A local library manager randomly surveys 80 patrons about the type of book they borrow when they visit the library. The manager finds that 3 patrons borrow novels.

Answer 1

To find the approximate number of patrons who borrow novels, we can set up a proportion using the information given in the survey.

3 patrons borrow novels out of a sample of 80 patrons surveyed.

So, the proportion can be set up as:
3/80 = x/345

Cross multiplying, we get:
80x = 3 * 345
80x = 1035
x = 1035/80
x ≈ 12.94

Rounding to the nearest whole number, approximately 13 out of the 345 patrons borrow novels when they visit the library.
