In a random sample of 30 sixth graders, 9 have traveled outside of the United States. There are a total of 120 sixth graders in the school. Predict how many students have traveled outside of the United States?

Answer 1

To solve this problem, we can use proportions.

Let x be the number of sixth graders in the school who have traveled outside of the United States. We can set up a proportion:

9/30 = x/120

Simplifying this proportion, we get:

0.3 = x/120

To solve for x, we can cross-multiply:

0.3 * 120 = x

36 = x

Therefore, we can predict that 36 sixth graders in the school have traveled outside of the United States.
