A right rectangular prism has a surface area of 214 cm2. Its height is 7 cm, and its length is 5 cm. Which equation can be used to find the prism's width, w, in
centimeters?
A 35 + 12w = 214
B 70 + 14w = 214
C 35 + 10w = 214
D 70 + 24w = 214

1. a right triangle is graphed on a coordinate plane. find the length of the hypotenuse. round your answer to the nearest tenth. 2. use the angle relationship in the figure below to solve for the value of x. assume that lines a and b are parallel and line c is a transversal.

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
