The probability of a train arriving on time and leaving on time is 0.8. the probability of the same train arriving on time is 0.84. the probability of of this train leaving on time is 0.86. given the train arrived on time, what is the probability it will leave on time?

Find the solution of system of equation y= x-4 y=4x+2

Logan wants to know how many skateboards have defective parts. he inspects 20,000 skateboards and keeps track of the number of defects per board. use his probability distribution table to find the expected value for defects on a skateboard.

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
