Question
The following table shows the approximate amount of trash produced in an industrialized country from 1980 to 2000. Let x represent the year after 1980 (1980 is year 0) and y represent the amount of trash (millions of tons).
Year | Million Tons |
1980 | 154 |
1990 | 204 |
2000 | 218 |
(a) Draw the graph for this data.
(b) Find the equation of the regression line for the data. (Round your answers to one decimal place.)
y = x +
(c) Use the equation to predict the amount of trash y that will be produced in 2010 and 2015. (Round your answers to one decimal place.)
(b) Find the equation of the regression line for the data. (Round your answers to one decimal place.)
y = x +
(c) Use the equation to predict the amount of trash y that will be produced in 2010 and 2015. (Round your answers to one decimal place.)
in 2010 | million tons | |
in 2015 | million tons |
