Answer to Problem 14PPS
Explanation of Solution
Given: Design a survey to give to your classmates.
The survey is for home heating.
How many houses use different types of fuels?
The data in the table form is
Then
Total number of homes
12+64+18+100+4+2=200
Now, Finding the ratio to compare number of homes to the total number of homes
12200=0.0664200=0.3218200=0.09100200=0.504200=0.022200=0.01
Now using these ratios to find the degree of each section.
0.06×360≈220.32×360≈1150.09×360≈320.50×360=1800.02×360≈70.01×360≈4
Now use the compass the protractor to draw the circle
