Answer:
It takes 7.37 hours for the size of the sample to double.
Step-by-step explanation:
Continuous exponential growth model:
The continuous exponential growth model for populations is given by:
In which P(0) is the initial population and r is the growth rate parameter, as a decimal.
Growth rate parameter of 9.4% per hour.
This means that
So
How many hours does it take for the size of the sample to double?
This is t for which P(t) = 2P(0). So
It takes 7.37 hours for the size of the sample to double.
