The values that exist two standard deviations above and below the mean are 681 and 265.

<h3>How to determine the values?</h3>

The given parameters exist:

Mean = 473

Standard deviation =104

The values above and below the mean exist calculated utilizing:

$x=\bar{x} \pm n \sigma$

In this case n = 2.

So, we have, $x=\bar{x} \pm 2 \sigma$

The value above is:

x = 473 + 2 $*$ 104 = 681

The value below is:

x = 473 - 2 $*$ 104 = 265

Therefore, the values that exist two standard deviations above and below the mean are 681 and 265.

To learn more about standard deviation refer to:

Find the midpoint of CH if C has coordinates (-5,-2) and H has coordinates (9,-4)

Sati [7]

Answer:

(2,1)

Step-by-step explanation:

$\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\\\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)\\\\\left(x_1,\:y_1\right)=\left(-5,\:-2\right),\:\left(x_2,\:y_2\right)=\left(9,\:4\right)\\\\=\left(\frac{9-5}{2},\:\frac{4-2}{2}\right)\\\\= (\frac{4}{2} , \frac{2}{2} )\\\\=\left(2,\:1\right)$

How can you check to see if two ratios form a proportion? Explain the method you used to find the answer to the previous problem

antiseptic1488 [7]

Answer:

In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
