Answer 1

To determine the relative frequency of 7th graders who prefer mountains, you divide the number of 7th graders who prefer mountains by the total number of students surveyed:

Relative Frequency = (Number of 7th graders who prefer mountains / Total number of students surveyed) * 100

Relative Frequency = (40 / 310) * 100
Relative Frequency = 0.129 * 100
Relative Frequency = 12.9%

Therefore, the relative frequency of the percent of 7th graders who prefer mountains is 12.9%.

Answer 2

Answer 3

I apologize for the error. Let's correct that:

To determine the relative frequency of 7th graders who prefer mountains, you divide the number of 7th graders who prefer mountains by the total number of 7th graders:

Relative Frequency = (Number of 7th graders who prefer mountains / Total number of 7th graders) * 100

Relative Frequency = (40 / 110) * 100
Relative Frequency = 0.3636 * 100
Relative Frequency = 36.4%

Therefore, the relative frequency of the percent of 7th graders who prefer mountains is 36.4%.
