An experiment designed to measure the growth of bacteria began at 2:00 P. M. and ended at 8:00 P. M. on the same day. The number of bacteria is given by the function N, where N(t) = 1000 . 3^2t/3 and t represents the number of hours that have elapsed since the experiment began. Required:
How many more bacteria were there at the end of the experiment than at the beginning of the experiment?

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e.g. 98.7654). x f(x) 0 1 2 3
