Determine the value of angle x and angle y

ss7ja [257]

Answer:

80

Step-by-step explanation:

Sum of interior angles of a polygon = (n-1)x180= (6-2)x180=720

Since this looks like a regular hexagon each interior angle =720/6=120

Hence the inside angle touching the line is 120 (inside the hexagon)

Since one side of the hexagon is parallel to the line, y and 20 form adjacent angle, sum 180,

Then y= 180-20=160

Then x=360-(160+120)=80 because sum of all angles round a point=360

The army reports that the distribution of waist sizes among female soldiers is approximately normal, with a mean of 28.4 inches

____ [38]

Using the normal distribution, it is found that:

a) Her waist is at the 2.74th percentile.

b) 99.86% of female soldiers requires custom uniform pants.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation are given, respectively, by:

$\mu = 28.4, \sigma = 1.2$ .

Item a:

The percentile is the <u>p-value of Z when X = 26.1,</u> hence:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{26.1 - 28.4}{1.2}$

Z = -1.92

Z = -1.92 has a p-value 0.0274 = 2.74th percentile.

Item b:

The proportion is the <u>p-value of Z when X = 32 subtracted by the p-value of Z when X = 24</u>, hence:

X = 32:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{32 - 28.4}{1.2}$

Z = 3.

Z = 3 has a p-value 0.9987.

X = 24:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{24 - 28.4}{1.2}$

Z = -3.67.

Z = -3.67 has a p-value 0.0001.

0.9987 - 0.0001 = 0.9986 = 99.86% of female soldiers requires custom uniform pants.

A cereal company is creating new boxes for its product. In order to display the boxes, the stores they sell to require that the

SashulF [63]

If the problem says "space", that usually means that they are talking about volume. The maximum length the box can be is 8.4 inches. To find volume, you do length * width * height. You know the length and height, as well as the volume. You can replace the width with "x". Your equation should be:

11.5 * 8.4 * x = 272.8

Then you can just solve for x by dividing both sides by (11.5 * 8.4). The answer should be about 2.82 inches.
