The orbital movements of planets in our solar system can be modeled by elliptical equations. Discuss the shapes of the path of the Moon around the Earth and the Earth around the Sun.

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
