Question

A university has 30,330 students. In a random sample of 270 students, 18 speak three or more languages. Predict the number of students at the university who speak three or more languages.

Answer 1

Answer:

2,020 students.

Step-by-step explanation:

Let x be the numbers of students at university who speak three or more languages.

We have been given that a university has 30,330 students. In a random sample of 270 students, 18 speak three or more languages.

To find the number of students at the university who speak three or more languages, we will use proportions.

$\frac{x}{30,300}=\frac{18}{270}$

$\frac{x}{30,300}*30,300=\frac{18}{270}*30,300$

$x=\frac{18}{9}*1,010$

$x=2*1,010$

$x=2,020$

Therefore, 2,020 students at the university who speak three or more languages..
