15. A survey about the student government program at a school finds the following results:
110 students like the program.
120 students think the program is unnecessary.
210 students plan on running for student government next year.
If a circle graph were made from this data, what would the measure of the central angle be for the
group that thinks the program is unnecessary?
98º******
27º
90º
172º
Is my math right?
110+120+210=440 120/440=.27
.27*360=98
Actually, and im not sure how this is supposed to be solved, but the answer is 172.
172 is the right
It’s D
Math is crazy, lets leave it at that.
Yeah! Its D tanks!
ok sooo 172 right
For the ones who have it as "the group that likes the program" it would be
110 (students who like) / 440 (Total amount) = 25*
There are different variations of this test If you didn't notice from all the Reponses
Sure, let's solve it step-by-step:
First, we find the total number of students who participated in the survey:
Total number of students = students who like the program + students who think the program is unnecessary + students who plan on running for student government next year
Total number of students = 110 + 120 + 210 = 440
Now, we find the percentage of students who like the program:
Percentage of students who like the program = (Number of students who like the program / Total number of students who participated in the survey) x 100
Percentage of students who like the program = (110 / 440) x 100 = 25%
Finally, we find the measure of the central angle for the group that likes the program:
Measure of central angle = 25% x 360° = 90°
Therefore, the central angle for the group that likes the program is 90 degrees.
