Exponential Regression The table below shows the population of a fictional California Gold Rush Town named Lehi in the years after its peak population in 1880. Year 1880 Population 9300 1890 3151 1900 1754 1910 937 1920 331 1930 122 For the purpose of this problem, let P represent the population of Lehi t years after 1880 (t=0 represents 1880). The new table is: t 0 10 20 30 40 50 P(t) 9300 3151 1754 937 331 122 Use your calculator to determine the exponential regression equation that models the set of data above. Round the "a" value to two decimals, and round the "b" value to three decimals. Use the indicated variables and proper function notation. P() Based on the your regression model, what is the percent decrease per year? Find P(55). Round your answer to the nearest whole number. P(55) = Interpret your answer by completing the following sentence. Be sure to use units in your answer. after 1880 was about The population of Leht How long did it take for the population of Leht to reach 490 people? Round your answer to the nearest whole number. P(t) = 490 when t = Interpret your answer by completing the following sentence. Be sure to use units in your answer. In after 1880, the population of Leht was about How long did it take for the population of Lehi to drop by half? Round your answer to the nearest whole number. P(t) has halved when t =
