Let As = smaller pentagon area

(7.5/2.5)^2 = 54/As

As = 6 sq.inches

The answer is 6 in^2

The correct answer is the third option, which is:

 6 inches²

 The explanation is shown below:

 1. You are working with the areas of the pentagons shown in the figure above. Therefore, the ratios are:

 side1²/side2²=A1/A2

 (7.5)²/(2.5)²=54/A2

 Where A2 is the the area of the smaller pentagon.

 2. Therefore, you have that the result is:

 A2=6 inches² (As you can see, it is the third option mentioned above).

the standard deviation of the distribution of sample means (that is, the standard error, σm) is2.94 . (note: although µ and σ ar
pentagon [3]

Using the Central Limit Theorem, the standard error for the distribution of 559 restaurants is given by:

s = 0.0398.

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


The Central Limit Theorem states that for a population with standard deviation \sigma and sample size n, the standard error is given by:

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

For this problem, the parameters are given as follows:

\sigma = 2.94, n = 559

Hence:

s = 2.94/sqrt(559) = 0.0398.

The standard error for the distribution of 559 restaurants is given by:

s = 0.0398.
