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.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

cosine
