Disposable income is the amount left after taxes have been paid and is one measure of health of the economy. The table gives the total disposable income for a country, in billions of dollars, for selected years from 2010 and projected to 2040. Complete parts (a) through (c) below. Year 2010 2015 2020 2025 2030 2035 2040 Income ($ billions) 10.328 11.149 12.992 14.283 15.342 17.118 19.835 a. Can these data be fitted exactly by a linear model? OA. Yes. The first differences are constant for uniform inputs. OB. Yes. Each first difference is double the previous first difference for uniform inputs. C. No. The first differences are not constant for uniform inputs. OD. No. The data do not include every year between 2010 and 2040. n b. Find a linear model that models the data, where x is the number of years after 2000 and y is the total disposable income in billions of da y=0x+0 (Type integers or decimals rounded to three decimal places as needed.)
