Question

the graph below represents how long it takes students in an 8th grade math class to get to school every morning. commute time bar graph with x-axis: minutes (0-9, 10-19, 20-29, 30-39, 40-49, 50-59), y-axis: frequency (number of students) with bars: 0-9: 3, 10-19: 7, 20-29: 4, 30-39: 3, 40-49: 3, 50-59: 4 what was the most common interval of commute times? deltamath.com

Explanation:

Step1: Identify the tallest bar

In a frequency bar graph, the tallest bar represents the interval with the highest frequency (most common).
Looking at the graph, the bar for the interval 10 - 19 minutes has a height of 7, which is the tallest among all bars.

Step2: Confirm the interval

Check the x - axis label for the tallest bar. The tallest bar corresponds to the 10 - 19 minutes interval.

Answer:

10 - 19 minutes
