Answer 1

Answer 2

First step. Find the coords of every single point on that graph

Answer 3

Okay....

Answer 4

(10,1) (1,2) (4,3) (9,5) (5,6) (3,6) (8,7) (6,7) (7,10) (2,10)

Answer 5

Right?

Answer 6

yep. next step.
notice how Vraiable B is on the y-axis? Now list all the y-coords

Answer 7

Hmmmm um how?

Answer 8

I'm not the best at math lol so excuse me if i take awhile to get things xD

Answer 9

coords are composed like this
(x-value, y-value)

Answer 10

sorry, i meant y-value before. not y-coord

Answer 11

Ohhhhh

Answer 12

Answer 13

@jagr2713

Answer 14

so...list all the y-values from the coords

Answer 15

Hmmmm okay 1 second

Answer 16

wouldn't it just be the first number of what i have listed?

Answer 17

??

Answer 18

no. you have to find the mean of all the values of Varible B, which is the y-values

Answer 19

Omg i dont get this at all :\

Answer 20

I'm sorry I wasted your time o.o

Answer 21

You're not wasting my time. Here I'll show you

Answer 22

Okay :\ thanks

Answer 23

So, all the y-values from the coords are 1,2, 3, 4, 5, 6, 7, 8, 9, 10, hilariously enough

Answer 24

To find the mean, aka, average, add them up, then divide the amount of numbers (which is 10)
\(\Large\frac{1+2+3+4+5+6+7+8+9+10}{10}=\frac{55}{10}=5.5\)

Answer 25

Omg din't i feel stupid :\

Answer 26

Don't feel stupid. I wasn't explaining it good.

Answer 27

Don't wow xD

Answer 28

I have a few more the next one is on range now i suck at this so it may take awhile but if you cant help i understand no worries xD

Answer 29

range is just the maximum minus the minimum
