Quadrilateral P'Q'R'S' is a dilation of the quadrilateral PQRS, with the origin as the center of dilation.
What is the rule used to create this dilation?

Answers

answer: the dilation is 0.5

step by step solution: life

The dilation scale factor of the quadrilateral is k = 1/2

What is Dilation?

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

The result of dilation is that the shapes and boundaries of objects in the input image are expanded or thickened. It is often used in conjunction with other morphological operations such as erosion, opening, and closing to manipulate and enhance images.

Given data ,

Let the scale factor of the dilation be represented as k

Now , the coordinates of the quadrilateral PQRS is

P ( -2 , 5 )

Now , the coordinates of the quadrilateral P'Q'R'S' is

P' ( -1 , 2.5 )

So , the dilation factor k is given by

k = -1 / -2

k = 1/2

Hence , the dilation is k = 1/2

Bill: How many books did you read this summer?
Lisa: Which book was first recommended to be read by the book club during the summer break?

Who wrote a statistical question and why?

Bill, because there will be variability in the responses collected
Lisa, because there can be only one answer to the question
Bill, because every student will give the same answer
Lisa, because there can be many answers to the question

Answers

Answer:

Bill, because there will be variability in the responses collected

Step-by-step explanation:

Bill is asking a statistical question, because the goal of the question is to gather data about the number of books consumed by each of the book club memebers, which could even then be formed into a data plot to review how many members of the book club fit into each number. The person who read the most amount of books would be the maximum number on the plot, and 1 would be the minimum

Mary reduced the size of a painting to a width of 3.3in. What is the new height if it was originally 58.8in. tall and 39.6in. wide? Round to the nearest tenth.

Answers

Answer: 4.9 inches

Explanation:
39.6 / 3.3 = 12 That means that the painting’s width was reduced to 12 times less than the original size. Now we need to apply that to the length.

58.8 / 12 = 4.9

The new height is 4.9 inches.


Optional:
If you want to check, compare the ratios of width/length in the original and new. If done correctly, both ratios should be equal when plugged into a calculator.

39.6/58.8 and 3.3/4.9
Both equal 0.67 so we can be sure that the answers are done correctly.

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. Write and solve an equation to find the answer. From midnight to 6:00 am, the temperature rose 8°C. At 6:00 am, the temperature was − 20 ° C. What was the temperature at midnight?

Answers

Answer: -28 degrees Celsius

Step-by-step explanation:

Equation: -20 = t + 8 or t = -20 + -8 (t represents the temperature at midnight).

Using the second equation given, add the two numbers together. Since adding a negative is the same as subtracting a positive, subtract 20 from 8 and make it negative. The answer is -28.

I don't understand this... please help :(

Answers

Answer:

Radius is the distance from the center of the circle to the edge (if you were to cut just a slice of pizza)

diameter is directly in the middle from one end to the other (if you were to cut the pizza in half)

this means that the diameter is DOUBLE the radius

circumference is the length of the outside of the circle (so the length of the pizza crust)

this one is tricky because to find circumference you need to do  [tex]2\pi r[/tex] (r is the value of the radius)

so for problem 1 the radius is 3 cm (the line is equivalent to if you were trying to cut out one slice of pizza)

the diameter is DOUBLE the radius, so if you were to cut the pizza in half all the way it would be 6 cm

and the circumference ([tex]2\pi r[/tex]) is 2 * pi * 3 cm

because it says to round pi to 3.14, the circumference would be 18.84

What is the shape of the distribution shown below?

Answers

Answer: its B they come from both sides

The shape of the graph indicates that the distribution is symmetrical. The correct answer is B

As we know that skewness is a measure of a distribution's asymmetry and can be positive (right-skewed), negative (left-skewed), or zero (symmetrical).

The center of the distribution is depicted in the graph. This signifies that the distribution's tail extends to the middle, and the majority of the data is concentrated on the graph's middle side.

Here, the majority of the data is between 0 and 50, and there are fewer data points between 50 and 100. This creates a long tail on the middle side of the graph, indicating that the distribution is symmetrical.

Therefore, the correct answer is B: The distribution is symmetrical.
