Answers
Answer:
D. 4
Step-by-step explanation:
The Dilation can be measured by vertices A. it started at (1, -2) but went to (4, -8). 1 x 4 = 4 and -2 x 4 = -8

Polygon ABCD with vertices at A(−4, 6), B(−2, 2), C(4, −2), and D(4, 4) is dilated using a scale factor of one eighth to create polygon A′B′C′D′. If the dilation is centered at the origin, determine the vertices of polygon A′B′C′D′.
Answers
Answer:
The third option
Step-by-step explanation:
Multiply all coordinates by 1/8 or 0.125
So
A(−4, 6) → A(-0.5, 0.75) when both points are multiplied by 0.125
B(−2, 2) → B(-0.25,0.25) when both points are multiplied by 0.125
We could go on and find all the values but the third option is the only one that has the right values so it has to be correct
Vertex A′: (x', y') = (kx, ky) = (1/8) * (-4,6) = (-1/2, 3/4)
Therefore, the coordinates of A′ are (-1/2, 3/4)
Vertex B′: (x', y') = (kx, ky) = (1/8) * (-2,2) = (-1/4, 1/4)
Therefore, the coordinates of B′ are (-1/4, 1/4)
Vertex C′: (x', y') = (kx, ky) = (1/8) * (4,-2) = (1/2, -1/4)
Therefore, the coordinates of C′ are (1/2, -1/4)
Vertex D′: (x', y') = (kx, ky) = (1/8) * (4,4) = (1/2, 1/2)
Therefore, the coordinates of D′ are (1/2, 1/2)
So, the vertices of dilated polygon A′B′C′D′ are (-1/2, 3/4), (-1/4, 1/4), (1/2, -1/4), and (1/2, 1/2).

In this problem, the question asks us for 3 parts
a) the predicted hourly pay rate for a cashier who doesn't have any experience.
In this problem, the scatterplot was reduced into a linear function modeled by the equation y=0.94x+7.86 where y is the pay in $ per hour and x is years of experience indicating pay is dependent on the independent factor of years of experience. 0 years when plugged into the equation yields this through substitution. 0.94(0)+7.86=7.86$ which is the y-intercept
b)this is simply substitution as one can plug in 7 as x 0.94(7)+7.86=14.44$ or appx. 14$
c) for this problem it asks us the predicted difference in the hourly pay rate however the equation y=0.94x+7.86 tells us for every x year pay goes up an average of 0.94$, therefore, the increase is 0.94$.
Overall, this problem challenges the student's understanding of linear equations and the meaning of x and y in relation to one another in a graph.
Which statement explains why the system of equations has no solution? y=−3x−5 and y=−3x+5
Answers
Explanation: The equations are parallel and will never intercept. Therefor they have no solution.

Answer:
33 units²
Step-by-step explanation:
Easiest way to approach this is to find the area of the rectangle, then subtract the area of the triangle.
Rectangle Area = length x width = 7 x 6 = 42
Area of triangle = 1/2bh = 1/2(6)(3) = 9
Area of the shaded figure = 42 - 9 = 33 units²

A photographer’s darkroom needs a new coat of black paint on all surfaces of the room, including the ceiling and the floor. The room is a cube with edge length 11
feet. How much surface area must be painted?
Answers
The surface area of a cube is given by the formula 6s^2, where s is the length of the edge. In this case, s = 11 feet, so the surface area of the cube is:
6s^2 = 6(11)^2 = 6(121) = 726 square feet
Since the room has six surfaces that need to be painted (four walls, one ceiling, and one floor), the total surface area that needs to be painted is:
6 x 726 = 4356 square feet
Therefore, the photographer's darkroom needs to have 4356 square feet of black paint applied to all of its surfaces.

Tameka surveys every fourth customer leaving two different self-service yogurt shops. She asks customers how much they spent on a single cup of yogurt. The results of her survey are shown in the box plots below. What is the difference in the median cost for a single cup of yogurt purchased at Yummy Yogurt and a single cup of yogurt purchased at Yo's Yogurt Shop? How do the interquartile ranges differ for the costs at the two yogurt shops? What can be inferred about the price per ounce at the yogurt shops based on the results of the survey?
Answers
What we can deduce from both box plots is that: Yummy's yoghurt shop has a higher average cost than Yo's Yoghurt shop.
How to Interpret the box plot?The box plot is a visual way of presenting a dataset where the rectangle is used to represent the quartiles. Box plots are useful as they show the skewness of a data set
The box plot shape will show if a statistical data set is normally distributed or skewed.
When the median is in the middle of the box, and the whiskers are about the same on both sides of the box, then the distribution is symmetric.
When the median is closer to the bottom of the box, and if the whisker is shorter on the lower end of the box, then the distribution is positively skewed (skewed right).
When the median is closer to the top of the box, and if the whisker is shorter on the upper end of the box, then the distribution is negatively skewed (skewed left).
Looking at both box plots, it is clear that:
Yummy's yoghurt and Yo's Yoghurt are skewed to the right. Thus, Yummy's yoghurt shop has a higher average cost than Yo's Yoghurt shop.
