft³
Step-by-step explanation:
V=(base area) (h/3) = 81 (4
/3) =108ft³
Answer:
She will pay $122.85
Step-by-step explanation:
First, find the amount of the percents.
To do that, turn the percents into decimals.
25% --> 0.25
10% --> 0.10
Then, multiply each decimal with the original price.
189×0.25= 47.25
189×0.10= 18.90
Now that you have the amount of the percents, subtract both from the original price.
189- (47.25+18.90)
189-66.15= 122.85
