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.
To determine the relative frequency of the percent of 7th graders who prefer mountains, we need to use the following formula:
Relative frequency = (Number of 7th graders who prefer mountains / Total number of students) * 100
So, 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 approximately 12.9%.
wrong
I apologize for the mistake. Let's correct it.
To determine the relative frequency of the percent of 7th graders who prefer mountains, we need to use the following formula:
Relative frequency = (Number of 7th graders who prefer mountains / Total number of 7th graders) * 100
From the table, we can see that 40 students in the 7th grade prefer mountains out of 110 total 7th-grade students.
Relative frequency = (40 / 110) * 100
Relative frequency = 0.3636 * 100
Relative frequency = 36.36%
Therefore, the relative frequency of the percentage of 7th graders who prefer mountains is 36.4%.
