A person who invests $3,500 in a bank paying 6.75% interest compounded quarterly, must leave it for a period of 53 quarters (13 years) to reach a future value of $8,500.
What is the future value?The future value is the product of the compounded present value at an interest rate for some periods.
Compounding involves charging interest on the accumulated interest and principal, unlike the simple interest system.
When we are given the interest rate, and present and future values, we can determine the period from an online finance calculator as follows:
I/Y (Interest per year) = 6.75%
PV (Present Value) = $3,500
PMT (Periodic Payment) = $0
FV (Future Value) = $8,500
Results:
N (# of periods) = 53.023
Total Interest = $5,000.00
Thus, the investor needs 53 quarters (13 years) to accumulate a future value of $8,500.

a manufacturer is interested to develop a 95% confidence interval for the true mean cycle time of producing their headphones. assuming a margin of error of 1 minute, and standard deviation of 6 minutes from a previous sample, what is the appropriate sample size?
The appropriate sample size for the 95% confidence interval is given as follows:
139.
How to obtain the appropriate sample size?To obtain the appropriate sample size for the confidence interval, we need to look at it's equation for the margin of error, which is defined as follows:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which the parameters are listed as follows:
z is the critical value.n is the sample size.[tex]\sigma[/tex] is the standard deviation for the population.The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
The margin of error and the population standard deviation have the values given as follows:
[tex]M = 1, \sigma = 6[/tex]
Then the sample size is obtained as follows:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]1 = 1.96\frac{6}{\sqrt{n}}[/tex]
[tex]\sqrt{n} = 1.96 \times 6[/tex]
[tex](\sqrt{n})^2 = (1.96 \times 6)^2[/tex]
n = 139 (rounded up, as for a sample size of 138 the margin of error would be slightly above 1).

In a recent survey, the proportion of adults who indicated mystery as their favorite type of book was 0.325. Two simulations will be conducted for the sampling distribution of a sample proportion from a population with a true proportion of 0.325. Simulation A will consist of 1,500 trials with a sample size of 100. Simulation B will consist of 2,000 trials with a sample size of 50. Which of the following describes the center and variability of simulation A and simulation B?
Option c) The centers will roughly be equal, and the variability of simulation A will be less than the variability of simulation B
According to the information given in the question,
A true proportion of 0.325 represents that the two simulations will be conducted for sampling proportions from a population
Simulation A -
Sample size - 100
Trials - 1500
Simulation B -
Sample size - 50
Trials - 2000
Now due to the relation of simulation A and simulation B, they are closely equal-
The total sample size of simulation A= 1500 x 100
= 150000
The total sample size of simulation B = 2000 x 50
= 100000
From the above calculations of simulations A and B, we can see that while comparing the,
Sample Size = Simulation A > Simulation B
Variability = Simulation B < Simulation B
Therefore, option c) The centers will roughly be equal, and the variability of simulation A will be less than the variability of simulation B is correct.

What is the principle of conservation of energy?
The word "conservation" in physics describes anything that doesn't change. This indicates that a conserved quantity is represented by a variable in an equation that is constant over time. Its value is the same whether an event occurs before or after it.
In physics, there are a lot of conserved quantities. For making forecasts in what would otherwise be exceedingly complex situations, they are frequently remarkably useful. There are three fundamental quantities in mechanics that are conserved. They are power, forward motion, and angular momentum.
According to question
Mass of the ball = 0.2 kg
Maximum height of the ball = 4 m
Gravity = 9.8 m/s²
Therefore:
Using conservation of energy, we know that P.E. top = K.E. bottom. This tells us that the potential energy at the top is all converted to kinetic energy at the bottom. We can substitute the equations for potential energy and kinetic energy
Initial kinetic energy + Initial potential energy = Final kinetic energy + Final potential energy
1/2mv² + 0 = mgh + 0
½(0.2)v² = (0.2)(9.8)4
v² = 78.4

