Answers
Answer:
Grade's of most student = 80% (Approx.)
Step-by-step explanation:
Given range:
Range of quiz = 60% to 100%
Find;
Grade's of most student
Computation:
⇒ Grade's of most student = Average grade
⇒ Average mean = Sum of observation / number of observation
⇒ Grade's of most student = [60 + 100] / 2
⇒ Grade's of most student = 160 / 2

Answer:
A. 12.7
Step-by-step explanation:
If line a is parallel to line b, therefore,
(10x - 13.3) = (8x + 12.1) => alternate interior angles theorem
Solve for x
10x - 13.3 = 8x + 12.1
Collect like terms
10x - 8x = 13.3 + 12.1
2x = 25.4
Divide both sides by 2
x = 25.4/2
x = 12.7
Find the Area of the figure below, composed of a rectangle with a semicircle
removed from it. Round to the nearest tenths place.
Answers
Answer:
Area of the figure = 25.7 units²
Step-by-step explanation:
Area of the given figure = Area of rectangle ABCD - Area of the semicircle with diameter CD
Area of the rectangle ABCD = Length × Width
= BC × AB
= 8 × 4
= 32 units²
Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]
Here, r = radius of the semicircle
r = [tex]\frac{\text{Diameter}}{2}[/tex]
r = [tex]\frac{1}{2}(CD)[/tex]
r = [tex]\frac{4}{2}[/tex]
r = 2 units
Therefore, area of the semicircle = [tex]\frac{1}{2}\pi (2)^2[/tex]
= 2π
= 6.28 units²
Area of the given figure = 32 - 6.28
= 25.72 units²
≈ 25.7 units²

a house purchased for 170828 is worth $73828 after 12 years. assuming that the house's value depreciated the same amount from year to year, what was it worth at the end of the year 4? Round to the nearest cent.
Answers
Answer:
After four years the house was worth $128,891.03
Step-by-step explanation:
170828(x)^12 = 73828
solve for x
x = 0.932 (House depreciates by 6.8% yearly)
plug in x and change into function and substitute 4 for 12 because it's 4 years
170828(0.932)^4

A study conducted by a commuter train transportation authority involved surveying a random sample of 200 passengers. The results show that a customer had to wait on the average 9.3 minutes with a standard deviation of 6.2 minutes to buy his or her ticket. Find the upper confidence limit (UCL) for a 95% confidence interval for population mean , the true mean waiting time. Round your answer to two decimal places.
Answers
Answer:
The UCL of the 95% confidence interval for population mean is 10.16 minutes
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 1.96\frac{6.2}{\sqrt{200}} = 0.86[/tex]
The upper end of the interval is the sample mean added to M. So it is 9.3 + 0.86 = 10.16 minutes.
The UCL of the 95% confidence interval for population mean is 10.16 minutes

Please explain your answer instead of just providing the answer for the points!
Answers
Answer:
There are 79,800 ways in which this is possible.
Step-by-step explanation:
The order in which the students are chosen is important(due to different roles), which means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this question:
2 sophomores from a set of 20.
2 freshmen from a set of 15. So
[tex]P_{20,2}*P_{15,2} = \frac{20!}{18!}*\frac{15!}{13!} = 20*19*15*14 = 79800[/tex]
There are 79,800 ways in which this is possible.
