The Z score for a sample mean being 180  is -2.50.

To calculate the z-score for a sample mean x = 180 with a population mean (μ) of 200 and a standard deviation (σ) of 24, we need to use the following formula:

z = (x - μ) / (σ / √n)

In this case, x = 180, μ = 200, σ = 24, and n = 9.

Step 1: Subtract the population mean from the sample mean: (180 - 200) = -20.
Step 2: Divide the standard deviation by the square root of the sample size: (24 / √9) = 24 / 3 = 8.
Step 3: Divide the result from Step 1 by the result from Step 2: (-20) / 8 = -2.5.

The z-score for a sample mean x = 180 is -2.50.

For the first payment, the interest payment is $1,330 and the principal repayment is $2,715.39.

To calculate the annual loan payments, we need to use the formula for an amortized loan:

Payment = (Loan Amount * Interest Rate) /\((1 - (1 + Interest Rate)^{-Number of Payments}\)

Substituting the values given in the problem, we get:

Payment = ($19,000 * 0.07) / \((1 - (1 + 0.07)^{-5}\)

Calculating this out gives us a payment of $4,045.39 per year.

To calculate the amount of the first payment that will be applied to interest and principal repayment, we need to use the following formula:

Interest Payment = Remaining Balance * Interest Rate

Principal Payment = Payment - Interest Payment

We can use these formulas to calculate the interest and principal payments for the first year. First, we need to find the remaining balance after the first payment is made. We can do this using the following formula:

Remaining Balance = Initial Balance - Principal Payment

Plugging in the values given in the problem, we get:

Interest Payment = $19,000 * 0.07 = $1,330

Principal Payment = $4,045.39 - $1,330 = $2,715.39

Remaining Balance = $19,000 - $2,715.39 = $16,284.61

So, for the first payment, the interest payment is $1,330 and the principal repayment is $2,715.39.

The eigenvectors of AAH are called the left-singular vectors of A and the eigenvectors of AHA are the right-singular vectors of A . They are called this way because of their use in singular value decomposition. Say A=UΣVH , then the columns of U are the left-singular vectors and the columns of V are right-singular vectors.

We know that the non-zero eigenvalues of AAH  and AHA are the same, they are the squares of the singular values of A . A singular of value of A is a value σ such that Av=σu   AHu=σv where u is a left-singular vector and vs a right-singular vector. This can be taken as the definition of singular value, left-singular vector (which is an eigenvector of AAH) and right-singular vector (which is an eigenvector of AHA).the left-singular and right-singular vector pair works with AAH and AHA

Based on the calculations, the value of the given prefix expression is equal to 2205.

The preorder traversal of a tree (T) are typically used in discrete mathematics to determine the value of a prefix expression on a specific expression tree.

For the preorder traversal of this tree (T), we would start from the right most expression:

Prefix expression = * + 3 + 3 ↑ 3 + 3 3 3

Prefix expression = * + 3 + 3 ↑ 3 6 3

Prefix expression = * + 3 + 3  3⁶  3

Prefix expression = * + 3 3 729 3

Prefix expression = * + 3 732 3

Prefix expression = * 735 3   ⇒ 735 × 3

Answer:

The power in repeated multiplication form is (-2)*(-2)*(-2)

The value of the power is  -8

=====================================================

Reason:

Exponents represent repeated multiplication. The small number up top is the exponent that tells us how many copies of the base to multiply

In this case, the exponent 3 tells us we have 3 copies of "-2" multiplied together to get (-2)*(-2)*(-2)

This simplifies to -8

What is straight line method ?

The straight-line method is a common method of calculating depreciation expense for an asset over its useful life. This method assumes that the asset will lose an equal amount of its value each year over its useful life, and therefore the depreciation expense for each year is the same.

To calculate the depreciation expense using the straight-line method, you need to know the cost of the asset, its estimated useful life, and its estimated salvage value (the amount it's expected to be worth at the end of its useful life).

The formula for depreciation expense using the straight-line method is:

Depreciation expense = (Cost of asset - Salvage value) / Useful life

For example, if a company purchases a machine for $10,000, expects it to have a useful life of 5 years, and has an estimated salvage value of $2,000, the depreciation expense using the straight-line method would be:

Depreciation expense = ($10,000 - $2,000) / 5 = $1,600 per year

Using this method, the book value of the asset at the end of each year can be calculated by subtracting the total accumulated depreciation from the cost of the asset.

The straight-line method of depreciation assumes that the asset loses an equal amount of its value each year over its useful life. Therefore, we can determine the book value at the end of the third year by subtracting the total accumulated depreciation for three years from the original cost of the asset.

