Colonial Population The table shows the colonial population estimates of the American colonies for each decade from 1700 through 1780.
Let
(a) Use the regression feature of a graphing utility to find an exponential model for the data.
(b) Use the regression feature of the graphing utility to find a quadratic model for the data.
(c) Use the graphing utility to plot the data and the models from parts (a) and (b) in the same viewing window.
(d) Which model is a better fit for the data? Would you use this model to predict the population of the United States in 2020? Explain your reasoning.

- There were 426 books sold in one week. The number of biology books sold was 5 times that of the number of psychology books. How many books each were sold?arrow_forwardPopulation decreases 5% each year. Starts with a starting population of 3705. Find that population after 5 years.arrow_forwardsolve using substitution -2x-3y=-15 -3x+9y=12arrow_forward
