The curve that passes through the point (1,1) with a given slope is a line.

1. The equation of a line can be determined using the point-slope form of the equation, which is y - y1 = m(x - x1).

2. For the given point (1,1) and slope, the equation of the line is y - 1 = m(x - 1).

3. Substituting the given slope m for the equation, we get y - 1 = m(x - 1).

4. Simplifying the equation, we get y = mx - m + 1.

5. The equation of the line can also be written in the general form of the equation of a line, which is y = mx + b.

6. Substituting the given slope m and the y-intercept b = -m + 1, the equation of the line can be written as y = mx - m + 1.

7. The slope of the line can be determined by calculating the rise (change in y-coordinate) over the run (change in x-coordinate).

8. For the given point (1,1) and another point (x2, y2), the slope can be calculated using the formula m = (y2 - y1)/(x2 - x1).

9. For example, if the second point has coordinates (3, 4), the slope of the line can be calculated as m = (4 - 1)/(3 - 1) = 3/2.

10. The equation of the line can then be determined using the point-slope form of the equation, which is y - y1 = m(x

The amount paid for meal is obtained as $18.19.

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

Given that,

The price of the meal is $20.

The percent discount is 15%.

And, the percent tax is 7%.

Now, the final amount paid can be calculated as follows,

(20 - 15% of 20) + 7% of (20 - 15% of 20)

= (20 - 15/100 × 20) + 7/100 × (20 - 15/100 × 20)

= 17 + 7/100 × 17

= 17 + 1.19

The unit cost of all kinds of apples is $1.75 per apple thus it will be a linear function and the slope will be the same.

A linear function can be used to depict a straight line on the coordinate plane.

A linear function has the formula f(x) = ax + b, where a and b are real numbers.

As per the given,

Login buys 4 pounds (lb) and pays $7:00.Lin buys 6 lb and pays $10.50. Chita buys 2 lb and pays 3:50.

Unit cost = $7/4 = $1.75 per apple

Unit cost = $10.5/6 = $1.75 per apple

Unit cost = $3.50/2 = $1.75 per apple

Since the unit cost is the same and the unit cost represents the slope thus the graph will be a linear line as given below.

Hence "Since all varieties of apples cost $1.75 each, the function will be linear and have the same slope.".

This is False in light of the stated statement. Due to the employment of a regression line to calculate the mean of y for x that are outside the x-range of the data.

How is regression calculated?

Y = mX + b, where X is the predictive (independent) factor, m is really the approximately slope, and b is the expected intercept, is the methodology for simple linear regression.

The relationship between scattered data points in any set is shown by a regression line. When there is a linear pattern, it displays the relationship between the dependent y variable and independent x variables.

The correlation between the independent variables (IVs) and the dependent variable is described by a linear regression equation (DV). The DV for the IV values you indicate can also be predicted for new values.

Productivity is referred as the formula for the outputs divided by inputs in a given specified period of time.

All created products and services are considered as outputs. Along with labor, inputs also include capital, supplies, and energy. A common definition of productivity is the ratio of input volume to output volume. In other words, it assesses how effectively an economy uses labor and capital as production inputs to create a particular amount of output.

The simplest productivity calculation yields a straightforward ratio: Total output divided by total input is productivity. By dividing total output by total input, the labor productivity equation can be used to calculate employee productivity. Let's say your business spent 1,500 labor hours to produce $80,000 worth of goods or services (input). To determine the labor productivity of your business, divide 80,000 by 1,500, which results in the number 53.

What is standard deviation?

A measure of a group of values' variance or dispersion in statistics is called the standard deviation. When the standard deviation is low, the values are more likely to fall within a narrow range, also known as the expected value, whereas when the standard deviation is high, the values tend to be closer to the mean.

The lowercase Greek letter sigma, which stands for the population standard deviation, or the Latin letter s, which stands for the sample standard deviation, are most frequently used in mathematical equations and texts to represent standard deviation. Standard deviation is also sometimes referred to as SD.

suppose that in a random sample of size 100, the standard deviation of the sampling distribution of the sample proportion is 0.08.

Since we know the weights from the population, we can find the population mean.

The required slope of a line perpendicular to the line is -1/6.

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 can be used to gauge how steep it is.

The slope is theoretically determined as "rise over run" (change in y divided by change in x).

So, we have the equation:

3x+18y=-486

Now, get the slope as follows:

3x+18y=-486

18y = -3x - 486

your x is going to be:115

The duration was 4.25 hours.

The parts cost 167.

Cost in full: 655.75

so the price per hour is x.

As a result, when you write your equation, the total number of hours (multiplied by the cost per hour) will be added to the cost of the parts, and the sum of these two amounts will be your total cost.

In order to solve the problem, you must deduct the cost of each component from the total cost. This should give you the following result: 4.25x = 488.75

The shape of the cross section of a triangular pyramid sliced by a plane that is perpendicular to its base is triangle.

The non-empty intersection of a solid body in three dimensions with a plane, or its equivalent in higher dimensions, is referred to as a cross section in geometry and science. Many parallel cross-sections are produced when an object is sliced. The boundary of a cross-section in three dimensions that is parallel to two of the axes, that is, parallel to the plane determined by these axes, is sometimes referred to as a contour line.

A triangle-shaped pyramid essentially has a triangle-shaped base. The cross section formed when an imaginary line is produced to cut through perpendicular to the base will still have a triangular orientation, but it will be smaller than it was when the pyramid's original triangular orientation or sides were there.

The value of the equation A = n³ ( 2n )⁻² is given by A = ( n / 4  )

What are the laws of exponents?

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ  = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the equation be represented as A

Now , the value of A is

A = n³ ( 2n )⁻²

On simplifying the equation using the laws of exponents , we get

The value of A = n³ / ( 2n )²

Taking the powers to the value of 2n , we get

The value of A = n³ / 4n²

On dividing the numerator and denominator by n² , we get

The value of A = n / 4
