Problem 9-10 Graph the following data as a scatterplot. Remember to enter each pair as a point in (x,y) form.

Problem 9-10a Does the graph show either a positive or negative association or neither?

Problem 9-10b Does there appear to be an association between height and spelling ability?

Problem 9-10c Does greater height cause better spelling ability?

Problem 9-10d What other factors could create the association you see? Answer this question on the discussion board in schoology.

Problem 9-11a Josue called his father to say he was almost home. He had traveled 61.5 miles, which was 3/4 of the way home. Which of the following equations could be used to solve for how far it was for Josue to get home?

d represents the distance to Josue home

Problem 9-11b Josue called his father to say he was almost home. He had traveled 61.5 miles, which was 3/4 of the way home. Use your equation from the previous question to solve for the distrance Josue will travel to get home.

Problem 9-13a Determine if the graph is a function or not a function. (Remember the vertical line test)

Problem 9-13b Determine if the graph is a function or not a function. (Remember the vertical line test)

Problem 9-13c Determine if the graph is a function or not a function. (Remember the vertical line test)

Problem 9-13d Determine if the graph is a function or not a function. (Remember the vertical line test)

Problem 9-13e Determine if the graph is a function or not a function. (Remember the vertical line test)

Problem 9-13f Determine if the graph is a function or not a function. (Remember the vertical line test)

Problem 9-12 Ryan and Janelle are each driving from a different location to meet. When they each stopped for lunch at 12 noon, they called each other on their cell phones. Ryan had traveled 245 miles in 3 1/2 hours. Janelle had driven 260 miles in 4 hours.

If Ryan and Janelle were originally 910 miles apart when they had started driving that morning, at what time will they meet?
