Question

What are the mean, median mode and range of the data we given the altitude of lakes in feet?
-9,-36,-23,-8,17,-52,27,-36
Mean: -25 Median: -26 mode: -44 range: 36
Mean: -25 Median: -:-36 mode: -36 Range: 44
Mean: -26 Median: -25 Mode: -36 range: 44
Mean: -26 Median: -44 Mode: -25 Range: 36

Can someone help? I keep getting
Mean: -13
Mode: -36
Median: -20
Range: 88

Answer 1

Are you sure that's all the data and that you typed that data in correctly?

I haven't thrown this into my calculator, but just by observation, the range would be 27 - -52 = 79? None of those choices are correct if that's your complete data...

(If you have to pick, I'd at least guess between the mode of -36.)

Answer 2

ANSWER: mean = –25; median = –26; mode = –44; range = 36

Put them in order
-52, - 36, -36, -27, -23, -17, -9, -8

Select the two numbers in the middle - 27 and - 23,
- 27 + ( -23) = - 50
Divide -50 and 2
-50 / 2 = - 25 <---- MEAN

To find the Median, add all the numbers
-52 + - 36 + -36 + -27 + -23 + -17 + -9 + -8 = 208

Divide 208 and 8
-208 / 8 = - 26 <---- MEDIAN

I think you can figure out the Range and Mode yourself. Good luck

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.
