Solve the problem.The dropout rates of students at State University (rates per 1000 students) are shown in the table for various years. Let r be the dropout rate (number of dropouts per 1000 students) at t years since 2000.
a. What is the r-intercept of the model? What does it mean in this situation?b. Use the linear model to predict when the dropout rate will be 8 per 1000 studentsc. What is the t-intercept of the model? What does it mean in this situation?d. Predict the dropout rate in 2012. Explain.
What will be an ideal response?
a. (0, 39); the dropout rate in 2000 was 39 dropouts per 1000 students
b. 2008; answers may vary
c. (10, 0); in 2010 the dropout rate will be 0
d. -9 dropouts per 1000 students; model breakdown; answers may vary
