Alex gets an A in ECE 153 and flies home determined to convert as many people as she can into probability lovers, or probabilistic. Every person Alex meets gets a "lecture" about the beauty and utility of the subject and with probability half gets infected with Alex’s love for the topic, and becomes a probabilistic, and with probability half does not. Each person’s response is independent of all others. Let Xn be the random number of probabilists among the first n people Alex meets. For example, X1 is 0 or 1, each with probability 1/2, while X2 is 0, 1, or 2, etc

linearly: 8560 bacteria

exponentially: approximately 75233 bacteria

step-by-step explanation:

assuming it is not exponential (we would have some really complicated logarithms), let's say it is linear. then, after 5 hours, it increased by 1200 bacteria, so every hour it increases by 240 bacteria. this means that after 19 hours, we get 19 * 240 + 4000 bacteria or 3800 + 760 + 4000 = 7800 + 760 = 8560 bacteria.

because it says round your answer, i will do this exponentially (with a calculator, of course). first, we need to find how much it multiplies by every hour, by taking the 5th root of 52/40 or 13/10. this is approximately 0.167. we still need to add 1 to this, because we are multiplying by that number, not adding that amount of the number. now, we just calculate 4000 * (1.167)^19. use a calculator to get approximately 75232.6, or 75233.
