Selena babysits on the weekends. The equation y = 12x represents the amount of money she earns. What is the constant of proportionality?
Answers
Answer: According to the question the constant would be 12
Step-by-step explanation: Its 12 because every hour she earns 12 dollars and as the y changes so will the amount of money she earns Ex: y=2 she earns 24 dollars.
Step by step- She is constantly earning 12 dollars per hour and that factor is never changing therefore it would be the constant of proportionality

The scatter plot shows the resale value of the same make and model car and the age of the car in years. Predict the price you would pay if you purchase one of these cars that is 9.5 years old.
Answers
Answer: $4000
Step-by-step explanation:
In the age of cars you go 9.5 and then go up till you reach a part of the line. In that, you can see that 9.5 goes up and reaches the line at $4000.
The predicted price you would pay if you purchase one of these cars that is 9.5 years old is 4000.
What is a scatter plot?A scatter plot is a graphical representation of bivariate data that uses dots to represent values for two different variables.
The data for each observation is represented by the position of the dot on the x-axis and y-axis.
The x-axis represents one variable and the y-axis represents the other variable.
Scatter plots are commonly used to observe relationships between variables, such as correlations or trends, and to identify outliers or patterns in the data.
We have,
To predict the price you would pay for a car that is 9.5 years old, you need to look at the scatter plot and find the point that corresponds to an age of 9.5 years.
Once you have identified that point, draw a vertical line from that point to the line of best fit (or draw the line of best fit if it's not already on the plot).
Next, draw a horizontal line from the point where the vertical line intersects the line of best fit to the y-axis.
This will give you an estimated price for a car that is 9.5 years old based on the data in the scatter plot.
Now,
We see that,
At 9.5 years, the vertical line and the horizontal line correspond to a resale value of 4000.
Thus,
The predicted price you would pay if you purchase one of these cars that is 9.5 years old is 4000.

Answer: The group which receives no physical therapy would best be described as the Control Group.
In an experimental study, the control group is a group of participants who do not receive the treatment being tested. They are used as a basis for comparison to evaluate the effectiveness of the treatment. In this case, the researchers are testing whether the new physical therapy reduces the recovery time for patients who underwent surgery for a torn ACL. The control group allows the researchers to compare the recovery time of patients who received no physical therapy to those who received either traditional or experimental physical therapy.

The number of cookies that were made at a bakery for each of seven days is shown:
108, 96, 96, 84, 108, 240, and 84
The best measure of center for this data set is the-
A: median because all of the values are close to one another in value
B: mean because all of the values are close to one another in value
C: median because 240 is much higher than the other numbers in the data set
D: mean because 240 is much higher than the other numbers in the data set
Answers
The data set is as follows: 108, 96, 96, 84, 108, 240, and 84.
The median represents the middle value when the data set is arranged in ascending or descending order. In this case, when we arrange the data in ascending order, we have: 84, 84, 96, 96, 108, 108, 240. The middle value is 96, which is the fourth value in the sorted data set.
The mean is calculated by summing up all the values and dividing by the total number of values. In this case, the sum of the values is 756 (108 + 96 + 96 + 84 + 108 + 240 + 84), and there are seven values. Therefore, the mean is 756/7 = 108.
Comparing the options:
A: median because all of the values are close to one another in value - This is not accurate as the values vary, and the median is not necessarily the best measure of center based on the values being close to one another.
B: mean because all of the values are close to one another in value - This is not accurate as the values are not all close to one another, and the mean is not necessarily the best measure of center based on the values being close to one another.
C: median because 240 is much higher than the other numbers in the data set - This is not accurate as the presence of a single high value does not automatically make the median the best measure of center.
D: mean because 240 is much higher than the other numbers in the data set - This is the most accurate option. The mean takes into account the magnitude of each value and is influenced by extreme values. The value 240 has a significant impact on the mean, making it a better measure of center in this case.
Therefore, the best measure of center for this data set is D: mean because 240 is much higher than the other numbers in the data set.
An elevator is being pulled up from the ground floor to the third floor by a cable. The cable is exerting 4500 newtons of force on the elevator. According to Newton's law of action-reaction, what is the gravitational force on the elevator and the people in it, in newtons, if the elevator is not accelerating?
Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value.
Answers
Answer:
The gravitational force on the elevator = 4500N
The given parameters are;
The force applied by the elevator, F = 4500 N
The acceleration of the elevator = Not accelerating
From Newton's third law of motion, the action of the cable force is equal to the reaction of the gravitational force on the elevator which is the weight, W and motion of the elevator as follows;
F = W + Mass of elevator × Acceleration of elevator
∴ F = W + Mass of elevator × 0 = W
F = 4500 N = W
The net force on the elevator is F - W = 0
The gravitational force on the elevator = W = 4500N.
Answer:
The gravitational force on the elevator = 4500N
The given parameters are;
The force applied by the elevator, F = 4500 N
The acceleration of the elevator = Not accelerating
From Newton's third law of motion, the action of the cable force is equal to the reaction of the gravitational force on the elevator which is the weight, W and motion of the elevator as follows;
F = W + Mass of elevator × Acceleration of elevator
∴ F = W + Mass of elevator × 0 = W
F = 4500 N = W
The net force on the elevator is F - W = 0
The gravitational force on the elevator = W = 4500N.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
A right rectangular prism has a height of 17.5 centimeters. The area of the base of the prism is 18 square centimeters. What is the volume, in cubic centimeters, of the right rectangular prism? (6.GM.2)
Answers
The volume of a right rectangular prism is given by the formula V = lwh, where l, w, and h represent the length, width, and height of the prism, respectively. Since the prism is right and rectangular, the length and width are perpendicular to each other.
We are given that the height of the prism is 17.5 centimeters and the area of the base is 18 square centimeters. Since the base is rectangular, we can find the length and width by dividing the area by one of the dimensions and multiplying by the other. Let's say the length is x and the width is y, then:
xy = 18 (area of base)
y = 18/x (solve for y)
Now, we can substitute the value of y in terms of x into the formula for the volume:
V = lwh = xyh = (18/x)(x)(17.5) = 315 cubic centimeters
Therefore, the volume of the right rectangular prism is 315 cubic centimeters.

x=157°
Step-by-step explanation:
opposite angles are equal so the angle opposite the 45° is also 45°
angles around a point add to 360°
so if we take away both the 45° we are left with the two other angles, one of them part of the triangle
360°-45°45°=270°
divide this by 2 to get the 2 angles
270°÷2=135°
angles in a triangle add to 180°
180°-22°-135°=23°
23° is the other angle in the triangle next to x
finally angles on a straight line add to 180°
180°-23°=157°
so x=157°
