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.
The relative frequency that can be found with the table is the percentage of students in each grade level who prefer a specific field trip option.
For the 7th grade students, the relative frequency of those who prefer the seacoast field trip would be:
(70 / 160) * 100 = 43.8%
For the 8th grade students, the relative frequency of those who prefer the seacoast field trip would be:
(90 / 150) * 100 = 60%
Therefore, the relative frequencies are 43.8% for 7th grade students and 60% for 8th grade students who prefer the seacoast field trip.

sandy soil: 120 , 50 , 170
rocky soil: 100 , 150, 250
totals: 220, 200, 420
examine the data from a survey of farmers about their different soil types and the crops they prefer to grow. using relative frequencies, what is the percentage chance that farmers with sandy soil prefer to grow carrots? round your answer to the nearest tenth.
_%
To find the percentage chance that farmers with sandy soil prefer to grow carrots, you need to calculate the relative frequency for this specific group.
The total number of farmers with sandy soil is 170 and the number of those who prefer to grow carrots is 120. The relative frequency for this group is:
(120 / 170) * 100 = 70.6%
Therefore, the percentage chance that farmers with sandy soil prefer to grow carrots is 70.6%.

sandy soil: 120 , 50 , 170
rocky soil: 100 , 150, 250
totals: 220, 200, 420
examine the data from a survey of farmers about their different soil types and the crops they prefer to grow. using relative frequencies, what is the percentage chance that farmers with rocky soil prefer growing peppers? round your answer to the nearest tenth.
To find the percentage chance that farmers with rocky soil prefer to grow peppers, you need to calculate the relative frequency for this specific group.
The total number of farmers with rocky soil is 250 and the number of those who prefer to grow peppers is 150. The relative frequency for this group is:
(150 / 250) * 100 = 60%
Therefore, the percentage chance that farmers with rocky soil prefer to grow peppers is 60%.

rocky soil: 100 , 150, 250
totals: 220, 200, 420
examine the data from a survey of farmers about their different soil types and the crops they prefer to grow. using relative frequencies, what is the percentage chance that if a farmer prefers to grow carrots they have rocky soil? round your answer to the nearest tenth.
_%
To find the percentage chance that if a farmer prefers to grow carrots, they have rocky soil, you need to calculate the relative frequency for this specific scenario.
The total number of farmers who prefer to grow carrots is 220. Among them, the number of farmers with rocky soil is 100. The relative frequency for this scenario is:
(100 / 220) * 100 = 45.5%
Therefore, the percentage chance that if a farmer prefers to grow carrots, they have rocky soil is 45.5%.
