Well, as far as I can tell, the mean (average) is the best representation of the data because there is no outlier (a number a lot higher or lower than the rest of the numbers that throws the data off).
For digits 0 to 9

Answer:
Neither, x can be a negative number as well. If there is context, please post more to the question.
Step-by-step explanation:
Reta a:

reta x:

Retas paralelas possuem coeficientes angulares iguais ⇒ mₐ=mₓ

(-4,-2)

∴
y=3/4x+1
Answer:
a = 8
Step-by-step explanation:
x-1 = 0
x = 1
let x³ + ax² -x -8 be p(x)
hence, p(1) = (1)³ + a(1)² -1 -8 = 0 (since, x-1 is a factor)
= 1 + a - 1-8
= a - 8 = 0
therefore, a = 8
