Lian's truck has a 25 gallon tank and uses 0.05 gallon of gas for every mile driven. When creating a table for the function y=−0.05x+25, Lian argues that he can only use positive rational numbers for the input. Is Lian correct? Justify your answer.

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
