83 students choose to attend one of three after school activities: football, tennis or running. There are 53 boys. 36 students choose football, of which 6 are girls. 15 students choose tennis. 18 girls choose running. A student is selected at random. What is the probability this student chose running? Give your answer in its simplest form.

38.55% or 32/83

Step-by-step explanation:

First of all, we need to write down the amount of students in each activity:

Football = 36

Tennis = 15

Running = 18 girls + 14 boys (the remainder of the 83 students) so 32 students.

So 32/83 as a percentage is 38.55%

Thus, the chance of the randomly selected student being in the Running category is 38.55% or 32/83.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
