The Optional vs. The Necessary
Consider this table of data relating to the number of plastic surgery procedures and the number of cardiac surgeries each year:
Number each year | 1997 | 2003 |
Plastic surgeries | 721,000 | 1,380,000 |
Cardiac surgeries |
3,230,000 | 3,550,000 |
Assuming growth in each row is linear, what are the two expected values for years 2010 and 2025?
- Number of plastic surgery procedures?
- Number of cardiac surgeries?
Assuming growth in each row is exponential, what are the two expected values for years 2010 and 2025?
- Number of plastic surgery procedures?
- Number of cardiac surgeries?
