To the nearest hundredth of a centimeter, what is the length of the hypotenuse?
Answers
Angle formed by hypotenous and one side of triangle = 30°
We can solve this question by using cos30°
So,
In order to find this we use the cosine function and the adjacent side length. Then my cross multiplying and solving, we can get the answer.
.866(HYP) = 32.63
HYP = 37.67

What do percentage means?
- a relative number representing the hundredth part of any quantity One percent (symbolized 1%) is one hundredth part; consequently, 100 percent denotes the complete amount and 200 percent defines twice the supplied amount.
- The most fundamental use of percentages is to compare one number to another, with the second number rebased to 100.
- Percentage simply means "per hundred," and the sign for percentage is%. One percent (or 1%) is one hundredth of a total or whole number and is computed by dividing the whole or entire number by 100.
Total deliveries = 40
completed = 36
percentage of the total deliveries has Lamar completed
= 36/40 * 100 = 90%

Answer:
The percentage of the women have size shoes that are greater than
9.94 is 16%
Step-by-step explanation:
* Lets revise the empirical rule
- The Empirical Rule states that almost all data lies within 3 standard
deviations of the mean for a normal distribution.
- 68% of the data falls within one standard deviation.
- 95% of the data lies within two standard deviations.
- 99.7% of the data lies Within three standard deviations
* The empirical rule shows that
# 68% falls within the first standard deviation (µ ± σ)
# 95% within the first two standard deviations (µ ± 2σ)
# 99.7% within the first three standard deviations (µ ± 3σ).
* Lets solve the problem
- The shoe sizes of American women have a bell-shaped distribution
with a mean of 8.42 and a standard deviation of 1.52
∴ μ = 8.42
- The standard deviation is 1.52
∴ σ = 1.52
- One standard deviation (µ ± σ):
∵ (8.42 - 1.52) = 6.9
∵ (8.42 + 1.52) = 9.94
- Two standard deviations (µ ± 2σ):
∵ (8.42 - 2×1.52) = (8.42 - 3.04) = 5.38
∵ (8.42 + 2×1.52) = (8.42 + 3.04) = 11.46
- Three standard deviations (µ ± 3σ):
∵ (8.42 - 3×1.52) = (8.42 - 4.56) = 3.86
∵ (8.42 + 3×1.52) = (8.42 + 4.56) = 12.98
- We need to find the percent of American women have shoe sizes
that are greater than 9.94
∵ The empirical rule shows that 68% of the distribution lies
within one standard deviation in this case, from 6.9 to 9.94
∵ We need the percentage of greater than 9.94
- That means we need the area under the cure which represents more
than one standard deviation (more than 68%)
∵ The total area of the curve is 100% and the area within one standard
deviation is 68%
∴ The area greater than one standard deviation = (100 - 68)/2 = 16
∴ The percentage of the women have size shoes that are greater
than 9.94 is 16%
Final answer:
Less than 5% of American women have shoe sizes greater than 9.94.
Explanation:
The empirical rule states that for a bell-shaped distribution, approximately 68% of the data falls within one standard deviation of the mean, approximately 95% falls within two standard deviations of the mean, and more than 99% falls within three standard deviations of the mean.
In this case, the mean shoe size for American women is 8.42 and the standard deviation is 1.52. To calculate the percentage of American women with shoe sizes greater than 9.94, we need to find the proportion of the data that falls above this value.
First, we calculate the number of standard deviations that 9.94 is away from the mean: (9.94 - 8.42) / 1.52 = 0.9895 standard deviations.
Based on the empirical rule, we know that approximately 95% of the data falls within two standard deviations of the mean. Since 9.94 is less than two standard deviations away from the mean, we can estimate that less than 5% of American women have shoe sizes greater than 9.94. Therefore, the percentage of American women with shoe sizes greater than 9.94 is less than 5%.
