The seventh-grade class needs to elect a new class president. Mary is writing an article on the election for the school paper and surveys a random selection of students about which candidate they support. The table below shows the results so far. Mary wants to survey 10 more people.

Candidate Number supporting the candidate
Julian 15
Mariana 9
Terrell 16
Denise 10
Based on the data, estimate how many of the next 10 students surveyed will support Julian.
If necessary, round your answer to the nearest whole number.

Answer 1

3

Explanation:

To estimate the number of students out of the next 10 who will support Julian, we can use the proportion of students who have supported Julian so far.

The total number of students who have been surveyed is:

15 + 9 + 16 + 10 = 50

Out of these 50 students, 15 have supported Julian. Therefore, the proportion of students who have supported Julian so far is:

15/50 = 0.3

To estimate how many of the next 10 students surveyed will support Julian, we can multiply the proportion of students who have supported Julian so far by 10:

0.3 x 10 = 3

Therefore, we can estimate that out of the next 10 students surveyed, about 3 will support Julian.
