Question

Grahamsville High School recently polled its teachers to see how many miles they drive to work each day. A stem-and-leaf plot of the results is shown below:

What percent of the teachers travel more than 38 miles to work? Rounded to the nearest whole percent.

1│1 8 9 9
2│0 0 3
3│4 6 6 7 7 8
4│0 1 2
5│5 5 6 8 9 9
6│1 2 2
4│1=41

Answer 1

To find the percentage of teachers who travel more than 38 miles to work, divide the number of teachers who travel more than 38 miles by the total number of teachers and multiply by 100.

Step-by-step explanation:

To find the percentage of teachers who travel more than 38 miles to work, we need to analyze the stem-and-leaf plot. From the plot, we can see that there are 8 teachers who travel more than 38 miles. The total number of teachers who were polled is 19. To calculate the percentage, we divide 8 by 19 and multiply by 100. So the percentage of teachers who travel more than 38 miles to work is approximately 42%.
