well, to do this we first need to find the mean of all values.
we need to find the distance of each value from that mean (subtract the mean from each value, ignore minus signs)
Then find the mean of those distances.
so, after we do all of that with the given numbers, our final result would be 2.333333333..... (It goes on) we round it up to 2.3, and viola! the answer is C.

Answer:
11
Step-by-step explanation:
4 × (2 3/4) = 4×2 + 4×(3/4) = 8 + 3 = 11
or
4 × (2 3/4) = 4 × 11/4 = 11
Easy
a quadatic is 2n degree
the roots of a quadratic equation are
f(x)=(x-r1)(x-r2) where r1 and r2 are the roots
if the roots aka x interctps are -2 and 1/3
f(x)=(x-(-2))(x-1/3)
f(x)=(x+2)(x-1/3)
f(x)=x^2+5/3x-2/3 is the equation
