Final answer:
The number of bacteria in the petri dish after 150 minutes, assuming a doubling time of 30 minutes, can be expressed as 25 or 32. None of the provided multiple-choice answers match this calculation, suggesting additional context is required.
Step-by-step explanation:
To express how many bacteria are in the petri dish after 150 minutes, we need to consider the doubling time of the bacteria. If we assume that the doubling time is consistent with previous examples provided, such as doubling every 30 minutes, we can calculate the number of times the bacteria population has doubled in 150 minutes.
150 minutes divided by the doubling time of 30 minutes is 5 doublings. Thus, the number of bacteria after 150 minutes can be expressed as a power of the number of doublings. Since the bacteria double each time, we use 2 raised to the power of the number of doublings, which is 25.
The calculation is expressed as 25, which equals 32. However, since none of the provided answer choices (A. 224, B. 210, C. 410, D. 220) exactly match this result, there may be additional information from the student's coursework needed to provide the exact answer per their study materials.
