Answer:
Step-by-step explanation:
=> Since it is an equilateral (Having all angles and all sides equal) triangle, so every angles will be equal to the other.
=> The sum of the measures of interior angles of triangle add up to 180 degrees.
So,
3x + 3x + 3x = 180
9x = 180
Divide both sides by 9
x = 20

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 and standard deviation
is given by:
- 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:
.
Item a:
The percentile is the <u>p-value of Z when X = 26.1,</u> hence:
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 = 3.
Z = 3 has a p-value 0.9987.
X = 24:
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.
