Answer:

V = L^3 where v is volume and L the length of one side

A = 6 * L^2 total area of cube with side L

A = 6 * V^2/3 area of cube expressed in V

A2 / A1 = (V2 / V1)^2/3 6 cancels

A2 / A1 = 8^2/3 = 4 ratio of areas

A researcher computes the definitional formula for SS, and finds that Σ(x − M) = 44. If this is a sample of 12 scores, then what

olga_2 [115]

Answer:

Option B.

Step-by-step explanation:

Given information:

Σ(x − M) = 44

where, M is mean.

Sample size = 12

The computational formula for sample variance is

$s^2=\dfrac{\sum (x-M)^2}{N-1}$

where, M is sample mean and N is sample size.

Substitute Σ(x − M) = 44 and N=12 in the above formula.

$s^2=\dfrac{44}{12-1}$

$s^2=\dfrac{44}{11}$

$s^2=4.0$

The sample variance is 4.0.

Therefore, the correct option is B.
