Use the data shown in the table that shows the number of bacteria present after a certain number of hours. Replace each y-value in the table with its logarithm. log y. Find the equation of the regression line for the transformed data. Then construct a scatterplot of (x, log y) and sketch the regression line with it. What do you notice? Number of hours, x: 1 2 3 4 5 6 7 Number of bacteria, y: 325 533 965 1623...

Suppose ?(?) represents the number of bacteria in a dish t hours after the start of a lab experiment. a) Interpret the meaning of ?(20) = 100 100 is the average rate of change in the number of bacteria after 20 hours. 100 is the rate of change in the number of bacteria after 20 hours. After 20 hours, there are 100 bacteria in the dish. 100 is the total change in the number of bacteria between the first hour...

The initial size of a culture of bacteria is 1500. After one hour the bacteria count is 6000. A.) Find a function n(t) = n0ert that models the population after t hours (round your r value to five decimal places.) n(t)= B.) Find the population after 1.5 hours. (round answer to nearest whole number.) n(1.5)= C.) After how many hours will the number of bacteria reach 10,000? (round your answer to one decimal place.)
