Answer 3

Still Ms. Smith.. :P

Answer 4

D: I got proof practices to do and it's much harder than this

Answer 5

@UsukiDoll if you know how to do it please help me? I don't know how to this and I have to send in work this week that's a 65% or i'll get dropped out of my class.

Answer 6

Mrs. Smith needs a new person because I'm trying to prove that (A+B)+b = A

Answer 7

I'm not Mrs. Smith Mrs. Smith is the woman in the problem but I don't understand what they mean by "how the values for Classes A and B vary about the mean and median."

Answer 8

I am solving A for you..
mean(A) = 79
median(A) = 85

How numbers vary about the mean and median?
Higher frequency of numbers with magnitude > mean

Answer 9

Also,
more deviation in numbers with magnitude < mean

@lolloveyou
Can you explain my conclusions ??

Answer 11

Yes. Thank you I knew the Mean for A was 79 and the median for A is 85 I wrote that and the mean for B is 85.13 and the median for B is 86. and thank you for telling me how the numbers vary but what information does that give Mrs. Smith?

Answer 12

OH.Thank you.

Answer 13

It's hard to predict what women can extract from any innocent data..:P

Answer 14

Where did intersection and union came from ??

Answer 15

Can you tell me how the numbers vary about mean and median for B ??

Answer 16

@UsukiDoll
I mean..how are they related to the question ?

Answer 17

oh sorry...hijacked the thread :(

Answer 18

Was that an accident?

Answer 19

Answer 20

The median is 86 and the mean is 85.13 thats how they vary

Answer 21

You really got out of hand.

Answer 22

@lolloveyou
For the part related to Ms Smith...I'll need to see the complete question..

Answer 23

that was the complete question but I think I figured it out thank you.

Answer 24

:)

Answer 25

When the median and mean are near the same, it means you have a lot of balance between people below and above the average.

If the median is lower than average, then that means there are good students increasing the mean while most students are actually below it.

If the median is higher, then you have a few bad students really holding down the mean.
