Answer 1

Hey XD

Answer 2

D

Answer 3

heyyy lolXD

Answer 4

ooh Pegasus ;D

Answer 5

Can anyone help me with sample size?

Answer 6

its easy to check to see if it is D...just sub in your points in the inequality and see if it is true.
y - 2x <= -3 (using points (-2,3)
3 - 2(-2) <= -3
3 + 4 <= -3
7 <= -3 (this is not true)

D is not correct.
But now that you know how to do it, you can find the correct answer.

Answer 7

@texaschic101 may you please help me with finding sample size

Answer 8

I am not too good with sample size, but I can look at the problem

Answer 9

Okay. It says to find the sample size required to achieve the given margin of error.
1. +- 7%
2. +- 6%

Answer 10

I am so sorry...I do not know the sample size stuff

Answer 11

:(

Answer 12

What about normal distribution?

Answer 13

y - 2x <= -3 --- using (2,4)
4 - 2(2) <= -3
4 - 4 <= -3
0 <= -3
correct....0 is LESS then or equal to -3

answer is (2,4)

Answer 14

Here's a picture of this inequality if it helps you visualize it:

Answer 15

Thanks :) I did 1,-1 and got it wrong BUT got an 80% thanks everyone :D

Answer 16

You got it wrong??? How could you??
I'm kidding, glad you got an 80% grade. :)

Answer 17

xD I thought when it said <= and it equals the same thing I would be good but I shouldve kept working it out
