In responding to a survey question on a sensitive topic (such as "have you ever tried marijuana? "), many people prefer not to respond in the affirmative. suppose that 80% of the population have not tried marijuana and all of those individuals will truthfully answer no to your question. the remaining 20% of the population have tried marijuana and 70% of those individuals will lie. derive the probability distribution of y, the number of people you would need to question in order to obtain a single affirmative response.

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores
