If angle 5 is 120 degrees, what is the measure of angle 6? Why?

Sliva [168]

Answer:the measure of angle 6 is 60 degrees.

Step-by-step explanation:

The two horizontal lines ate straight and parallel lines. It is established that the sum of the angles on a straight line is 180 degrees. Looking at the given figure, angle 5 and angle 6 are on a straight line. Therefore

Angle 5 + angle 6 = 180 degrees. Therefore,If angle 5 is 120 degrees,then

Angle 6 + 120 = 180

Angle 6 = 180 - 120 = 60 degrees.

Answer:

<h3>The standard error of the mean is <u>15</u></h3>

Step-by-step explanation:

Given that a simple random sample of 64 observations was taken from a large population.

Hence it can be written as n=64

The population standard deviation is 120.

It can be written as $\sigma_{\overline{X}}=120$

The sample mean was determined to be 320.

It can be written as $\overline{X}=\mu =320$

<h3>To find the standard error of the mean :</h3>

The formula for the standard error of the mean is given by

$\sigma_{\overline{X}}=\frac{\sigma}{\sqrt{n}}$

Now substitute the values in the formula we get

$\sigma_{\overline{X}}=\frac{120}{\sqrt{64}}$

$=\frac{120}{8}$

$=15$

$\sigma_{\overline{X}}=15$

<h3>∴ The standard error of the mean is 15</h3>
