what are the mean median mode and range of the data set give the altitude of lake in feet: -12,-9,-14,-39-49,-49,-18, and -43?

A. mean=-28.5, median=-29.1, mode=-49, range=40

B. mean=-29.1, median=-49 , mode=-28.5 , range= 41

C. mean=-49 , median=-29.1, mode=-28.5 , range=41

D. mean=-29.1, median=-28.5, mode=-49, range=40

I think D or C..

1. I get a different mean than any of those answers. However, the mode makes only one of those answers correct.

3. **ANSWER: Mean = –28.5, median = –29.1, mode = –49, range = 40

First put them in order
- 49, - 49 , - 43 , -39 , -18, -14, -12, -9
Add the two middle numbers -39 and -18, it equals -57
Divide - 57 and 2, it equals - 28.5 <--- MEAN

Second add all the numbers together, it equals - 233, then divide by 8, which equals
- 29.1 <---MEDIAN

MODE is the number that happens most, which is -49 <--- MODE

The range is -49 - ( -9 ) = - 40 <-----RANGE

19.) Mr. Green teaches band, choir, and math. This year, he has 57 students that take at least one of his classes. He teaches band to 25 students. There are 9 students who have Mr. Green for math and nothing else. Use the Venn diagram below: How many students take exactly 2 classes with Mr. Green?

Answer: 26 students take exactly 2 classes check the work below.
25 - ( 7 + 3 + 11) Use order of operations or pemdas
25 - ( 21 ) = 4 ** students who take both Band and Choir

Add 11 + 7 + 3 + 4 + 17 + 9 = 51

Subtract 57 - 42 = 15***Students take Math and Choir

Add 15 + 4 + 7 , these are the sections in the Venn Diagram where two circles share the same space.

15 + 4 + 7 = 26 ***** ANSWER

26 students take exactly two classes.

25. People, please chill out! Also, don't use answers on here for tests. Here are a few reasons why:

A) There are MANY different versions of the math test. Most people get a different version. The teachers do that so people can't cheat. (The questions are the same type, just with different numbers. Also, the first question is always the same thing because they don't want you to suspect anything).

B) Some people purposely put the wrong answers on here; so watch out! Also, people like to impersonate the people who work here (Like Ms. Sue).

C) ALWAYS check your answers! There is a very slim chance that you will have the same test as someone, but if you still do and they "got a 100," still check the answers. They could still be wrong or who knows, you may have a couple different questions since the questions get randomized.

I hope this helped you a little bit! (Btw, this doesn't just go for math, apply this to whenever someone is "giving you answers," even if they are your friend.
