Answer:
90
Step-by-step explanation:
The sum of squares of the deviation from mean=sum(x-xbar)²=?
x
12
6
15
9
18
12
xbar=sumx/n
xbar=(12+6+15+9+18+12)/6=72/6=12
x x-xbar (x-xbar)²
12 12-12=0 0
6 6-12=-6 36
15 15-12=3 9
9 9-12=-3 9
18 18-12=6 36
12 12-12=0 0
sum(x-xbar)²=0+36+9+9+36+0=90
So, the sum of squares of the deviations from the mean is 90.

Answer:
The slope would be 3.
Step-by-step explanation:
The formula for finding slope is 
We can plug these numbers into the equation by doing 
1--5 is equal to 1+5, which is 6.
2-0 is equal to 2.
is 3, which is how you get your answer.
I hope this helps! :)
Answer:
there are 34 sections at all, so you devide 10( your needed colour's number) by 34( all section number). so the answer will be 10/34
