hi

OpenStudy (anonymous):

hello

OpenStudy (anonymous):

can you help?

OpenStudy (anonymous):

1: Mean is the average. Add all of the numbers and divide it by the amount of numbers.

OpenStudy (anonymous):

ok 1 minet

OpenStudy (anonymous):

7, 8, 8, 8, 10, 10, 12. You have to put them in order too.

OpenStudy (anonymous):

63

OpenStudy (anonymous):

9?

OpenStudy (anonymous):

63divided by 7 = 9

OpenStudy (anonymous):

Hang on

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

Yeah thats right

OpenStudy (anonymous):

So number one would be nine, and 2 is the same deal.

OpenStudy (anonymous):

same for number 2 right

OpenStudy (anonymous):

20, 25, 28, 20. Yes.

OpenStudy (anonymous):

30 not 20

OpenStudy (anonymous):

25.75 for 2

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

So three, you have an average of 30. You have three numbers, 12, 50, 48 and a missing number.

OpenStudy (anonymous):

First, add 12 + 50 + 48

OpenStudy (anonymous):

so 3 is 10 right

OpenStudy (anonymous):

Yeah

OpenStudy (anonymous):

i have 110

OpenStudy (anonymous):

Wait

OpenStudy (anonymous):

Yes, 110 and then you would divide 30.

OpenStudy (anonymous):

Oh geez thats not right.

OpenStudy (anonymous):

?

OpenStudy (anonymous):

Nevermind I was looking at the wrong problem haha

OpenStudy (anonymous):

Yes, 10 is correct. Sorry for messing you up.

OpenStudy (anonymous):

its fine

OpenStudy (anonymous):

4 idk

OpenStudy (anonymous):

Im just gonna tell you that 4 is 1.5, because 0, 0.1 and 0.32 are all close to eachother on the number line, and that would mean that 1.5 is farther away and its an outlier

OpenStudy (anonymous):

so its 0.32

OpenStudy (anonymous):

No, its 1.5 because its farther on the number line. Here, Ill draw it out.

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

|dw:1455728594523:dw| Haha it looks terrible.
