To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean
18/27x100
66.6667 percent increase for the 3 years
22.2223 percent increase per year
Step-by-step explanation :
First, you have to find the area of the rectangular swimming pool (A1), which has <span>10 feet long and 6 feet wide. The area of a rectangle is:
A=A1=LxW
L=10 ft
W=6 ft
When you substitute these values into the formula, you obtain:
</span>
A1=LxW
A1=(10 ft)(6ft)
A1=60 ft²
The area of the Andrea’s backyard (A2) is 400 ft², therefore, the<span> area of Andrea’s backyard, not including the swimming pool (A3), is:
A3=A2-A1
A3=400 ft</span>²-60 ft²
A3=340 ft²
<span>
What is the area of Andrea’s backyard, not including the swimming pool?
The answer is: T</span>he area of Andrea’s backyard, not including the swimming pool, is 340 feet²
