Answer:

x = 50°

Step-by-step explanation:

Angles in a quadrilateral add to 360°

First work out the interior missing angle

360° - ( 40° + 80° + 110° ) = 130°

Angles on a straight line add to 180° so

180° - 130° = 50°

<h3>HELLO</h3>

<u><em>This is neha to help you with</em></u>

<em />

<u>The given figure is a quadrilateral</u>

<h3><u>We know that the sum of angles of a quadrilateral is 360°</u></h3><h3><u>let the missing angle inside the quadrilateral be Y</u></h3>

<em>40°+80°+110°+y= 360</em>

<em>230°+y=360°</em>

<em>y=360°-230°</em>

<em>y=130°</em>

<u>now we have to find the value of x</u>

<em>x+ y= 180° (reason:- angles on a straight line add ups to 180°)</em>

<em>substitute the value of y</em>

<em>x+130°=180°</em>

<em>y= 180°-130°</em>

<em>y= 50°</em>

Pulse rates of women are normally distributed with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per mi
irakobra [83]

Answer:

a) Mean=0 and Standard deviation=1

b) The z-scores have no units of measurement

Step-by-step explanation:

When we convert all the pulse rates of women to z-scores using the formula;

z=\frac{x-\mu}{\sigma} the mean is 0 and the standard deviation is 1.

The reason is that, the resulting distribution of z-scores forms a normal distribution which has a mean of 0 and a standard deviation of 1.

b) The z-scores are standardize scores and has no units of measurement. They give us how many standard deviations below or above the mean of the corresponding values.
