Given the altitude of lakes in feet: –12, –9, –14, –39, –49, –49, –18, –43, find the mean, median, mode, and range.
(1 point)
mean = –28.5, median = –29.1, mode = –49, range = 40
mean = –29.1, median = –49, mode = –28.5, range = 41
mean = –49, median = –29.1, mode = –28.5, range = 41
mean = –29.1, median = –28.5, mode = –49, range = 40

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.

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

You're welcome.
Yes, now you have the right answer for the first one.
