In a study of plant safety, it was found that the time it took for machine operators to react to a warning light was normally distributed with a mean 1 second and standard deviation 0.3 second. suppose a warning light visible to 4 operators goes on. what is the probability that the average (mean) reaction time of the 4 operators exceeds 1.25 seconds?

Graph a triangle (xyz) and reflect it over the line y=x to create triangle xāyāzā. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point xā to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then yā with the reflecting line? how do you know?