You are working on an air conditioning system. A roll of cylindrical copper tubing has an outside diameter of 78 7 8 inch and an inside diameter of 34 3 4 inch. How much refrigerant can 12 feet of the tubing hold?.
557,568 inch³ of refrigerant can be held by the tubing.
Here we have to find how much a refrigerant can hold.
Data given:
outer diameter (d) = 78inch
outer radius(r) = 39 inch
inner diameter (d') = 34 inch
inner radius (r') = 17inch
Height (h) = 12 feet
= 12 × 12
= 144 inch
the formula to find the volume of the cylinder:
volume= пr²h
So here we get
Refrigerant hold = Volume of the outer cylinder - the volume of the inner cylinder
= πr²h - πr'²h
= πh(r² - r'²)
= π ×144 ( 39² - 17²)
= π × 144 ×56 × 22
= 22/7 × 144 × 56 × 22
= 557,568 inch³

What is the slope of the line that passes through 4 1 and 2 5?
The slope of the line that passes through (4,1) and (2,5) is -2.The slope of a line can be expressed in many ways, including as a fraction, decimal, or even in terms of the angle of inclination.
The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.The slope of a line is calculated by finding the difference in the y-values (rise) divided by the difference in the x-values (run).
In this case, the rise is 5 - 1 = 4 and the run is 2 - 4 = -2.
Therefore, the slope of the line is 4/-2 = -2.
In the case of a horizontal line, the slope is 0, and in the case of a vertical line, the slope is undefined. The slope is a useful tool in mathematics as it can be used to determine the equation of a line, the rate of change on a graph, or the amount of change for every unit of time. It can also be used to determine the area between two points on a graph. Slope is an essential concept in mathematics and can be used to solve many types of problems.

What is a dilation?
Dilation is a process of changing a thing. It is a process of transformation that to make the objects smaller or larger, with the use of specific scale factor.
The new figure that is the result of dilation is known as the image. Initial figure is referred to as the pre-image.
What is a center of dilation?
Center of dilation is the resizing that happens from a point. The objects/figures are expanded or contracted from the center of dilation.
Scale factor is a figure by which the size of any geometrical figure can be resized, with respect to its original size. The scale factor is multiplied to get image.

28 divided 66.29 please
Answer:
28 divided by 66.29 is approximately 0.4223. To find the exact result, you would need to perform long division. The process for doing this is as follows:
Begin by dividing the leftmost digit of the dividend (28 in this case) by the divisor (66.29). In this case, the result is 0 with a remainder of 28.
Bring down the next digit of the dividend (0 in this case), so that the dividend is now 280.
Divide 280 by 66.29. The result is 4 with a remainder of 36.29.
Bring down the next digit of the dividend (0 in this case), so that the dividend is now 36.29.
Divide 36.29 by 66.29. The result is 0.54 with a remainder of 0.29.
Bring down the next digit of the dividend (0 in this case), so that the dividend is now 0.29.
Divide 0.29 by 66.29. The result is 0.004 with a remainder of 0.
The remainder is 0, so the division is complete. The result is 0.004223.
Alternatively, you can use a calculator to perform the division. Just enter "28 / 66.29" and the calculator will give you the result.

Which absolute value functions will be narrower than the parent function, f(x) = |x|? check all that apply.
The absolute value function which will be narrower than the parent function is:
f(x) = 2.9|x|
Given parent function is f(x)=|x|
Now we have to find which function from given choices will be narrower than the parent function.
Notice that adding or subtracting some number from the parenth function only shifts the graph up, down, left of right side.
But that will not make function narrorwer or broader.
So f(x) = |x – 2| and f(x) = |x| + 3, can't be the answer.
Multiplying by some positive real number which is more than 1, makes function narrower.
Only f(x) = 2.9|x| from remaining choices fits that case.
Hence f(x) = 2.9|x| is the final answer.
f(x) = 1.2|x + 8| will also make the function narrower but will shift the parent function too.
