Step-by-step explanation:
When leg one of the triangle is 15ft and leg two is 17 ft you would take 17^2 + 15^2 and then you find the square root of that (514) to get the hypotenuse of the triangle. After that you multiply by two to account for the 2/2 sqaure foot per each unit

A math professor notices that scores from a recent exam are normally distributed with a mean of 61 and a standard deviation of 8. Answer the following questions using integer values.
(a) What score do 25% of the students exam scores fall below?
And, the professor decides to grade on a curve. If he wants .15% of the students to get an A, what is the minimum score required.
I have tried a "calculator" I found online and the answers it provided gave me 50% credit and I don't know which answer is correct as I don't know how to do the actual calculation.
I would appreciate referral to any valid resources as it has been many, many years since I took a math class.
(b) Suppose the professor decides to grade on a curve. If the professor wants 0.15% of the students to get an A, what is the minimum score for an A?
Answer:
a) 25% of the students exam scores fall below 55.6.
b) The minimum score for an A is 84.68.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 61 and a standard deviation of 8.
This means that [tex]\mu = 61, \sigma = 8[/tex]
(a) What score do 25% of the students exam scores fall below?
Below the 25th percentile, which is X when Z has a p-value of 0.25, that is, X when Z = -0.675.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-0.675 = \frac{X - 61}{8}[/tex]
[tex]X - 61 = -0.675*8[/tex]
[tex]X = 55.6[/tex]
25% of the students exam scores fall below 55.6.
(b) Suppose the professor decides to grade on a curve. If the professor wants 0.15% of the students to get an A, what is the minimum score for an A?
This is the 100 - 0.15 = 99.85th percentile, which is X when Z has a p-value of 0.9985. So X when Z = 2.96.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]2.96 = \frac{X - 61}{8}[/tex]
[tex]X - 61 = 2.96*8[/tex]
[tex]X = 84.68[/tex]
The minimum score for an A is 84.68.
the following box plot shows the number of years during which 20 schools have participated in an inter-school swimming meet at least how many schools have participated for 6 years or more?
A: 4
B: 5
C: 10
D: 11
Answer:
4 schools
Step-by-step explanation:
Based on the box plot you have given above, the answer would be 20% of the total schools participated for 6 years or more. This is because the part of the box plot wherein it hits 6 years and above is 20%. Thus, if there are 20 schools, then the 20% of it would be 4. In conclusion, there are 4 schools that participated for 6 years or more.

A researcher surveyed 220 residents of a city about the number of hours they
spend watching news on television each day. The mean of the sample was
1.8 with a standard deviation of 0.35.
The researcher can be 95% confident that the mean number of hours all the
residents of the city are watching news on television is 1.8 with what margin
of error?
Margin of error is 4.645% with 95% confidence that the mean number of hours all the residents of the city are watching news on television is 1.8 .
Data given :
A researcher surveyed 220 residents of a city about the number of hours they spend watching news on television each day. The mean of the sample was 1.8 with a standard deviation of 0.35 .
The researcher can be 95% confident that the mean number of hours all the residents of the city are watching news on television is 1.8 with what margin of error,
By formula of margin of error = [tex]M = 1.96 \times S / \sqrt{N} ,[/tex]
[tex]Margin \ of \ error, \ M = z \times \frac{s}{\sqrt{N}}[/tex]
z - represents the z-value for the required confidence level .
s - represents the standard deviation of the sample .
N - represents the sample size .
Now, using the above information, compute the margin of error as -
[tex]\therefore \ Margin \ of \ error, \ M = z \times \frac{s}{\sqrt{N}} \\= 1.96 \times \frac{0.35}{\sqrt{220}}[/tex]
[tex]=0.04625 (rounded \ to \ 5\ decimal\ places) \\\\ =4.625\%[/tex]
Thus, the margin of error, M, is approximately 4.625% .

Graph the function and its inverse
Given:
The function is:
[tex]f(x)=6x[/tex]
To find:
The inverse of the given function, then draw the graphs of function and its inverse.
Solution:
We have,
[tex]f(x)=6x[/tex]
Step 1: Substitute [tex]f(x)=y[/tex].
[tex]y=6x[/tex]
Step 2: Interchange x and y.
[tex]x=6y[/tex]
Step 3: Isolate variable y.
[tex]\dfrac{x}{6}=y[/tex]
Step 4: Substitute [tex]y=f^{-1}(x)[/tex].
[tex]\dfrac{x}{6}=f^{-1}(x)[/tex]
Therefore, the inverse of the given function is [tex]f^{-1}(x)=\dfrac{x}{6}[/tex] and the graphs of these functions are shown below.

Answer:
4.41
Step-by-step explanation:
The sides of interest in this right triangle are the hypotenuse and the side adjacent to the given angle. The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(25°) = 4/AB
Multiplying by AB and dividing by cos(25°), we get ...
AB = 4/cos(25°)

Ronald runs 6,000 meters in 2 hours. He is thinking of running an 18 kilometers race. How much time will he take in the race if he maintains the same speed?
Answer:
6 hours
Step-by-step explanation:
speed = distance/ time
6000meters to km = 6000/1000= 6km
speed for the first race = 6/2
speed = 3km/hr
for the second race
speed = distance/time
3 = 18/time
cross multiply
3* t = 18
divide both sides by 3
t = 18/3
t = 6 hours
Answer:
Ronald will take 6 hours to complete the 18 km race if he maintains this speed.
Step-by-step explanation:
6000m in 2h = 6km in 2h
multiply by 3:
18km in 6h
