The unknown number in the statement is 64/3.

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.

According to the banker's rule, Amber can afford to borrow a maximum of $96,900.

The banker's rule is a guideline used by some lenders to determine the maximum amount that an individual can borrow based on their annual income.

According to the banker's rule, the maximum amount that can be borrowed is typically a multiple of the borrower's annual income.

The exact multiple used in the banker's rule may vary depending on the lender and the borrower's financial situation, but a common multiple used is 3.

Therefore, to calculate the amount that Amber can afford to borrow using the banker's rule, we can multiply her annual income by 3.

Given that Amber makes $32,300 annually, we can calculate the amount that can be borrowed using the banker's rule as follows:

Maximum amount that can be borrowed = Annual income * Banker's rule multiple

Maximum amount that can be borrowed = $32,300 * 3

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

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.

Hannah needs to earn an annual interest rate of approximately 5.88% to reach $1,000,000 in 25 years.

To determine the rate Hannah needs to earn to reach $1,000,000 in 25 years, we can use the future value formula for an annuity:

[tex]FV = Pmt * [(1 + r)^n - 1] / r[/tex]

where:

FV = future value (in this case, $1,000,000)

Pmt = periodic payment (in this case, Hannah's annual contribution)

r = annual interest rate

n = number of periods (in this case, 25 years)

Hannah will deposit $3,000 this year and increase her deposits by $750 each following year. So her annual contributions will be:

Year 1: $3,000

Year 2: $3,750

Year 3: $4,500

...

Year 25: $21,750

To simplify the calculation, we can use the average annual contribution over the 25-year period, which is:

[tex][(3,000 + 21,750) / 2] = $12,375[/tex]

Now we can plug in the values into the formula and solve for r:

[tex]1,000,000 = 12,375 * [(1 + r)^25 - 1] / r[/tex]

Multiplying both sides by r and dividing both sides by 12,375, we get:

[tex]r x (1 + r)^25 = 120.75[/tex]

We can solve for r using trial and error, or using a financial calculator or spreadsheet. Using trial and error, we can try different interest rates until we find the one that makes the equation true. One possible method is to start with a reasonable guess, such as 6%, and adjust up or down until we get close to 120.75. After a few iterations, we find that:

r = 5.88%

Therefore, Hannah needs to earn an annual interest rate of approximately 5.88% to reach $1,000,000 in 25 years, assuming she deposits $3,000 this year and increases those deposits by $750 each following year.

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.

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

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.

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

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.
