Question

Mini-Project #1: Linear Models The United States is the largest waste producer in the world with most of the waste being dumped into the ground. As with most states, Indiana's landfills are filling at an alarming rate Listed are the tons of waste generated for the years 1990-1994. These numbers include solic waste and material that may be recycled. (Source: Monroe County Solid Waste Management, Bloomington, Indiana. Funded in part by the National Science Foundation and Indiana University 1995) in Tons of waste Year 1990 132.956 1991 135,686 1992 136,102 1992 1993 137,793 139,417 1994 1. Create a scatterplot that shows the tons of waste generated in Monroe County, Indiana for the years displayed in the table. You may use your graphing calculator (and take a picture) or use Excel (and paste a copy) to create the scatterplot of this data. Your graph must be labeled and included as part of this document when submitted 2. Use the first and last points (x 1990 and x-1994) to find the equation of a line that would well model these data. Give the slope-intercept form of the line. Vzaytb 3. Write a sentence to interpret the meaning of the slope in the context of this problem. 4. Using the line from problem 1, predict the number of tons of wste for the years 1995, 1997 and 1999. Please show your work 5. In 1994, 46,736 tons of the waste was recycled. If this rate remains the same, how many tons of waste will be recycled in 1995?
