Answers

Answer 1

Answer: The answer is state B because there is less variability in larger populations so estimates from samples are more accurate. The standard error of the mean is proportional to the standard deviation of the population and inversely proportional to the square root of the sample size. Since state B has a much larger population, it is more likely that our sample mean will be within $80 of $2,600 for state B than for state A.

Writing What is the volume of the sphere? Use 3.14 for . Use pencil and paper. Describe how the volume of the sphere changes if the radius is increased by 1. radius is 19 in​

Answers

Comparing the two volumes, we can see that the volume of the sphere decreased when the radius was increased by 1 inch. This is because the volume of a sphere increases with the cube of its radius, so small changes in the radius can result in significant changes in the volume.

What is volume?

A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder, or a sphere. Different shapes have different volumes.

To find the volume of a sphere, we use the formula:

V = (4/3)πr³

where "r" is the radius of the sphere and "π" is approximately 3.14.

If the radius of the sphere is 19 inches, we can substitute this value into the formula to find its volume:

V = (4/3)π(19)³

V = (4/3)π(6859)

V = 36,236.71 cubic inches (rounded to two decimal places)

Therefore, the volume of the sphere with a radius of 19 inches is approximately 36,236.71 cubic inches.

If the radius is increased by 1 inch to 20 inches, we can find the new volume of the sphere using the same formula:

V = (4/3)π(20)³

V = (4/3)π(8000)

V = 33,510.32 cubic inches (rounded to two decimal places)

Hence, Comparing the two volumes, we can see that the volume of the sphere decreased when the radius was increased by 1 inch. This is because the volume of a sphere increases with the cube of its radius, so small changes in the radius can result in significant changes in the volume.

Three-fourths of a number less than 6 is 10 formula

Answers

The unknown number in the statement is 64/3.

Calculating the value of the number

The problem can be translated into an algebraic equation as follows:

(3/4)x - 6 = 10

where x is the unknown number we are trying to find.

To solve for x, we need to isolate it on one side of the equation. We can start by adding 6 to both sides:

(3/4)x = 16

Next, we can multiply both sides by the reciprocal of 3/4, which is 4/3:

x = (4/3) * 16

x = 64/3

Therefore, the solution to the equation is x = 64/3, which means that the unknown number is 64/3.

Carrie will have $15,481.24 after taxes for a year assuming she works 52 weeks.

First, let's calculate the total taxes she pays each week:

Federal income tax rate = 10% of $350.15 = $35.02

State income tax rate = 5% of $350.15 = $17.51

Total taxes per week = $35.02 + $17.51 = $52.53

Now, we can calculate the total amount of taxes she pays for a year:

Total taxes for a year = $52.53 x 52 weeks = $2,731.56

Amount Carrie will have after taxes for a year:

Annual income before taxes = $350.15 x 52 weeks = $18,212.80

Net income after taxes = Annual income before taxes - Total taxes for a year

Answers

The solution to the system equation after it is solved, would be x = 3 and y = 7.

How to solve the system equation ?

To solve the given system of linear equations:

8x - 3y = 3

3x - 2y = -5

We can use the method of substitution or elimination. In this case, I will use the elimination method.

First equation x 2:

16x - 6y = 6

Second equation x 3:

9x - 6y = -15

Now, subtract the second equation from the first equation to eliminate the y variable:

(16x - 6y) - (9x - 6y) = 6 - (-15)

16x - 9x = 21

7x = 21

x = 21 / 7

x = 3

Next, substitute the value of x back into either of the original equations to find the value of y.

8x - 3y = 3

8(3) - 3y = 3

24 - 3y = 3

-3y = -21

In 2010, the population of a city was 89,000. From 2010 to 2015, the population grew by 6.8%. From 2015 to 2020, it fell by 4.9%. To the nearest whole number, by what percent did the city grow from 2010 to 2020?

Answers

1.35% is the percentage change in the population of the city that grew from the years 2010 to 2020.

The population of the city = 89,000

Percentage in the growth of people from 2010 to 2015 = 6.8%

Percentage in the decline of people from  2015 to 2020 = 4.9%

The formula to calculate the percentage change is:

percentage change = (new value - old value) / old value x 100%

To calculate the population of the city after the growth of 6.8%

Population in 2015 = 89,000 x (1 + 6.8/100)

Population in 2015 = 95,012

To calculate the population of the city after the decline of 4.9%

Population in 2020 = 95,012 x (1 - 4.9/100)

Population in 2020 = 90,199.88

Population in 2020 = 90,200

The total change in the percentage of growth of population in the city is:

percentage change = (new population - old population) / old value * 100%

percentage change = (90,200 - 89,000) / 89,000 x 100%

percentage change = 1,200 / 89,000 x 100%

percentage change = 1.35%

Therefore, we can conclude that the population in the city grew by 1.35% from 2010 to 2020.

Trend component is easy to identify by using
A. Moving average
B. Exponential smoothing
C. Regression analysis
D. Delphi approach

Answers

Trend component is easy to identify by using Moving average, Exponential smoothing, Regression analysis. So, correct options are A, B and C.

