Round your answer to the nearest hundredth. Selected Answer: 39.0124 Question 9 5 out of 5 points Based on your linear model, in what year would you expect the discarded plastic to reach 50 million tons? Write your answer as the four-digit year. Selected Answer: 2042 Question 4 What is the initial value of your model? Round your answer to four decimal places. X Selected Answer: 0.39 Question 5 The initial value has no meaning in context of this problem, because the amount of plastic was not negative in 1960. Selected Answer: True Question 6 What is the slope of the model of best fit? Round your answer to four decimal places.
