Please actually answer and don't just take the points.

Which lines are perpendicular to the line y – 1 = 1/3(x+2)? Check all that apply.

Please explain why, I would appreciate it

-y + 2 = –3(x – 4)

-y − 5 = 3(x + 11)

-y = -3x – 5/3

-y = 1/3x – 2

-3x + y = 7

Ineed with number 17 i don’t get it at alll

Arrange these numbers from least to greatest 3/5 5/7 2/9

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
