Final answer:
To predict the bacteria population after 15 hours, one must use exponential growth calculations which involve finding the growth rate from the initial growth data and applying it to an exponential growth formula. The question does not provide enough information for a direct, two-line answer.
Step-by-step explanation:
The subject of this question is Mathematics, specifically dealing with exponential growth in a biological context. The bacteria growth described is an example of an exponential model which can be used to predict future population sizes.
After 3 hours, the bacteria population grew from 6,000 to 6,600, an increase of 600 bacteria. To predict the bacteria population after 15 hours, we need to find the growth rate and apply it to the initial amount. If we assume the growth continues at a constant rate, applying exponential growth calculations will provide an estimate for the total number of bacteria after 15 hours. We can set up the problem in terms of an exponential growth equation:
N(t) = N_0 × e^(rt),
where N(t) is the final population size, N_0 is the initial population size, e is the base of the natural logarithm (approximately 2.71828), r is the growth rate, and t is time. With the provided population sizes at 0 and 3 hours, we can approximate r and then use it to calculate the expected population at 15 hours. To provide a additional information is needed or a different method must be used that does not rely on the growth rate, as it has not been directly provided.
