Answer:
. The waist-to-hip ratio indicates that length of her waist circumference is equal to the 94.9 % of length of her hip circumference.
Step-by-step explanation:
The waist-to-hip ratio of Rachel is:
![n = \frac{37\,in}{39\,in}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B37%5C%2Cin%7D%7B39%5C%2Cin%7D)
![n = \frac{37}{39}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B37%7D%7B39%7D)
![n = 0.949](https://tex.z-dn.net/?f=n%20%3D%200.949)
The waist-to-hip ratio indicates that length of her waist circumference is equal to the 94.9 % of length of her hip circumference.
32= 4x
That would be the equation and x would then be 8
hope this helps
HEY THIS IS NOT A JOKE TAKE IT SERIOUS PLEASE
Answer:
x = 100
Step-by-step explanation:
![57 \degree + (x + 23) \degree = 180 \degree..(straight \: line \: \angle s) \\ (x + 80) \degree = 180 \degree \\ x + 80 = 180 \\ x = 180 - 80 \\ \huge \red{ \boxed{x = 100}}](https://tex.z-dn.net/?f=57%20%5Cdegree%20%2B%20%28x%20%2B%2023%29%20%5Cdegree%20%3D%20180%20%5Cdegree..%28straight%20%5C%3A%20line%20%5C%3A%20%20%5Cangle%20s%29%20%5C%5C%20%28x%20%2B%2080%29%20%5Cdegree%20%3D%20180%20%5Cdegree%20%5C%5C%20x%20%2B%2080%20%3D%20180%20%5C%5C%20x%20%3D%20180%20-%2080%20%5C%5C%20%20%5Chuge%20%5Cred%7B%20%5Cboxed%7Bx%20%3D%20100%7D%7D)
Using the Empirical Rule, the interval that contains 68% of the scores is [81.5, 90.5].
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
68% of the scores are within 1 standard deviation of the mean, hence the bounds of the interval are:
