Question

In a sample of 40 randomly selected students at a school, 27 students eat breakfast every morning. There are 371 students in the school. Using these results, predict how many students eat breakfast.

Answer 1

To predict the number of students who eat breakfast in the whole school, we can use the ratio of students who eat breakfast in the sample to the total number of students in the school.

Step-by-step explanation:

To predict how many students eat breakfast in the school, we can use the ratio of students who eat breakfast in the sample to the total number of students in the school. In the sample of 40 students, 27 eat breakfast every morning. We can set up a proportion to find the estimated number of students who eat breakfast in the whole school:

27/40 = x/371

To solve for x, we cross-multiply and divide:

27 * 371 = 40 * x

x ≈ 245.775

Therefore, we can estimate that approximately 246 students eat breakfast in the school.
