Simplify the following polynomial expression: (5x2 – 9x + 2) + (-3x2 + 2x + 7) + (2x2 + 3) (22 – 5)
4x4 – 522 – 7x - 6
4x4 – 5x2 + 7x + 6
4x4 – 9x2 – 7x + 24
4x4 - 9x2 – 7x – 24

What is the length of the segment joining the points at (4,5) and (6,-2) round to the nearest tenth if necessary

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
