t is known that the population variance equals 484. With a 0.95 probability, the sample size that needs to be taken if the desired margin of error is 5 or less is 25 74 189 75 None of the above answers is correct
Answer:
The sample size needed to be taken is approximately 74.
Step-by-step explanation:
To get alpha; we have 1 - 0.95 = 0.05
Therefore, [tex]z_{\frac{a}{2} } = \frac{0.05}{2} = 0.025[/tex]
The we look up z* in a Standard Normal table where α = 0.025 area in each tail.
From the table, z* = 1.96
From the question variance is 484, then the standard deviation is 22
Standard deviation = [tex]\sqrt{Var(x)} = \sqrt{484} = 22[/tex]
And margin of error is 5 or less
The formula for margin of error is given as:
margin of error = [tex]\frac{(z^{*}) (SD)}{\sqrt{n} }[/tex]
[tex]5 = \frac{1.96 * 22}{\sqrt{n} } \\5 = \frac{43.12}{\sqrt{n} } \\5 * \sqrt{n} = 43.12\\(5)^{2} * (\sqrt{n} )^{2} = (43.12)^2\\25 * n = 1859.3344\\25n = 1859.3344\\\frac{25n}{25} = \frac{1859.3344}{25} \\n = 74.373376\\n = 74[/tex]

A company is designing a new cylindrical water
bottle. The volume of the bottle will be 162 cm3.
The height of the water bottle is 7.7 cm. What is
the radius of the water bottle? Use 3.14 for It.
Answer:
21
Step-by-step explanation:
To find the area of a cylinder you mutliply radius by height.
r*h = 162
If we know the height is 7.7, substitute it for h.
r*7.7 = 162.
Or:
162 / 7.7
Which gives you 21.03, or 21.
2- En una habitación cuadrada de 4 m de lado se coloca una alfombra circular de 3 m de diámetro. ¿Cuál es la superficie cubierta por la alfombra? ¿Cuál es la superficie del cuarto no cubierto por la alfombra
Answer:
7.065 m ^ 2
8.935 m ^ 2
Step-by-step explanation:
The first thing is to calculate the surface of each one, that is, the area
For the room that is square, each side measures 4m, therefore:
As = 4 * 4 = 16 m ^ 2
The area of the carpet is that of a circle, that its area is the number pi times the radius squared, we know that the radius is half the diameter, therefore r = 3/2 = 1.5 m
replacing in the area formula
Ac = pi * r ^ 2 = 3.14 * 1.5 ^ 2
Ac = 7.065 m ^ 2
In other words, the area covered by the carpet is 7,065 m ^ 2 and the area not covered would be the subtraction between the area of the room minus the area of the carpet, that is:
16 m ^ 2 - 7.065 m ^ 2 = 8.935 m ^ 2
8.935 m ^ 2 would be the area that the carpet does not subside.
A beam of light is transmitted through a medium with an index of refraction of 1.46. What is the speed of the light beam as it travels through the medium?
Answer:
The speed of light through the medium is 2.1 * 10^8 m/s
Step-by-step explanation:
In this question, we are asked to calculate the speed of light beam as it travels through a medium given the refractive index of the medium.
Mathematically;
n = c/v
where n is the refractive index, v is the speed of light through the medium and c is the speed of light in a vacuum.
From the question, we can identify that the refractive index is 1.46 and the speed of light through vacuum is 3 * 10^8 m/s
Rearranging the equation; we have;
v = c/n
v = (3 * 10^8)/1.46
v = 2.1 * 10^8 m/s
There are 135 people in a sport centre. 73 people use the gym. 59 people use the swimming pool. 31 people use the track. 19 people use the gym and the pool. 9 people use the pool and the track. 16 people use the gym and the track. 4 people use all three facilities. Given that a randomly selected person uses the gym and the track, what is the probability they do not use the swimming pool?
The probability that a person who uses the gym and the track does not use the swimming pool is 3/4.
Explanation:We are asked to find the probability that a person who uses the gym and the track does not use the swimming pool. The number of people who use both the gym and the track is 16. Among these, 4 also use the pool, which means that 16 - 4 = 12 people use just the gym and the track, and not the pool. The probability that a randomly selected person who uses the gym and the track does not use the pool is calculated as the number of gym-and-track users who don't use the pool divided by the total number of gym-and-track users, which is 12/16 or 3/4.

