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:
Answer:
1320
Step-by-step explanation:
We are given that
Total number of athelets are running in race=12
Total number of medals =3
We have to find the total possible number of ways can the 3 medals be distributed.
Total number of ways for choosen gold medal=12
Number of ways for choosen silver medal=11
Number of ways for choosen Bronze medal=10
Total number of possible ways=
Hence, total number of possible ways in which 3 medals be distributed=1320
Answer:
9
Step-by-step explanation:
use the formula m = y2- y1 / x2 - x1
Each crayon weighs 9 grams. First, if the box is 15 grams, you need subtract 105 with 15, which is 90. Then, divide 90 by 10(the amount of crayons), and you get 9, so each crayon weighs 9 grams
