Textbook Problem

The table gives the population of the United States, in millions, for the years 1900- 2010. Use a graphing calculator with exponential regression capability to model the US population since 1900. Use the model to estimate the population in 1925 and to predict the population in the year 2020.

To determine

**To find:** The population in the year 2020.

Explanation

**Calculation:**

Consider the given table as follows,

Year | Population |

0 | 76 |

10 | 92 |

20 | 106 |

30 | 123 |

40 | 131 |

50 | 150 |

60 | 179 |

70 | 203 |

80 | 227 |

90 | 250 |

100 | 281 |

110 | 310 |

Use the online graphing calculator, obtain the exponential regression model as

The population in the year 2020 as follows,

An initial year population is 76 million.

The general form of the population is
