As the temperature outside increases, more people wear shorts and fewer people carry jackets. The correlation between temperature and wearing shorts is . The correlation between temperature and carrying a jacket is

Positive . ; Negative.

Step-by-step explanation:

Correlation refers to the type and strength of relationship between two variables, the type of correlation between two variables may be either negative or positive. Negative correlation exists when an increase in one variable leads to a decrease in the other while positive correlation occurs when an increase or decrease in one variable leads to a corresponding increase or decrease in the other variable.

Therefore, increase in outside temperature leads to more people wearing shorts shows a positive relationship between temperature and wearing shorts while a negative relationship exists between temperature and carrying jackets as carrying jackets decreases as outside temperature increases.

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
