Question

Scott polled 30 seventh graders. Twelve students said they would vote for Pedro in the upcoming election. There are 250 students who will vote in the election. How many votes do you predict Pedro will get?


A. 69 votes. B. 90 votes


C. 100 votes. D. 150 votes

Answer 1

Answer:

C. 100

Step-by-step explanation:

We can guess how many votes Pedro might get by looking at how many seventh graders support him compared to all seventh graders, and then applying that same ratio to all the voters.

Seventh graders who said they would vote for Pedro: 12

Total seventh graders polled: 30

Total votes: 250

we have to find the ratio of seventh graders who said they would vote for Pedro to the total seventh graders

$Ratio = \frac{12}{30}=0.4$

Now we have to scale this ratio to the total number of voters

$Predicted \, votes \, for \, pedro = 0.4 \, \times 250 = 100$

Pedro is predicted to get 100 votes
