Question
The amount of plastics in our waste stream increased from 390,000 tons in 1960 to 35,680,000 tons in 2018. (Plastics: Material - Specific Data, EPA).
The amount of plastics in our waste stream increased from 390,000 tons in 1960 to 35,680,000 tons in 2018. (Plastics: Material - Specific Data, EPA). In 1980 20,000 tons of plastic were recycled, representing 0.3% of the plastic waste. By 2018 this had increased, but still remained below 10%. Plastic is proving very difficult to dispose of. To determine if the recycling response has increased as the amount of plastic waste has increased, researchers compared the percent recycled to the amount generated from 2000 to 2018. Data for five years are below. Plastic Generated (Millions of Tons) Amount Recycled 25.6 5.8% 29.4 31.4 6.1% 8.0% 34.5 9.0% 35.4 8.7% a) Plot the points. (2.5 pts, I axes) Does the data appear to be linearly related? (0.5 pt) b). Find the Regression Equation and add the regression line to the graph. (3 pts) c) Predict the amount recycled for a year with 27 million tons of waste plastic. Show the substitution. (2 pts) (1 pts) d) What percent of the variation in the amount recycled is explained by the regression line?
