b. how many chose football?

Answer

First find out the  how many students participated .

As given

In a survey, a group of students were asked their favorite sport.

Eighteen students chose "other" sports.

Baseball- 40%

Football- 37.5%

Suppose that the total number of students are 100%.

Students play other sports percentage = Total percentage - Baseball percentage -Football percentage

                                                                = 100 - 40 - 37.5

                                                                = 22.5%

Formula

Here Percentage = 22.5%

Part value = 18

Put in the formula

Total value = 80

Therefore the students participated are 80.

Now find out the how many chose football .

Here  Percentage = 37.5%

Total value = 80

Put in the formula

Part value = 30

Therefore the 30 students chose football .

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b
