The number of goals scored by a hockey
team in each of its first 10 games is 2, 4,0,3,
4, 1, 3, 1, 1, and 5. find the mean absolute deviation of the number of goals scored

Hello!

Mean Absolute Deviation: 1.4

Mean:

Add them together then divide by the amount of numbers in the data set:

2 + 4 + 0 + 3 + 4 + 1 + 3 + 1 + 1 + 5 = 24

24 ÷ 10 = 2.4

Absolute Deviation:

Find the distance of each value from the mean:

2 - 0.4

4 - 1.6

0 - 2.4

3 - 0.6

4 - 1.6

1 - 1.4

3 - 0.6

1 - 1.4

1 - 1.4

5 - 2.6

Now, add these new numbers up at divide by 10:

0.4 + 1.6 + 2.4 + 0.6 + 1.6 + 1.4 + 0.6 + 1.4 + 1.4 + 2.6 = 14

14 ÷ 10 = 1.4

Have a good day!

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
