question 107

Short Answer

Use the REGRESSION feature on a graphing calculator.
-A particular bacterium is found to have a doubling time of 20 minutes. If a laboratory culture begins with a
population of 300 of this bacteria and there is no change in the growth rate, how many bacteria will be present
in 55 minutes? Use six decimal places in the interim calculation for the growth rate.
