Here are the prices for 8 different MP3 players. Find the standard deviation.
Elis [28]
The mean is 250.875.

Using this information, I can put the following into a calculator:
√(((250.875-195)²+(250.875-358)²+(250.875-201)²+(250.875-276)²+
(250.875-161)²+(250.875-301)²+(250.875-387)²+(250.875-128)²)÷8)

Which equals:
87.9878

This is the standard deviation of the MP3 players.

RST has vertices R(0,0), S(10,5), and T(5,-5). R’S’T’ is the image of RST after a dilation with center (0,0) and scale factor 1/
AysviL [449]

The coordinates of the point S' is (2,1)

Explanation:

Given that the RST has vertices R(0,0), S(10,5) and T(5,-5)

The image R'S'T' is the image of RST after a dilation with center (0,0) and scale factor \frac{1}{5}

We need to determine the coordinates of the point S'

The coordinates of S' can be determined by multiplying both the x and y - coordinates of the point S with the scale factor \frac{1}{5}

Let us consider the x - coordinate of the point S and multiply it with the scale factor \frac{1}{5}

Thus, we have,

x - coordinate of the point S' is given by

10 \times \frac{1}{5}=2

Thus, the x - coordinate of the point S' is 2

Similarly, the y - coordinate of the point S' can be determined by multiplying the point S with the scale factor \frac{1}{5}

Thus, we have,

The y - coordinate of the point S' is given by

5\times\frac{1}{5}=1

Thus, the y - coordinate of the point S' is 1

Hence, the coordinates of the point S' is (2,1)