what is the slope of a line perpendicular to the line whose equations is x-y=-3?
The slope of a line perpendicular to the line with equation x - y = -3 is -1, as perpendicular lines have slopes that are negative reciprocals of each other.
The slope of the line perpendicular to the line whose equation is x - y = -3 can be found by first writing the equation in the slope-intercept form (y = mx + b) to determine the slope of the given line. By rearranging the given equation to y = x + 3, we can see that the slope (m) of the line is 1. Since perpendicular lines have slopes that are negative reciprocals of each other, the slope of a line perpendicular to this one would be the negative reciprocal of 1, which is -1. Therefore, the slope of the line perpendicular to the line with equation x - y = -3 is -1.
Students in a college statistics class want to conduct a survey to determine the percentage of students in the school who are willing to pay a fee for participating in extracurricular activities. thirty students are randomly selected to complete the survey from each of the freshman, sophomore, junior, and senior classes. this plan is an example of which type of sampling?
a. convenience sampling
b stratified sampling
c. simple random sampling
d.a cluster sampling
b. stratified sampling
The plan to determine the percentage of students in a school willing to pay a fee for participating in extracurricular activities is an example of stratified sampling. In stratified sampling, the population is divided into subgroups or 'strata' that share similar characteristics, and a random sample is taken from each stratum. In this case, the classes (freshman, sophomore, junior, and senior) serve as the strata, and thirty students from each class are randomly selected to complete the survey. This approach ensures that each subgroup is adequately represented in the sample, making the results more reflective of the entire school population.
To determine how a city's residents feel about building a new youth center, a group considers surveying 50 random children at a local elementary school. Why would this result in a biased sample? Select three answers.
Answer:
This would most probably result in biased sample since only a specific part of the community is being surveyed that does not represent all of the community.
Step-by-step explanation:
A survey is being conducted to determine how a city's residents feel about building a new youth center.
They are considering to survey 50 random children at a local elementary school.
This would most probably result in biased sample since only a specific part of the community is being surveyed that does not represent all of the community.
Moreover, it is likely that the students of elementary school might not even have any interest in youth center so results would be biased.
Therefore, it is suggested to include a variety of samples that is surveying different age groups that covers all of the community.
Answer:
1. The survey is only considering elementary school students, but not children in middle school or high school.
2. The survey is also not considering any adult at all. Most likely they represent the majority of the local residents.
3. Finally, it's important to understand in advance what would be the main differences with the current youth center and include those specific questions in the survey. It's important to determine if the new youth center will fill the gap.

Hermosa Menendez is employed by Chemical Industries. She has a family membership in the group preferred provider organization (PPO). The annual premium is $6,180. Her employer pays 75 percent of the premium.
a) How much does the employer pay annually
b) How much does she pay annually
c) How much is deducted each week as her weekly cost
a)
Given that:
The annual premium = $6180
Employers percent = 75% = 0.75
The money the employer pays annually = Annual premium × Employers percent = $6180 × 0.75 = $4635
b)
Since the employers percent = 0.75, her percent = 1 - 0.75 = 0.25
The money that she would pay annually = Annual premium × her percent = $6180 × 0.25 = $1545

Sue bought 54 ft of lumber for building a window frame each window frame requires 13 1/2 feet of lumber how many window frames how many window frames can she make
Answer:
The correct answer is 4 window frames.
Step-by-step explanation:
Sue bought 54 feet of lumber for building window frame.
Each window frame requires 13 1/2 feet = [tex]\frac{27}{2}[/tex] feet of lumber.
Therefore the number of window frames Sue can make with 54 feet of lumbers she bought is given by dividing the total amount of lumber she has by the lumber it takes to make a single window frame.
= [tex]\frac{54}{27}[/tex] × 2 = 2 × 2 = 4
Thus Sue can make 4 window pane from 54 feet of lumber, each of 13 and a half feet.
Sue can make 4 window frames with the 54 feet of lumber she purchased, as each frame requires 13.5 feet.
Sue bought 54 feet of lumber to build window frames, with each window frame requiring 13.5 feet of lumber. To determine how many window frames Sue can make, we divide the total amount of lumber by the amount required for one frame.
Here's the calculation:
Start with the total amount of lumber: 54 feet.
Divide this by the amount required for one window frame: 13.5 feet.
Perform the division: 54 / 13.5 = 4.
Sue can make 4 window frames with the lumber she has purchased.

The number of yards of fabric needed for Robs costume is (7/8+1/2+1 3/4)÷2. How does the amount of fabric needed for Robs costume compare to the amount needed for jimmys costume ?Explain
The amount of fabric needed for Jimmy's costume is not stated, we can only determine the amount needed for Rob's costume, which makes it impossible to compare the amounts needed for both of their costumes. If this omission was an error, then you can find the difference between these amounts if the amount needed for Jimmy's costume is stated explicitly.
Step-by-step explanation:
The number of yards of fabric needed for Robs costume is (7/8+1/2+1 3/4)÷2
Assuming 1 3/4 is a mixed fraction.
= (7/8 + 1/2 + 7/4) ÷ 2
= (7 + 4 + 2) ÷ (8 × 2)
= 13/16 yards
Suppose 2 yards of fabric is needed for Jimmy's costume, then comparing with Rob's yards, we see that Jimmy's costume requires (2 - 13/16 = 19/16) more yards than Rob's costume.
