Melanie asked 15 random seventh-grade students how many soccer games they attended this school year. the number of games attended by each student is listed below. 2, 3, 6, 4, 7, 0, 4, 5, 0, 1, 2, 3, 2, 1, 4 what is the ratio of the total number of surveyed students who attended soccer games to the total number of students surveyed?

13:15

Step-by-step explanation:

Given: Melanie asked 15 random seventh-grade students how many soccer games they attended this school year. The number of games attended by each student is listed below. 2, 3, 6, 4, 7, 0, 4, 5, 0, 1, 2, 3, 2, 1, 4

Here , the number of students who did not attendgames=2   [since there are 2 0s]

The total number of students = 15

The number of students who attend games= 15-2=13

Now, the ratio of the the total number of surveyed students who attended soccer games to the total number of students surveyed is given by 13:15

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