The trend component of a time series is a long-term movement in the data that represents a gradual increase or decrease over time. It is an important component of time series analysis because it can provide insights into the overall direction of the data and help forecast future trends.

One of the easiest ways to identify the trend component of a time series is by using a moving average. A moving average is a statistical method that calculates the average of a set of data over a specified period of time. By calculating the moving average, we can smooth out the short-term fluctuations in the data and identify the underlying trend.

Exponential smoothing is another method that can be used to identify the trend component of a time series. It is a forecasting technique that assigns exponentially decreasing weights to older observations, which places greater emphasis on more recent data.

This approach can help identify the trend by smoothing out the data and highlighting the underlying pattern.

Regression analysis can also be used to identify the trend component of a time series. It involves fitting a mathematical model to the data and identifying the relationship between the independent and dependent variables.

If the independent variable represents time and the dependent variable represents the data being analyzed, then regression analysis can help identify the trend component.

The Delphi approach is not typically used to identify the trend component of a time series. It is a forecasting technique that involves gathering expert opinions and using them to make predictions about future events.

In conclusion, the methods that are most commonly used to identify the trend component of a time series are moving average and exponential smoothing. Regression analysis can also be used in certain situations.

In the context of relationships, the term "weight" refers to the importance or influence of a particular relationship. Not all relationships have equal weight because the significance of each relationship varies based on factors such as trust, communication, shared experiences, and emotional connections.


Some relationships are naturally stronger and more influential than others due to these factors, making them more valuable and impactful in a person's life. In contrast, weaker relationships may not have the same level of trust, connection, or influence, making them less important overall.

Two numbers have a difference of -72 and a product of -720? What is their sum?

Answers

The answer to the question "difference of -72 and a product of -720?" is -9.

What is the sum of two numbers with a difference of -72 and a product of -720?

To find the sum of the two numbers, we can set up the following equations based on the given information:

Let the two numbers be x and y, where x > y.

x - y = -72 (since the difference between the numbers is -72)

xy = -720 (since the product of the numbers is -720)

We can solve these equations simultaneously using algebraic methods. One way to do this is to isolate one of the variables in one of the equations and substitute it into the other equation. For example, we can isolate y in the first equation by rearranging it to y = x + 72, and then substitute this into the second equation:

x(x + 72) = -720

Expanding the left-hand side, we get:

x^2 + 72x = -720

Rearranging the equation, we get:

x^2 + 72x + 720 = 0

Now we can solve for x using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

where a = 1, b = 72, and c = 720. Plugging in these values, we get:

x = (-72 ± √(72^2 - 4(1)(720))) / (2(1))

Simplifying further, we get:

x = (-72 ± √(5184 - 2880)) / 2

x = (-72 ± √2304) / 2

x = (-72 ± 48) / 2

Now we have two possible values for x:

x1 = (-72 + 48) / 2 = -12

x2 = (-72 - 48) / 2 = -60

Since x > y, we take x = -12 and y = -72 - (-12) = -60 + 12 = -48.

Thus, the sum of the two numbers is -9, which is obtained by adding x and y:

-12 + (-48) = -9.

The amount that an employer withholds from an employee's paycheck to pay for taxes, insurance premiums, and other deductions like retirement contributions or wage garnishments is known as a withholding. Before the employee receives their net pay—the amount they actually take home after all deductions are done—these deductions are made.

For Miguel, taxes, insurance, and retirement plan payments total $783, and these are taken from each pay period. His net pay would be the amount he receives after this $783 has been subtracted from his gross income. This $783 reflects his withholdings.

How to find the vertex of the parabola?

To find the quantity of things that will augment the benefit, we want to find the vertex of the parabola addressed by the given capability.

The vertex of a parabola in the form of[tex]y = ax^2 + bx + c[/tex] is located at the point [tex](-b/2a, c - b^2/4a)[/tex].

So for the function [tex]P(x) = -3x^2 + 12x + 75,[/tex] the coefficient of [tex]x^2[/tex] is -3, the coefficient of x is 12, and the constant term is 75.

Therefore, the number of items that will maximize the profit is:

x = -b/2a = -12 / 2(-3) = 2

The second derivative test is something we can use to make sure that this is a maximum. The vertex is a maximum when the second derivative of P(x) is -6, which is negative.

Since x is in thousands, the maximum profit occurs when 2,000 items are produced, and the maximum profit is:

[tex]P(2) = -3(2)^2 + 12(2) + 75 = 87[/tex]

Hence, the business will boost its benefit by making 2,000 things, and the most extreme benefit will be $87,000.

If m∠A = (4x − 2)° and m∠B = (6x − 20)°, what is the value of x?
A. 34
B. 20.2
C. 11.2
D.9

Answers

x has a value of 9. The correct response is (D).

Since the measures of angles A and B are equal, we can set them equal to each other and solve for x:

m∠A = m∠B

4x - 2 = 6x - 20

Subtracting 4x from both sides, we get:

-2 = 2x - 20

Adding 20 to both sides, we get:

18 = 2x

Dividing both sides by 2, we get:

x = 9

Therefore, the value of x is 9. Answer choice (D) is correct.

