Gloria surveyed all of the campers to determine their preferred field trip the results are displayed in the table which of the following is a relative frequency that can be found with the table round the percentage to the nearest tenth a 70% of the people who preferred mountains were 8th graders

To find the relative frequency, you need to divide the number of 8th graders who preferred mountains by the total number of campers who preferred mountains:

Number of 8th graders who preferred mountains: 70% of people who preferred mountains
Number of campers who preferred mountains: 70

Therefore, relative frequency of 8th graders who preferred mountains = (70% of 70) / 70 = (0.70 * 70) / 70 = 49 / 70 ≈ 0.7

So, the relative frequency of 8th graders who preferred mountains is approximately 0.7.
