The mean absolute deviation of the number of books is 1.84
<h3>How to determine the mean absolute deviation?</h3>
The dot plot of the number of books is in the attached figure.
From the figure, we have:
x f
1 1
2 2
3 2
4 3
5 1
6 2
7 3
8 1
Start by calculating the mean using:
So, we have:
Evaluate the sum and products
Divide
The mean absolute deviation is then calculated as:
So, we have:
Evaluate the absolute difference
Evaluate the sum of products
Divide
Hence, the mean absolute deviation of the number of books is 1.84

Step-by-step explanation:
1. Write the problem in long division format.
2. Divide 8 by 5 to get 1.
3. Multiply the quotient digit (1) by the divisor 5.
4. Subtract 5 from 8 to get 3.
5. Bring down the next number of the dividend.
6. Divide 33 by 5 to get 6.
7. Multiply the quotient digit (6) by the divisor 5.
8. Subtract 30 from 33.
9. Bring down the next number of the dividend.
10. Divide 37 by 5 to get 7
11. Multiply the quotient digit (7) by the divisor 5 .
12. Subtract 35 from 37.
13. Bring down the next number of the dividend.
14. Divide 22 by 5 to get 4
15. Multiply the quotient digit (4) by the divisor 5
16. Subtract 20 from 22.
The solution for the Long Division of 8372/5 is 1674 with a remainder of 2 or as 1674.4

Answer:
$45 with 20% markup = $45 + $9 for a new total = $54
$7.60 with a 50% markup = $7.60 + $3.80 for new total = $11.40
Step-by-step explanation:
Convert 3 4/7 into an improper fraction: 25/7
17/21 divided by 25/7
Dividing by a fraction is the same as multiplying by it's reciprocal.
17/21*7/25
Simplify:
17/3*1/25
Multiply across:
17/75
