Answer:
1
Step-by-step explanation:
The mean absolute deviation of a dataset is the average distance between each data point and the mean.
Expand
x = 150 - 0.5x
Add 0.5x to both sides
x + 0.5x = 150
Simplify x + 0.5x to 1.5x
1.5x = 150
Divide both sides by 1.5
x = 150/1.5
Simplify 150/1.5 to 100
<u>x = 100</u>
3550 cds divided by 15 cds/ rack = 236.66667
Meaning that there will be 236 full racks and the last rack will only have 10 cds

Area of square = 64cm²

Length of one side of square=?
<u>Let,</u>
side of square = x
Now,
<u>Area of square = (x)²</u>
