On a coordinate grid, point p is at (5, 2) and point r is at (−3, −4). points q and s are a reflection of both points across the x-axis. what are the coordinates of q and s?

q(−5, 2), s(3, −4)
q(−5, −2), s(3, 4)
q(5, −2), s(−3, 4)
q(−5, 2), s(−3, 4)

Name the quadrilaterals that have four equal sides.

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
