What is 1/2÷3/4 equal ?

The samples in the first proposal are independent, while the samples in the second proposal are dependent.

In the first proposal, where the manufacturer randomly samples 10 different dealerships for each set of sales numbers (last year and 15 years ago), the samples are independent. This is because the selection of dealerships for one set of sales numbers does not affect or influence the selection of dealerships for the other set of sales numbers. Each dealership is chosen randomly and independently for each set.

On the other hand, in the second proposal, where the manufacturer randomly samples 10 dealerships for both sets of sales numbers, the samples are dependent. This is because the selection of dealerships for one set of sales numbers is directly tied to the selection of dealerships for the other set of sales numbers. The same 10 dealerships are chosen for both sets, so the samples are not independent.

The choice between independent and dependent samples can have implications for statistical analysis. Independent samples allow for direct comparisons between the two sets of sales numbers, while dependent samples may introduce potential bias or confounding factors due to the shared dealership selection.

Answer: x=39

Step-by-step explanation:

You would subtract 107 and 68 to get your answer. Therefore, your answer would be 39.

Answer:

X=39

Step-by-step explanation:

180 - 107 = 73

180 - 68 = 112

73 + 68 = 141

180 - 141 = 39

The amount of interest paid so far (over the last 10 years) is $78,636 and the amount of interest you will pay over the life of the new loan is $99,999.17.

In order to find out how much interest has been paid so far, we need to find out how much the initial loan was. The down payment made on the home was 10%, so:

Down payment = 10% of $110,000

Down payment = 0.10 × $110,000 = $11,000

So the initial loan was the difference between the price of the home and the down payment:

Initial loan = $110,000 - $11,000

Initial loan = $99,000

Now we can use the loan balance and the initial loan to find out how much of the loan has been paid off in 10 years:

Amount paid off so far = Initial loan - Loan balance

Amount paid off so far = $99,000 - $88,536

Amount paid off so far = $10,464

Now we can find out what percentage of the initial loan that is:

Percent paid off so far = (Amount paid off so far / Initial loan) × 100

Percent paid off so far = ($10,464 / $99,000) × 100

Percent paid off so far = 10.56%

So the amount of interest paid so far is the total payments made minus the amount paid off:

Interest paid so far = Total payments - Amount paid off

Interest paid so far = ($99,000 × 0.09 × 10) - $10,464

Interest paid so far = $89,100 - $10,464

Interest paid so far = $78,636

So the interest paid so far is $78,636.

The life of the new loan is the remaining 20 years of the original 30-year loan. The interest rate is still 9%. To find out how much interest will be paid over the life of the new loan, we can use an online loan calculator or a spreadsheet program like Microsoft Excel.

Using an online loan calculator with a loan amount of $88,536, a term of 20 years, and an interest rate of 9%, we get the following result:

Total payments over life of loan = $188,535.17

Principal paid over life of loan = $88,536.00

Interest paid over life of loan = $99,999.17

So the interest paid over the life of the new loan is $99,999.17.

Thus the answer to your problem is, 21

Answer:

3, because \(y=-\frac{1}{2}x+9\).

Step-by-step explanation:

Looking at this graph, we can start to determine the equation for it.

The y-intercept of this graph is 9, therefore there will be a constant of 9.

We can find the slope by looking at rise over run. It vertically travels -1 for every 2 horizontally. So the slope is \(-\frac{1}{2}\).

Making this into an equation gets us  \(y=-\frac{1}{2}x+9\).

Now we can substitute 12 into this equation as x.

\(y=-\frac{1}{2}(12)+9\\ y=-6+9\\y=3\)

Step-by-step explanation:

Since none of the 13 classmates had been given math homework between the original survey and Kelly's second survey, the sum of the values in the second data set is the same as the sum of the values in the original data set. Therefore, the change in the means can be determined without calculating the mean of either data set by considering the number of data points in each set.

Since both data sets have the same number of data points, the change in the means will be zero. This is because the mean is calculated by dividing the sum of the values by the number of data points, and since the sum of the values is the same in both data sets, the means will also be the same.

In other words, if the mean of the first data set is x, then the sum of the values in the first data set is 13x (since there are 13 classmates), and the sum of the values in the second data set is also 13x (since none of the values have changed). Therefore, the mean of the second data set will also be x, and the change in the means will be zero.

the standard matrix of the linear transformation T: ℝ² → ℝ², which first reflects points through the line x₂ = -x₁ and then reflects points through the origin, is:

[ -1  0 ]

[  0  1 ]

To find the standard matrix of the linear transformation T: ℝ² → ℝ², we can determine how the basis vectors of ℝ² transform under the given transformation.

The standard basis vectors of ℝ² are:

e₁ = (1, 0) (corresponding to the x-axis)

e₂ = (0, 1) (corresponding to the y-axis)

First, let's apply the reflection through the line x₂ = -x₁:

For e₁ = (1, 0), the reflection through the line x₂ = -x₁ maps it to (-1, 0).

For e₂ = (0, 1), the reflection through the line x₂ = -x₁ maps it to (0, 1).

