Under ideal circumstances, a certain type of bacteria can triple every 20 minutes. If a sample of 7 bacteria is allowed to grow in ideal circumstances, answer the following. (a) Find an equation for a model for the number of bacteria B after h hours have passed. --Select- (b) Estimate the number of bacteria present after 4 hours. bacteria (c) Estimate graphically when the number of bacteria will reach 1 million. (A graphing calculator is recommended. Round your answer to the nearest hundredth of an hour. Include units in your answer. More information.)
Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
