Answer:

$m\angle WZY = 24^\circ$

Step-by-step explanation:

<u>Angles and Lines</u>

The figure shows two triangles WXZ and WYZ. Considering:

* Angles WXZ and WYZ are right (90°)

* Sides XW and YW are congruent (red marker on both)

* They share the side WZ.

We can conclude they are congruent. Thus, angles XZW and YZW are congruent or have the same measure:

5x + 4 = 6x

Subtracting 5x:

4 = x

Or, x =4

Thus:

$m\angle WZY = 6x = 24^\circ$

$\mathbf{m\angle WZY = 24^\circ}$

Answer:

Option D) The number of standard deviations a measurement is from the mean

Step-by-step explanation:

Standard Score:

Standard score is also known as the z-score, z-value, normal scores or the standardized score.
It tells us about the values of standard deviations by which the value of data point is above or below the mean value.
The standard score for a data point may be negative or positive.
It is obtained by subtracting the population mean from the data point and then dividing it by the population standard deviation.
$z = \displaystyle\frac{x-\mu}{\sigma}$
It is known as standardization or normalization.
