World Population One projection of the world population by the United Nations (a low-projection scenario) is given in the table below. The data can be modeled by y = −0.36x2 + 38.52x + 5822.86 million people, where x is the number of years after 1990. In what year after 1990 does this model predict the world population will first reach 6,702,000,000?
Year | Projected Population (millions) |
1995 | 5666 |
2000 | 6028 |
2025 | 7275 |
2050 | 7343 |
2075 | 6402 |
2100 | 5153 |
2125 | 4074 |