A piece of machinery is designed in a shape of a triangular prism. It must be coated in Teflon before it is placed in the machine. How many square inches of Teflon will be needed to completely to cover the machinery

Answers

We would need 168 square inches of Teflon to completely cover the triangular prism machinery.

To calculate the surface area of a triangular prism, we need to find the area of each face and then add them up. Let's assume that the triangular bases of the prism have base b and height h, and that the length of the prism is l.

The surface area of the triangular bases is (1/2)bh for each base, so the total area is (1/2)bh + (1/2)bh = bh.

The lateral surface area of the prism is the area of the three rectangular faces. Each rectangular face has length l and height h, so the total lateral surface area is 3lh.

Therefore, the total surface area of the triangular prism is

bh + 3lh

To determine how much Teflon is needed to cover the machinery, we need to know the dimensions of the triangular prism. Once we have those dimensions, we can calculate the surface area using the formula above and then use that value to determine the amount of Teflon required.

Let's say the base of the triangular prism is 4 inches and the height is 6 inches, and the length of the prism is 8 inches. Then the surface area of the triangular prism is

bh + 3lh

= (4 in. x 6 in.) + 3(8 in. x 6 in.)

= 24 in² + 144 in²

= 168 in²

if we want to estimate the population mean time for previews at movie theaters with a margin of error of minute, what sample size should be used? assume confidence.

Answers

The recommended sample size for estimating the population mean time for previews at movie theaters with a margin of error of one minute and a confidence level of 95% would be n = 1.

To determine the sample size needed to estimate the population mean time for previews at movie theaters with a margin of error of one minute, we would need to know the confidence level desired. The confidence level is the level of certainty we want to have in our estimate.

Let's assume a confidence level of 95%, which is commonly used in many statistical analyses. This corresponds to a Z-score of 1.96, which is the critical value for a 95% confidence level in a standard normal distribution.

The formula for calculating the sample size needed for estimating a population mean with a given margin of error and confidence level is:

n = ( [tex]Z^2[/tex] * [tex]σ^2[/tex] ) / [tex]E^2[/tex]

where:

n = sample size

Z = Z-score for the appropriate level of confidence

σ = standard deviation of the population (if known)

E = margin of error

Since the population standard deviation (σ) is not given, we will assume it is unknown and use a conservative estimate of 0.5 as a typical standard deviation for movie theater preview times.

Plugging in the values into the formula:

n = ( [tex]1.96^2[/tex] * [tex]0.5^2[/tex] ) / [tex]1^2[/tex]

n = (3.8416 * 0.25) / 1

n = 0.9604 / 1

n ≈ 0.9604

As sample sizes must be whole numbers, we round up to the nearest whole number to ensure we have enough sample size to meet the desired margin of error and confidence level.

To estimate the population mean time for previews at movie theaters with a margin of error of one minute and a certain confidence level, we need to use the formula for sample size calculation.

To estimate the population mean time for previews at movie theaters with a margin of error of 1 minute, you'll need to calculate the sample size. Assuming you want a certain confidence level, you'll use the following formula:

n = (Z^2 * σ^2) / E^2

Where:
- n is the sample size
- Z is the Z-score, which depends on the desired confidence level (e.g., 1.96 for 95% confidence)
- σ is the population standard deviation (you'll need to have an estimate of this value)
- E is the margin of error (1 minute in this case)

Once you have the estimated standard deviation, you can plug the values into the formula and calculate the sample size required to achieve the desired margin of error and confidence level.


Since we do not know the standard deviation of the population, we can use a conservative estimate of 5 minutes as the standard deviation. For a 95% confidence level, the z-score is 1.96. Substituting these values into the formula, we get:

n = (1.96^2 * 5^2) / (1^2) = 96.04

Rounding up, we can say that a sample size of at least 97 previews would be needed to estimate the population mean time for previews at movie theaters with a margin of error of one minute and a 95% confidence level.

how to find the slope of a normal line based on the equation of a tangent line

Answers

By following these steps, we can easily find the slope of a normal line based on the equation of a tangent line.

To find the slope of a normal line based on the equation of a tangent line.

Identify the slope of the tangent line:

Look at the equation of the tangent line, which will usually be in the form y = mx + b, where m is the slope of the tangent line and b is the y-intercept.

Extract the value of m from the equation.
Calculate the negative reciprocal:

To find the slope of the normal line, we'll need to calculate the negative reciprocal of the tangent line's slope.

The negative reciprocal of a number is found by flipping the fraction and changing the sign (from positive to negative, or from negative to positive).

For example, if the slope of the tangent line (m) is 3, the negative reciprocal will be -1/3.

If the slope of the tangent line is -2/3, the negative reciprocal will be 3/2.
The slope of the normal line:

The negative reciprocal calculated in step 2 is the slope of the normal line.

This slope will be perpendicular to the tangent line, meaning that the angle between the normal and tangent lines is 90 degrees.
