(I NEED AN ANSWER QUICKLY! URGENT!) Emilia is doing a survey, and the question asks if it is valid. Read description.

Question

Emilia asks every fifth girl who enters school and finds that 35 of the 50 girls she surveyed like to go to the movies. There are 250 girls at her school. Is this a valid representation of the girls at Emilia's school? If yes, estimate the number of girls at school who like to go to the movies. If no, give an example of the valid representation.

Answer 1

I think it is a valid survey. 

 

35 of 50 like to go to movies

x of 250 like to go to movies

 

35/50 = x/250

 

Cross multiply you get 50X = 35*250

Divide both sides by 50 you get X = 35*5 = 175
