At the beginning of the school year, 70 students signed up for music lessons. Students could choose drums, guitar, piano, or vio
Irina18 [472]

Answer:

D.

Step-by-step explanation:

1. Answer A:

15 students signed up for violin lessons (4 boys + 11 girls)

15 / 70 = approx. 21% of the class.

Answer A says 28%, so this is incorrect.

2. Answer B:

17 students signed up for drum lessons (11 boys + 6 girls)

17/70 = approx. 24%

B says 17% signed up for drums, so this is incorrect.

3. Answer C.

Wrong because more girls signed up for piano lessons (15 girls, whereas only 9 boys signed up for piano)

4. D. The same percent of boys and girls are taking guitar lessons.

Get the total number of boys and girls in the class (just add the results for each separately for all instruments)

Boys: 11 + 6 + 9 + 4 = 30

Girls: 6+8+15+11 = 40

6 out of 30 boys signed up for guitar

6/30= 20%

8 out of 40 girls signed up for guitar

8/40 = 20%

Answer is D

In a survey of 120 8th graders, 84 liked math, 73 liked science and 23 liked math but not science. how many students disliked bo

24  
We can divide the 8th graders into 4 groups. They are: 
1. Like both math and science. 
2. Like only math. 
3. Like only science. 
4. Don't like either math or science.  
The sum of the people in all 4 groups will add up to 120. So let's see how many are in each group. 
We've been given 23 as the number of people who like only math (group 2).
And since we know that 84 people like math, that means that 84 - 23 = 61 people are in group 1. And since we know that 73 people like science, that means that 73 - 61 = 12 are in group 3. So of the 4 groups, we now know. 
1. Like both math and science (61 people).
 2. Like only math (23 people).
 3. Like only science (12 people).
 4. Don't like either math or science (unknown).
 
 So for the people left in group 4 (don't like either subject) that will be 120 - 61 - 23 - 12 = 24.
