Carly surveyed 30 students in her class to find the type of music they preferred the results are shown in the chart Carly is riding a news article about the survey for the school paper she wants to show the results in fraction form what fraction of the class preferred rock music

3/5

Step-by-step explanation:

Fractions can be written as:

part/whole

In this case, the part is the number who prefer rock music and the whole is the total number of students in the class.

We know, from the table, that 18 students prefer rock music. We also know, from the information above the table, that there are 30 students in the class. Therefore,

part=18 students

whole=30 students

part/whole

18 students /30 students

18/30

This fraction can be simplified. Both the numerator (top number) and denominator (bottom number) can be divided by 6.

18/6 / 30/6

3/ 30/6

3/5

3/5 of the class preferred rock music, and the second choice is correct.

whats the question?

step-by-step explanation:

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.
