Step-by-step explanation:

To determine the total price of the phone including taxes, we need to first calculate the amount of sales tax by multiplying the price of the phone by the sales tax rate:

Sales tax = Price of phone * Sales tax rate

Sales tax = $39 * 5%

Sales tax = $1.95

Next, we can calculate the total price of the phone including taxes by adding the amount of sales tax to the price of the phone:

Total price including taxes = Price of phone + Sales tax

Total price including taxes = $39 + $1.95

Total price including taxes = $40.95

Rounded to the nearest cent, the total price of the phone including taxes is $41.00.

The total cost of the skateboard if Loui has to pay a state sale tax of 6. 25% is 72.26.

As per the given data, Loui wants to buy a skateboard that has an original price of 79.91, will be discounted 12 %, and will have a sales tax of 6.25 %.

When performing the calculations, remember to convert percent to decimal form and if needed, round to two decimal places since money must be rounded to the nearest cent.

First, we need to find the amount of the discount and then find the sale price (the price after the discount):

Sale price:

Original price - Amount of discount = 79.91 - 11.9 = 68.01

Now that we have the sale price, we can find the amount of tax and then the total cost:

Amount of tax  = ( sale price) × (sales tax percent)

[tex]$$\begin{aligned}& =\ 68.01 \times \ 0.0625 \\& \approx \ 4.25 \end{aligned}$$[/tex]

Total cost = sale price + amount of tax

The correct answer is (C) Prediction values are meaningful only for X-values in (or close to the range of the original data.

A regression line is a statistical model that is used to make predictions about the value of a dependent variable (Y) based on the value of an independent variable (X). The regression line is based on a sample of data, and it is typically used to make predictions about the population from which the sample was drawn.

The validity of the predictions made using a regression line depends on the assumptions that were used to create the model. One of these assumptions is that the relationship between X and Y is linear, which means that the predictions are only meaningful for X-values that are within (or close to) the range of the original data. If the X-value is outside this range, the prediction may not be accurate because the model may not accurately represent the underlying relationship between X and Y.

Therefore, to provide meaningful predictions for Y, the values of X should be within (or close to) the range of the original data.

Based on the correlation coefficient from the technology data given, the data has a strong negative association.

The correlation coefficient is defined as a statistical measure of the strength of a linear relationship that exists between two variables.

The possible range of values for correlation coefficient is from -1.0 to 1.0. This tells us that the values cannot be more than 1.0 nor be less than -1.0.

Thus, a correlation coefficient of -1.0 shows a perfect negative correlation, while a correlation coefficient of 1.0 shows a perfect positive correlation.

We are given a correlation coefficient of r = -0.9478.

Now, the closer the negative correlation is to -1 indicates a strong negative correlation while the farther it is from -1 indicates a weak negative correlation.

Thus, we can conclude that in this case where the  negative correlation is closer to -1 than farther, it can be said to be a strong negative correlation.

Answer: The two expressions that represent the perimeter of the rectangular pool include the following:

A. x + 3x + 1 + x + 3x + 1

E. 8x + 2

How to calculate the perimeter of a rectangle?

Mathematically, the perimeter of a rectangle can be calculated by using this equation;

P = 2(L + x)

Where:

P represents the perimeter of a rectangle.

L represents the length of a rectangle.

x represents the width of a rectangle.

Since the length is 1 more than 3 times the​ width, we have;

Length, L = 3x + 1

Therefore, the two expressions for the perimeter of this rectangle is given by:

P = 2(3x + 1 + x) = x + 3x + 1 + x + 3x + 1

P = 2(4x + 1) = 8x + 2

Next, we would determine the total cost as follows;

P = 8x + 2

P = 8(20) + 2

P = 162 feet.

Total cost = 1.86 × 162

Option (d) is correct. Heteroscedasticity of residuals in regression suggests that there is a non constant variation in the error.

Heteroscedasticity means unequal scatter. In regression analysis, we talk about heteroscedasticity in the context of the residuals or error term. Heteroscedasticity is a systematic change in the spread of the residuals over the range of measured values. Heteroscedasticity is a problem because ordinary least squares regression assumes that all residuals are drawn from a population that has a constant variance that is heteroscedasticity. the residuals should have a constant variance. Heteroscedasticity is also called as heteroskedasticity. It occurs more often in datasets that have a large range between the largest and smallest observed values. This explains Heteroscedasticity.

g sio2 is always 0.4 mg too high regardless of the weight of the sample taken for analysis. The relative error in parts per thousand would be 400.

This is because the relative error is calculated by taking the difference between the actual value and the measured value, and dividing this by the actual value.

In this case, the actual value is 0.4 mg and the measured value is

0.4 mg + (10% x 0.4 mg) = 0.44 mg. Thus the relative error is

Answer: The ordered pair that represents the location of vertex A after the dilation is (-40, 35).

Step-by-step explanation:

How do we dilate a figure with the origin as the center of dilation?

To dilate a figure with the origin as the center of dilation, we multiply the coordinates of each point by the scale factor. This has the effect of stretching or shrinking the figure, depending on whether the scale factor is greater than or less than 1.

To dilate a figure by a scale factor of 5 with the origin as the center of dilation, we need to multiply the x- and y-coordinates of each point in the figure by 5.

So, to find the coordinates of vertex A after the dilation, we start with the coordinates of vertex A before the dilation, which are (-8, 7).

Then, we multiply the x-coordinate by 5 to get (-8)5 = -40, and we multiply the y-coordinate by 5 to get (7)5 = 35.

Vertex A is located at (-8, 7). If we multiply these coordinates by 5, we get (-40, 35). Therefore, the coordinates of vertex A after the dilation are (-40, 35).

After the dilation, the ordered pair that depicts where vertex A is located is (-40, 35).

How can we increase a figure so that the origin serves as the dilation center?

We multiply the coordinates of each point by the scale factor to dilate a figure with the origin as the center of dilation. Depending on whether the scale factor is larger than or less than 1, this has the effect of either expanding or shrinking the figure.

The x- and y-coordinates of each point in the figure must be multiplied by 5 in order to dilate it by a scale factor of 5, with the origin serving as the centre of dilation.

Thus, we begin with the coordinates of vertex A before the dilation, which are, in order to obtain the coordinates of vertex A after the dilation (-8, 7).

The x-coordinate is then multiplied by 5 to get (-8)5 =-40, while the y-coordinate is multiplied by 5 to get (7)5 = 35.

Vertex A can be observed at (-8, 7). These coordinates are multiplied by 5 to get (-40, 35). As a consequence, vertex A's coordinates after dilation are (-40, 35).
