Chapter SR32, Problem 11P

Solution

If you randomly selected 500 U.S. homes, about how many would be heated with fuel oil?

50 homes.

Given:

Use the circle graph to answer the exercise.

  

Concept used:

• A circle graph is a visual way of displaying data that is written in percent’s.
• The circle represents 100%. The circle is divided into sections. Each section shows what part of 100 that item represents.

Calculation:

The given circle graph is −

  

According to question if we randomly select 500 US. Homes then no. of U.S. homes heated with fuel oil −

Percent of U.S. homes heated with fuel oil = 10%

No. of U.S. homes heated with fuel oil out of total 500 U.S. homes -

  $\begin{array}{l}=10\%of500\\ =\frac{10}{100}(500)\\ =\frac{5000}{100}\\ =50\end{array}$

So, 50 homes heated with fuel oil, if we randomly selected 500 U.S. homes.
