find a positive angle less than one revolution around the unit circle that is co-terminal with the given angle -15pi/17

natta225 [31]

ANSWER
$=\frac{19}{17} \pi$

EXPLANATION

To find a positive angle that is coterminal with
$- \frac{15}{17} \pi$

We add multiples of 2π until we get a positive angle that is less than one revolution,

We add to obtain,

$- \frac{15}{17} \pi + 2\pi$

This simplifies to,

$= \frac{19}{17} \pi$

This is the first positive angle that is coterminal with
$- \frac{15}{17} \pi$

and is less than one revolution.

The standard deviation tells us a. the average value of the scores. b. the relative standing of a particular score. c. the skewn

andreyandreev [35.5K]

We can say that the standard deviation tells us <u>the </u><u>dispersion </u><u>of the scores</u>, making <u>option D</u> the correct choice.

<h3>What is the standard deviation?</h3>

A standard deviation (or σ) is a measure of how widely distributed the data is about the mean (μ). A low standard deviation suggests that data is grouped around the mean, whereas a large standard deviation shows that data is more spread out. A standard deviation around 0 suggests that data points are close to the mean, whereas a high or low standard deviation indicates that data points are above or below the mean, respectively.

We use the following formula to compute the standard deviation:

$\sigma = \sqrt\frac{{\sum_{i=1}^{N}\left | x_i - \mu \right | }^2}{N}$

In this formula, σ is the standard deviation, $x_i$ is the data point in the set we are solving for, μ is the mean, and N is the total number of data points.

<h3>How to solve the question?</h3>

In the question, we are asked to tell what standard deviations tell us from the given options.

From the above discussion, we can say that the standard deviation <u>tells us the </u><u>dispersion </u><u>of the scores</u>, making <u>option D</u> the correct choice.
