Question

A neighborhood is trying to set up school carpools, but they need to determine the number of students that need to travel to the elementary school (ages 5-10), the middle school (ages 11-13), and the high school (ages 14-18). A bar chart summarizes their findings: Bar chart titled Carpool, with Number of Children on the y axis and Schools Groups on the x axis. Bar 1 is Elementary School ages 5 to 10 and has a value of 7. Bar 2 is Middle School ages 11 to 13 and has a value of 5. Bar 3 is High School ages 14 to 18 and has a value of 4. Which of the following data sets is represented in the bar chart? {15, 6, 7, 16, 11, 13, 8, 9, 12, 14, 14, 12, 11, 5, 10, 10} {7, 7, 7, 7, 7, 7, 7, 5, 5, 5, 5, 5, 4, 4, 4, 4} {5, 7, 10, 5, 11, 13, 4, 14, 18} {5, 6, 7, 8, 14, 18, 16, 17, 11, 12, 13}

Answer 1

The correct dataset that matches the bar chart values for the number of students traveling to different schools is {7, 7, 7, 7, 7, 7, 7, 5, 5, 5, 5, 5, 4, 4, 4, 4}.

Step-by-step explanation:

The question asks us to identify the dataset represented in a bar chart that summarizes the number of students needing to travel to elementary, middle, and high school, with values of 7, 5, and 4, respectively.

After analyzing the provided datasets, the correct dataset that matches the values on the bar chart is the second option: {7, 7, 7, 7, 7, 7, 7, 5, 5, 5, 5, 5, 4, 4, 4, 4}. This dataset corresponds to 7 students for the elementary school (ages 5-10), 5 students for the middle school (ages 11-13), and 4 students for the high school (ages 14-18).

The data set represented in the bar chart is: {7, 7, 7, 7, 7, 7, 7, 5, 5, 5, 5, 5, 4, 4, 4, 4}. This is because the bar chart shows that there are 7 students in the Elementary School age group, 5 students in the Middle School age group, and 4 students in the High School age group.