Total accumulated depreciation after 3 years:

3 x $595 = $1,785

Book value at the end of the third year:

$3,500 - $1,785 = $1,715

Therefore, the correct answer is (B) $1,715.

Step-by-step explanation:

let the numbers be x and y

but y = 3x

3x - x = 10

2x = 10

x = 5

Answer:

\(\Large \boxed{\sf 15 \ and \ 5}\)

Step-by-step explanation:

Let the first number be x.

Let the second number be y.

x is 3 times y.

Difference of x and y is 10.

\(x=3y\)

\(x-y=10\)

Put x as 3y in the second equation.

\(3y-y=10\)

Combine like terms.

\(2y=10\)

Divide both sides by 2.

\(y=5\)

Plug y as 5 in the first equation.

\(x=3(5)\)

Multiply.

\(x=15\)

The two numbers are 15 and 5.

Answer:

No, not a factor.

Step-by-step explanation:

By solving for (x-4) and getting x = 4, if we take that value and subtititute it into the original function, it should result in 0 IF it was a factor of the original function.

After substituting it in, you get a vbalue other than 0, meaning that by the factor theorem, (x-4) is not a factor.

We need to know about the concept of dilation to understand the question.

The coordinate of C' will be 1/2 times it's original coordinate.

Dilation is a form of transforming an object by changing it's size or shape by either increasing or decreasing it's dimensions with the use of scaling factors.For example if a shape is said to have been dilated by a factor of 2 it simply means that the object has been doubled it's size.The coordinates of the new object will be twice of the original coordinates. So if one of the coordinate was (1,1) then the coordinates of that point will be (2,2) after dilation.

Here in the question it is said that ABCD has been dilated by a factor of 1/2, so to find the new coordinates of the point C' we will have to multiply the original coordinates at C by 1/2.

Approximately 19.9919 pounds of bananas are removed from the display table during the first 2 hours the store is open.

The function has a constant term 10, which represents the minimum rate of banana removal even if no customers are present.

The second function is g(t), which models the rate at which bananas are added to the display table.

Now, to answer the question, we need to find out how many pounds of bananas are removed from the display table during the first 2 hours. We can do this by integrating the function f(t) from 0 to 2, which gives us the total amount of bananas removed during this time interval. Using the integral notation, we have:

Total amount of bananas removed = ∫₀² f(t) dt

Using the formula for f(t), we can evaluate this integral as follows:

∫₀² [10 + (0.81)sin(100t)] dt = [10t - (0.81/100)cos(100t)] from 0 to 2

Plugging in the limits of integration, we get:

[10(2) - (0.81/100)cos(200)] - [10(0) - (0.81/100)cos(0)] = 20 - 0.0081 ≈ 19.9919 pounds

All of the ingredients are given in amounts enough to make 3 dozen cookies. But we want to know how much of them are required to make 4 dozen cookies.

Following the proportions rules, if we want 4 and have 3, the adjustment must be 4 / 3, or four thirds.

For example, if you use 6 eggs for 3 dozen cookies, you now need 6*4/3=8 eggs.

This proportion will be applied to all of the ingredients as follows.

We needed 1 and 3/4 cups of vegetable oil. Expressing that as a single fraction:

The new amount of vegetable oil will be:

We now need 2 and 1/3 cups of vegetable oil.

It's required to use 2 and 1/4 teaspoons of almond extract. Expressing as a single fraction:

The new amount of almond extract is:

Now we need exactly 3 teaspoons of almond extract.

Finally, the recipe required 2 and 1/2 teaspoons of cinnamon. The equivalent fraction is:

This means the new amount of cinnamon is:

We now need 3 and 1/3 teaspoons of cinnamon.

Summarizing, for 4 dozen cookies we need:

2 and 1/3 cups of vegetable oil

A correlation does not simply mean that two or more variables are present together. The statement is false.

Correlation can be positive, negative, or zero.
Positive correlation means that as one variable increases, the other variable also increases. For example, there is a positive correlation between the amount of studying and exam scores.

Negative correlation means that as one variable increases, the other variable decreases. For example, there is a negative correlation between the number of hours spent watching TV and physical activity levels.

Zero correlation means that there is no relationship between the variables. For example, there is zero correlation between the number of pets someone owns and their height.

It's important to note that correlation does not imply causation. Just because two variables are correlated does not mean that one variable causes the other to change.

To summarize, a correlation measures the statistical relationship between variables, whether positive, negative, or zero. It is not simply the presence of two or more variables together. The statement is false.
