To determine the relative frequency of the percent of 7th graders who prefer mountains, we look at the number of 7th graders who prefer mountains (40) divided by the total number of students (310) and then multiply by 100 to get the percentage:
(40/310) * 100 = 12.9%
Rounding to the nearest tenth, the relative frequency of 7th graders who prefer mountains is 12.9%.
Therefore, none of the given options is correct.
Use the table to answer the question.
Students Seacoast Mountains Totals
7th Grade 70 40 110
8th Grade 90 110 200
Totals 160 150 310
Determine the relative frequency of the percent of 7th graders who prefer mountains. Round the percentage to the nearest tenth.

Your an idiot, incorrect! try again, and pick the correct option!
My apologies, let's try this again.
The relative frequency of the percent of 7th graders who prefer mountains can be calculated by dividing the number of 7th graders who prefer mountains (40) by the total number of 7th graders (110), and then multiplying by 100 to get the percentage:
(40/110) * 100 = 36.4%
Rounded to the nearest tenth, the relative frequency of 7th graders who prefer mountains is 36.4%.
Therefore, the correct option is:
36.4%
