Use the following information for questions 1 through 4.

A student measured data on how many marbles fit in various sized rings. Some of their data is shown in the graph below.

0.5

What is the pattern shown by this data?


0.5

Using the graph or the mathematical model, determine the number of marbles that you would expect to fit in a ring with an 8-cm diameter.

0.5

Using the mathematical model, calculate the number of marbles that you would expect to fit in a 16-cm diameter ring.

0.5

How much confidence do you have in your prediction for #3 above? Use the confidence rubric below to help you.

Use the information below for questions 5-8.

Students measured travel times for a toy car for different speeds. Their data is shown in the graph below.

0.5

What is the pattern shown in the graph?

0.5

Use the graph or the mathematical model to predict the travel time if the car has a speed of 35 meters/second?

0.5

Use the mathematical model to calculate the travel time if the speed is 2 meters/second.

0.5

Does the pattern for the travel time vs. speed make sense to you? Explain your reasoning.
