C

bereason 28 students who are in 12th grade that play 2 or more sports separated by the complete 612 students to make a ratio

9%

Step-by-step explanation:

Tright here are 612 students at all and 55 of them are in the nine grade and do not play a sport. Therefore,

612 students - 100%,

55 students - x%.

You are watching: The student body at a high school was surveyed about sports participation

Mathematically, you deserve to write a proportion:

Im doing this question rn and also I think the answer must be C) the ratio of the student body that are in 12th grade and also play two or more sporting activities.

Step-by-step explanation: I made a decision this bc tright here are 28 12th graders that play 2 or even more sporting activities and also the complete student body is 612. So 28/612 makes the majority of feeling to me. Sorry this is so late but I simply checked and also it’s right!

Marginal frequency:

The number in the end column or row - "Total".

Joint frequency:

The proportion of the frequency in a particular category and the total variety of information values.

Basically, the values that aren"t in the last row or column - "Total".

The number of students that are in 9th grade and play two or more sports is a joint frequency.

This is just asking for the students in 9th grade who play 2 or even more sporting activities.

The number of students that are in the 11th grade is a marginal frequency.

This is asking for the full number of students in 11th grade.

The percent of the student body that plays one sport is a marginal loved one frequency".

This is asking for the full variety of students that play 1 sport.

The percentage of the student body that are in 12th grade and also carry out not play a sport is a joint family member frequency.

This is just asking for the students in 12th grade and also don"t play sporting activities.

Okay, according to the graph, there are 55 nine graders under the column

"NO SPORTS"

and also tbelow are 612 total people in the school

55 / 612 = the percentage of the student body that is in ninth grade and doesn"t play a sport

55 / 612 = 0.0898

8.9% yet we have to round

the answer is : around 9% of the students body

The answer is D on edge
