A sample of n=8 scores has a mean of m=12. What is the value of ∑x for this sample
Andrews [41]

A sample of n=8 scores has a mean of m=12. What is the value of ∑x for this sample

Answer: We are given the mean of 8 scores is 12.

We are required to find the sum of these 8 observation's, \sum x

We know that:

\bar{x}=\frac{\sum x}{n}

We are given:

\bar{x} = 12, n=8

\therefore 12=\frac{\sum x}{8}

      \sum x = 12 \times 8

      \sum x=96

Hence, sum of 8 observation's, \sum x =96

The area of a regular hexagon is 14.96 cm2. What is the perimeter of the hexagon? A. 1.2 space c m B. 1.2 square root of 3 space
victus00 [196]

Answer:

14.4 cm

Step-by-step explanation:

The formula for the area of a regular hexagon in terms of its side length s is ...

... A = (3√3)/2·s²

Then the side length is ...

... s = √(2A/(3√3))

and the perimeter is ...

... P = 6s = √(8A√3)

For your area, this is ...

... P = √(8·14.96·√3) ≈ √207.292 ≈ 14.4 . . . . cm