Next, let's apply the reflection through the origin:

For (-1, 0), the reflection through the origin keeps it the same (-1, 0).

For (0, 1), the reflection through the origin keeps it the same (0, 1).

Now, we have the transformed basis vectors:

T(e₁) = (-1, 0)

T(e₂) = (0, 1)

The cournot theory of oligopoly is based on the assumption that each firm believes that rivals will keep their output constant if it changes its output.

The Cournot theory of oligopoly is an economic model that analyzes the behavior of firms in an oligopolistic market structure. It is named after the French economist Antoine Augustin Cournot.

In the Cournot model, each firm in the market assumes that its rivals will keep their output constant if it changes its own output. This assumption is based on the idea that firms make strategic decisions regarding their production levels, taking into account the likely responses of their competitors.

Under the Cournot model, firms choose their output levels simultaneously, considering the current market conditions and their expectations of how their competitors will react. Each firm acts as a quantity-setter, determining its production quantity based on its own cost structure, market demand, and beliefs about how its rivals will behave.

The assumption that rivals will keep their output constant if one firm changes its output is a simplification used in the Cournot model. It implies that firms do not engage in immediate or aggressive reactions to changes in their competitors' output levels. Instead, they make decisions based on the expectation that their rivals' production decisions will remain unchanged.

By making these assumptions, the Cournot model allows economists to analyze the equilibrium outcomes and market shares that arise in oligopolistic markets. It provides insights into how firms' interdependent behavior affects prices, quantities, and overall market outcomes.

It is important to note that the Cournot model is a simplified representation of real-world oligopoly markets, and the actual behavior of firms may deviate from these assumptions. Nonetheless, the model serves as a useful tool for understanding strategic interactions among firms in oligopolistic industries.

For a uniform distribution random variable X, the probability that the random variable has a value between 0.6 and 2.1 is equals to 0.1875. So, option(a) is right one.

The uniform distribution is defined as a continuous probability distribution and the events are equally likely to occur. In other words in this distribution every possible outcome has an equal probability. There is a uniform distribution of variable. Let the random variable be denoted by X be uniformly distributed. The above figure shows uniform density curve for X. That is \( X \: \tilde \: \: U( 0, 8) \).

Probability density function is f(x) = \(\frac{ 1}{8} = 0.125\)

We have to determine probability that the random variable has a value between 0.6 and 2.1, P(0.6 ≤ X ≤ 2.1). So, required probability is P(0.6 ≤ X ≤ 2.1) = \(\int_{0.6}^{2.1} f(x) dx \).

\(= [ 0.125x ]_{0.6}^{2.1}\)

= 0.125 ( 2.1 - 0.6)

= 0.125 ( 1.5)

= 0.1875

Answer:

B) 174

Step-by-step explanation:

30+6*2 because she already has 30 made and 2 dozen per 6 hours. So to find how any dozen in the 6hrs you do 2*6 = 12. So 12 dozen in 6hrs. 1 dozen is 12 cookies. To find how much cookies in 12 dozen you do 12*12 = 144. Now you do 144+30 because she bakes 30 earlier and she will bake 144 in those 6 hours. 144+30 = 174. So Frida will have 174 cookies. So the answer is B) 174.

The x-value of where the beam should be placed is X = (x1+x2)/2.

Given: the distance between the two trusses is 2 feet and the reinforcement beam will extend from one truss to the other.

We can set up an equation using the distance formula to determine the x-value of where the beam should be placed.

The distance formula is: d = √((x2 - x1)² + (y2 - y1)²)

Let's assume that the trusses are located at point (x1, y1) and (x2, y2) and the beam is located at point (x, y).

We know that the distance between the trusses is 2 feet, so we can set d = 2.

We can use the coordinates of the trusses and the point where the beam is located to set up the equation:

d = √((x2 - x1)² + (y2 - y1)²) = 2

Since the trusses are located on the same line and only the x-coordinate changes, we can assume that y1=y2

Therefore the equation can be simplified to √((x2 - x1)²) = 2

Square both sides: (x2 - x1)² = 4

x2 - x1 = 2

Now we know that the difference between the x-coordinates of the two trusses is 2 feet.

So, to find the x-value of the point where the reinforcement beam should be placed, we can take the average of the x-coordinates of the two trusses.

x = (x1+x2)/2

We don't know the values of x1 and x2, so we can't solve for x. But we know that the reinforcement beam should be placed exactly in the middle of the trusses.

Thus, The x-value of where the beam should be placed is X = (x1+x2)/2.

In a radial distribution function, the nodes represent the distances between atoms in a crystalline material.

The radial distribution function (RDF) is a measure of the probability of finding an atom at a given distance from a reference atom. It provides information about the arrangement and spatial distribution of atoms in a material.

The nodes in the RDF graph correspond to specific distances from the reference atom. These distances represent the separation between atoms and are typically measured in terms of interatomic distances or bond lengths. The heights or values of the RDF at these nodes indicate the likelihood of finding an atom at that particular distance from the reference atom.

By analyzing the nodes in the radial distribution function, researchers can gain insights into the atomic structure, coordination, and bonding characteristics of a material, which are essential for understanding its physical and chemical properties.
