Students at a high school were polled to determine the type of music they preferred. there were 1950 students whocompleted the poll. their responses are represented in the circle graph. what percent of students preferred alternative music? ​

15 percent is the answer

16 + 4 = 20

16/20 = 80% or 4/5 (20 x 5 = 100, 16 x 5 = 80)

4/20 = 20% or 1/5 (20 x 5 = 100, 4 x 5 = 20)

The relationship is that more students do not prefer school uniforms compared to the ones that do prefer them. 

Hope this helps!

65/10 would be 21.6 percent

80% for class one; 58% for class two; 81% for class three.Therefore, classes one and three did his prediction hold true.

Class 1 and Class 3 shows the correct prediction that atleast 78% of students chose digital source.

Step-by-step explanation:

Since we have given that

There is a table showing number of students prefer getting their news from a digital source or a print source.

And we have mentioned that a professor predicted that at least 778 % of students prefer getting their news from digital source rather than from a print source.

From class 1, we get that

Number of students chose digital source = 20

Total number of students = 25

So, percentage of students prefer digital source is given by

Similarly, from class 2, we get that

Number of students chose digital source = 14

Total number of students = 24

So, percentage of students prefer digital source is given by

Similarly, From class 3, we get that

Number of students chose digital source = 30

Total number of students = 37

So, percentage of students prefer digital source is given by

Therefore, Class 1 and Class 3 shows the correct prediction that atleast 78% of students chose digital source.

40 (without the percent sign because the question doesn’t want you to put it)

Step-by-step explanation:

This is a very reasonable diagram because the 216˚ plus the 144˚ equal 360˚, which is sensible because a circle is 360˚ (degrees). So, you can just do 144 divided by 360 to find the percent of the circle, which equals 0.4, and 0.4 as a percent is 40%. But the question doen’t want to you to put the percent sign. So the answer is just 40.

50 percent

it takes up half of the thing

Step-by-step explanation:

65= 21.67% of 300

300=100%

65=x%

easy way is i divided 65 by 300 (.2167) and then multiplied .2167 by 100 to get the percentage. ( 21.67%)

x%= 21.67%

students preferred alternative music

= 461/1940 ×100%=23.7%

Is the sample valid?
 First you must see if the number of students in the table corresponds to the number of students surveyed that was 75.
 We have then:
 33 + 15 + 27 = 75
 We have then that:
 The sample is valid.

 what percent of students prefer caramel popcorn? 
 We can make the following rule of three to answer this question:
 75 ---> 100%
 27 ---> x
 Clearing x we have:
 x = (27/75) * (100)
 x = 36%
 36% percent of students prefer caramel popcorn
