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 0 children?

Explanation:

Step1: Identify bar - heights

From the bar - graph, the number of adults with 0 children is 4, with 1 child is 8, with 2 children is 3, and with 5 children is 2.

Step2: Calculate total number of adults

Sum up the number of adults in each category. Total = 4 + 8+3 + 2=17.

Step3: Calculate percentage of adults with 0 children

Use the formula $\text{Percentage}=\frac{\text{Number of adults with 0 children}}{\text{Total number of adults}}\times100\%$. So, $\text{Percentage}=\frac{4}{17}\times100\%\approx23.53\%$.

Answer:

How many adults were questioned: 17
What percentage of the adults questioned had 0 children: 23.53%
