Using the Central Limit Theorem, the standard deviation of the sampling distribution of sample means would be of 0.86.

<h3>What does the Central Limit Theorem state?</h3>

It states that the standard deviation of the sampling distribution of sample means is given by:

$s = \frac{\sigma}{\sqrt{n}}$

In which:

$\sigma$ is the standard deviation of the population.

n is the sample size.

The parameters for this problem are given as follows:

$\sigma = 6.8, n = 63$ .

Hence:

$s = \frac{\sigma}{\sqrt{n}}$

$s = \frac{6.8}{\sqrt{63}}$

s = 0.86.

How do I find the value of x

Kaylis [27]

Answer:

The angles inside a hexagon add up to 720.

105 + 88 + 142 + 140 + 124 + x = 720

720 - (105 + 88 + 142 + 140 + 124) = x

720 - 599 = x

Figure out this number pattern:<br>1,5,14,30,55

Amanda [17]

5 - 1 = 4 = 2^2

14 - 5 = 9 = 3^2

30 - 14 = 16 = 4^2

55 - 30 = 25 = 5^2

Start with 1, then add 2^2, 3^3, 4^2, 5^2, 6^2, etc.
