Quizplus · Accepted Answer

To find the mean number of bacteria in an 8-milliliter sample, we can use the formula: mean = (concentration) x (volume)

In this case, the concentration is 6 per milliliter and the volume is 8 milliliters.

Mean = (6 per milliliter) x (8 milliliters) = 48 bacteria

Therefore, the mean number of bacteria in an 8-milliliter sample is 48, making choice (B) the correct answer.
