The value of a truck decreases exponentially since its purchase. The two points on the graph shows the truck's initial value and its value a decade afterward. 50 (0,40,000) 40 30 value in thousands of dollars 20 (1.24,000) 10 0.5 decades since purchase A) Express the car's value, in dollars, as a function of time d, in decades, since purchase. B) Write an expression to represent the car's value 4 years after purchase.​

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
