The scatter plot below represents the weight of a box of cookies based on the number of cookies in the box. A best-fit line shows the relationship.

Answer:

a. true

b. false

c. false

d. false

e. true

Step-by-step explanation:

a is true because the graph is measuring the weight of the box based on the number of cookies in it, and the box has weight even without cookies in it.

b is false because the slope of the line is 1/2, and each cookie weighs 1/4 oz.

c is false because there is an association between the number of cookies and the weight of the box.

d is false because that is the weight of one cookie, and doesn't take into account the weight of the box by itself.

e is true because the graph shows that at 13 cookies, the box weighs around 3.75 ounces.

An equation was created for the line of best fit from actual enrollment data. It was used to predict the dance studio enrollment values shown in the table:


Enrollment Month
January February March April May June
Actual 500 400 550 550 750 400
Predicted 410 450 650 650 600 450
Residual 90 −50 −100 −100 150 −50


Analyze the data. Determine whether the equation that produced the predicted values represents a good line of best fit.
No, the equation is not a good fit because the sum of the residuals is a large number.
No, the equation is not a good fit because the residuals are all far from zero.
Yes, the equation is a good fit because the residuals are not all far from zero.
Yes, the equation is a good fit because the sum of the residuals is a small number.

One afternoon, Dillon and 3 friends visit the zoo. They split the cost of parking the car evenly. Then each person buys a ticket to enter the zoo. By the end of the afternoon, each person has also purchased 2 bottles of water.
• Let p represent the parking cost.
• Let t represent the ticket cost.
• Let w represent the cost of a bottle of water.
Use the dropdowns to complete the statements.



(A) One way to express the total cost is to find the cost per person for a ticket and water. Then multiply this expression by
Choose...
and add
Choose...
.


(B) The expression for total cost described in part A is
Choose...

The two dot plots below compare the forearm lengths of two groups of schoolchildren:

Based on the visual inspection of the dot plots, which group appears to have the longer average forearm length?

A. Group A, because a child in the group has the least forearm length of 10 inches.

B. Group A, because four children have a forearm length longer than 12 inches.

C. Group B, because no child in the group has a forearm length longer than 12 inches.

D. Group B, because five children in the group have the least forearm length of 10 inches.
