Using addition of variables, it is found that the mean of S is of 73 and the standard deviation is of 8.5.

<h3>What happens to the mean and the standard deviation when two variables are added?</h3>

The mean is the sum of the means.

The standard deviation is the square root of the sum of variances.

In this problem, for variables A and B, we have that:

$\mu_A = 35.5, \sigma_A = 5.1$

$\mu_B = 37.3, \sigma_B = 6.8$

Variable S is the sum of A and B, hence:

$\mu_S = \mu_A + \mu_B = 35.5 + 37.3 = 73$

$\sigma_S = \sqrt{\sigma_A^2 + \sigma_B^2} = \sqrt{5.1^2 + 6.8^2} = 8.5$

The mean of S is of 73 and the standard deviation is of 8.5.

Select the simplification that accurately explains the following statement.<br> (from clever)

gavmur [86]

Answer:

OPTION C

Step-by-step explanation:

We know that $(\textbf{x}^{\textbf{a}} )^{\textbf{b}} \hspace{5mm} \textbf{=} \hspace{5mm} \textbf{x}^{\textbf{a . b}}$

Also, $\textbf{x}^{\textbf{a}}. \textbf{x}^{\textbf{a}} \textbf{=} \textbf{x}^{\textbf{a + a}} \textbf{=} \textbf{x}^{\textbf{2a}}$

Using the above two results, we can say that:

$\sqrt{9} = 9^{\frac{1}{2}}$

$\bigg ( 9^{\frac{1}{2}} \bigg )^2 = 9^{\frac{1}{2}}. 9^{\frac{1}{2}}$

$= 9^{\frac{1}{2} + \frac{1}{2}}$ (Using (ii) result)

$= 9^{1} = \textbf{9}$

Hence, OPTION C is the correct answer.
