Answer:
C. The principal randomly selects homeroom classes and surveys each student in the chosen classes.
Step-by-step explanation:
Middle school is 6-8th. Surveying only the eighth-grade students won't give a representative sample of the whole school only the eighth-graders. Option A is incorrect.
Surveying only the students in detention represents a very small amount of students compared to the school, therefore it is not a representative sample. Option B is incorrect.
Yet again, the students in the math club is a small amount of students compared to the school. It does not represent the entire, or majority of the population. Option D is incorrect.
Picking students from homeroom classes and surveying each will give a wider variation of opinions from each grade and therefore a representative sample. Option C is the correct answer.
The values of the number is 43
x+21=64
subtract 21 on each side
x = 43
50%
24 *x/100 = 12...so then 24x/100 = 12.
then x= 12 *100/24
so x =50%/
**but if u are not sure at these problems first see. that $24 she percent of it is 12 which is exactly half. So 50% off makes sense. 50%
ALSO...in math of can mean multiply..that can help u remember
