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..
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.
HEY ANYONE EVER THINK ABOUT THE SCHOOL YOUR IN AND THE TEST ANSWERS ARE DIFFERENT just sayin
dont submit answers if they are not right its not funny
I got 7/17 from Ms Sue Answers
oh my god! i freaking failed! no! isnt mrs sue supposed to help!?
Random Person I just FAILED MY test!!!! Screw you!
**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
