Answer:
Step-by-step explanation:
Two boys want to balance a seesaw perfectly. One boy weighs 240 pounds and is sitting four feet from the fulcrum. The other boy weighs 160 pounds. Where should the lighter boy sit to balance the seesaw?
We solve using the formula
Distance on the fulcrum × Weight of the boy
= 4 × 240 = x × 160
4 × 240 = 160x
x = 4 × 240/169
Firstly, subtract 5 on all sides of the inequality: 
Next, multiply all sides by -1. And since you are multiplying by a <u>negative</u>, flip the signs as well. <u>Your final answer will be 
</u>
Answer:
<em><u>1.6</u></em>
Step-by-step explanation:
The Mean Absolute Deviation (MAD) is the distance each number is away from the mean divided by the amount of numbers.
15 is 4 away from 19, for example
So:
19 - 15 = 4
25 - 19 = 6
19 - 13 = 6
19 - 15 = 4
19 - 18 = 1
20 - 19 = 1
22 - 19 = 3
24 - 19 = 5
4 + 6 + 6 + 4 + 1 + 1 + 3 + 5 = 30
30/19 = 1.5789, rounded to 1.6
