In farming, the relationship between precipitation during the growing season and crop yield is quadratic. The following table shows the amount of rainfall (in inches) with corresponding soybean crop yields (in bushels per acre) for an agricultural region. Rainfall Crop Yield
2.25 42.1
2.75 43.0
3.25 43.8
3.75 44.2
4.25 44.5
4.75 44.3
5.25 43.5
Use a quadratic regression calculator to write a quadratic function that provides a reasonable fit to this set of data.

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
