In a survey, a group of students were all asked their favorite sport. eighteen students chose "other" sports. how many students participate? how many chose football?

The complete question

In a survey, a group of students were asked their favorite sport. eighteen students chose “other” sports, while 37.5% chose football, and 40% chose baseball. how many students chose football

Number of student that chose football = 30

Step-by-step explanation:

In a survey student were asked to choose their favorite sports.

The number of student that chose other sport = 18

The percentage number of students that chose football = 37.5%

The percentage number of students that chose baseball = 40%

The whole number of student survey = 100%

percentage number of student that chose other sport = 100% - 37.5% - 40%

percentage number of student that chose other sport =  22.5%

The total number of student surveyed can be computed as

Let the total number of student surveyed = a

22.5/100 × a = 18

22.5a/100 = 18

cross multiply

22.5a = 1800

a = 1800/22.5

a = 80

The number of student that chose football can be computed since the total number of student surveyed is known

Number of student that chose football = 37.5/100 × 80

Number of student that chose football = 3000 /100

Number of student that chose football = 30

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

the answer is 13/48
