A survey about the student government program at a school finds the following results:

110 students like the program.
120 students think the program is unnecessary.
210 students plan on running for student government next year.

If a circle graph were made from this data, what would the measure of the central angle be for the group that thinks the program is unnecessary? (1 point)

98º
27º
90º
172º

My answers:
1. mean = –28.5, median = –29.1, mode = –49, range = 40
2. 37; 20; 17.6
15. 98º

I disagree with your first answer. The other two are right.

You're welcome.

Yes, now you have the right answer for the first one.

Thank you!

You're welcome.

Thank you!

what where the answers. can you please help immediately. thank you

I need the answers to this test please hurry and give them to me

YOU ARE NOT REAL ANONYMOUS

For question 1, to find the mean, median, mode, and range of the given set of data, you can follow these steps:

1. Arrange the data in ascending order: -49, -49, -43, -39, -18, -14, -12, -9.
2. Find the mean: Add all the values together and divide by the number of values. (-49 + -49 + -43 + -39 + -18 + -14 + -12 + -9) / 8 = -28.5.
3. Find the median: If you have an odd number of values, the median is the middle value. If you have an even number of values, the median is the average of the two middle values. In this case, the median is -14.
4. Find the mode: Mode is the value that appears most frequently. In this case, the mode is -49.
5. Find the range: Subtract the smallest value from the largest value. -9 - (-49) = 40.

Therefore, the correct answer is: mean = –28.5, median = –29.1, mode = –49, range = 40.

For question 2, to identify the outlier and find the mean with and without the outlier, you can follow these steps:

1. Identify the outlier: An outlier is a value that is significantly higher or lower than the other values in the data set. In this case, the outlier is 37.
2. Find the mean with the outlier: Add all the values together and divide by the number of values. (21 + 13 + 13 + 37 + 13 + 23 + 25 + 15) / 8 = 17.6.
3. Find the mean without the outlier: Add all the values (excluding the outlier) together and divide by the number of values. (21 + 13 + 13 + 13 + 23 + 25 + 15) / 7 = 20.

Therefore, the correct answers are: a. 13; b. 37; 20; c. 17.6; 20.

For question 15, to find the measure of the central angle for the group that thinks the program is unnecessary, you can follow these steps:

1. Add up the total number of students in the survey: 110 + 120 + 210 = 440.
2. Find the proportion of students that think the program is unnecessary by dividing the number of students with that opinion by the total number of students in the survey. 120 / 440 = 0.2727.
3. Convert the proportion to a percentage by multiplying it by 100. 0.2727 * 100 = 27.27%.
4. Calculate the central angle by multiplying the percentage by 360 (since a circle is 360 degrees). 27.27% * 360 = 98.18, which can be rounded to 98 degrees.

Therefore, the correct answer is: 98º.

Okay thank you. Is the first answer "mean = –29.1, median = –28.5, mode = –49, range = 40"?
