Based on the regression equation. which is the best prediction for the price of a 75-pound container of detergent?

Answer:

ℎ(−5) is −14.

Step-by-step explanation:

To find the value of ℎ(−5), we plug −5 in for x in the expression for ℎ(x):

ℎ(−5) = −3|−5 − 1| + 4

To evaluate the absolute value, we need to find the distance between −5 and 1 on the number line. Since the absolute value function is always non-negative, the distance between −5 and 1 will be positive.

To find the distance between −5 and 1, we subtract the smaller number from the larger number:

|−5 − 1| = |−6| = 6

Now we can plug this value into the expression for ℎ(−5) to find its value:

ℎ(−5) = −3 * 6 + 4

ℎ(−5) = −18 + 4

ℎ(−5) = −14

Therefore, the value of ℎ(−5) is −14.

The integer numbers that will be repeating in the quotient is 36, the decimal representation of the fraction is 0.3636...

When 8 is divided by 22 we get the fraction 8/22 , when simplified this fraction gives 4/11 .

Now we will divide the numerator by the denominator we get:

4 ÷ 11 = 0.363636...

Thus, it is a repeating decimal .

Hence the numbers 36 will constantly repeat itself.

A quotient is the result of dividing two numbers. The quotient is a mathematical phrase that can also be used to refer to the integer component of a division, fraction, or ratio.

The term "quotient" has been used in many mathematical disciplines to depict structures generated by disassembling larger structures. Given a set with an equivalence relation specified on it, a "quotient set" having particular equivalence classes as items can be formed.

A quotient group is generated by dividing a group into numerous comparable co-sets, and a quotient space is formed by dividing a vector space into numerous comparable linear subspaces.

The cost of the labor per hour is 115 hours.

The equation is going to be:

4.25x + 167 = 655.75

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

After that, divide 4.25 by each side as you normally would.

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

Therefore , the value of A = n / 4

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

Step-by-step explanation:

The rate of change of the linear function represented by the table is a = 4.

A general linear function is written as:

f(x) = a*x + b

Where a is called the slope and is also the rate of change of the function, and b is the y-intercept.

If we know two points on the line, (x₁, y₁) and (x₂, y₂), then the rate of change can be computed with the following formula:

a = (y₂ - y₁)/(x₂ - x₁)

In this case we have a table with some points on that line, we can use any two we want.

For example, I will use the first two, these are:

(-4, -21) and (-3, -17)

Then the rate of change of the linear function is given by:

a = (-17 + 21)/(-3 + 4) = 4/1 = 4

The rate of change is a = 4.

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.

Given that, Paul's family picks 22 pounds of apples.

They pick a bag of Honeycrisp apples weighs 18 pounds.

Assume that they take Golden Delicious apples with weight w.

Then the total weight of the bag is 18 + w.

Answer:

To write and solve an inequality that can be used to determine the number of 50-kilogram crates that can be loaded into the shipping container, we need to first find the total weight of the crates that can be loaded into the container. The maximum weight that can be loaded into the container is 27500 kilograms, and other shipments weighing 9500 kilograms have already been loaded, so the total weight of the crates that can be loaded is 27500 kilograms - 9500 kilograms = 18000 kilograms.

Next, we need to divide the total weight of the crates that can be loaded by the weight of each crate to find the number of crates that can be loaded. Since each crate weighs 50 kilograms, the number of crates that can be loaded is 18000 kilograms / 50 kilograms = 360 crates.

To express this as an inequality, we can use the following equation:

x <= 360

This inequality states that the number of crates that can be loaded into the shipping container (x) must be less than or equal to 360. Therefore, the number of 50-kilogram crates that can be loaded into the shipping container is x <= 360.

The amount of investment after compound interest will be $8183.24.

Compound interest is the addition of interest to the principal sum of a loan or deposit or interest on interest plus interest.

In finance and economics, interest is the payment of an amount above the repayment of the principal sum by a borrower or deposit-taking financial institution to a lender or depositor at a specific rate by a borrower or depositor. It differs from a fee that the borrower may pay to the lender or a third party.

The formula calculates compound interest is calculated by the formula,

[tex]A=P(1+\dfrac{r}{100})^{nt}[/tex]

Here,

A = Amount

P = Principle amount

r = rate of interest

n= Number of times amount compounded

t = time

The compounded amount will be calculated as,

A = 5575 ( 1 + 0.0325 )¹²
