A hendecagon is graphed on a coordinate grid and then dilated by a scale factor of 5 with the origin as the center of dilation. Vertex A of
the original hendecagon is located at (-8, 7). Write the ordered pair
that represents the location of vertex A after the dilation.
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).

heteroscedasticity of residuals in regression suggests that there is a. lack of independence in successive errors. b. nonnormality in the errors. c. multicollinearity among the predictors. d. nonconstant variation in the errors.
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.

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]

Prediction values are meaningful for all X-values that are realistic in the context of the original data set. B. Prediction values are meaningful only for x-values that are not included in the original data set. C. Prediction values are meaningful only for X-values in (or close to the range of the original data.
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.

the yield of good chips during a certain step in silicon processing of integrated circuits averages 89%. this processing step is considered to be in statistical control. the number of chips per wafer is 156. determine the center line, lcl, and ucl for the p chart that would be used for this processing step.
The center line, LCL, and UCL for the p chart that would be used for this processing step are 89%, 88.3%, and 89.7%, respectively.
The center line of a p chart is the average yield of good chips during a processing step, and is calculated as follows:
Centerline = average yield of good chips = 89%
The lower control limit (LCL) and upper control limit (UCL) for a p chart are calculated using the following equations:
LCL = average yield of good chips - 3 × standard deviation
UCL = average yield of good chips + 3 × standard deviation
To calculate the standard deviation, we need to know the number of chips per wafer (156 in this case). The standard deviation is calculated using the equation:
standard deviation = √(p × (1 - p) / n)
where p is the average yield of good chips (89% in this case), (1 - p) is the average yield of defective chips (11% in this case), and n is the number of chips per wafer (156 in this case).
Plugging the values for p, (1 - p), and n into the equation gives us:
standard deviation = √(0.89 × 0.11 / 156) = 0.0256
Substituting the standard deviation into the equations for the LCL and UCL gives us:
LCL = 89% - 3 × 0.0256 = 88.3%
UCL = 89% + 3 × 0.0256 = 89.7%

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
(0.44 – 0.4)/0.4 = 0.1/0.4 = 0.25 = 400 parts per thousand.

This set of numbers is 63, 53, 20, 10. The current average is 36.5.
Adding 9 to that number makes it equal 155. To find the average, we now have to divide 155 by 5(because thats how many numbers there is.
155/5=31

la pyramide du louvre
D'après ce que je sais. La pyramide du Louvre (Pyramide du Louvre) est une grande structure de verre et de métal conçue par l'architecte sino-américain I. M. Pei. La pyramide se trouve dans la cour principale (Cour Napoléon) du Palais du Louvre à Paris, entourée de trois pyramides plus petites. La grande pyramide sert d'entrée principale au musée du Louvre. Achevé en 1988 dans le cadre du projet plus large du Grand Louvre, il est devenu un point de repère de la ville de Paris.
