Question

a group of adults were asked how many children they have in their families. the bar graph below shows the number of adults who indicated each number of children. how many adults were questioned? what percentage of the adults questioned had 2 children? (round the percent to two decimal places as needed.)

Explanation:

Step1: Calculate total number of adults

Sum the number of adults for each number of children.
$$2 + 8+2 + 1+2=15$$

Step2: Calculate percentage for 2 children

Number of adults with 2 children is 2. Use formula $\text{Percentage}=\frac{\text{Part}}{\text{Whole}}\times100$.
$$\frac{2}{15}\times 100=\frac{200}{15}\approx13.33$$

Answer:

15
13.33%
