The graph shows the distance y, in miles, of a moving train from a station over a certain period of time, x, in hours: a graph titled distance vs time is shown with time in hours labeled on x-axis and distance from station in miles labeled on y-axis. the scale on the x-axis shows the numbers 1, 2, 3, 4, 5, 6, 7, and the scale on the y-axis shows the numbers 0, 45, 90, 135, 180, 225, 270, 315, 360. the graph shows a straight line joining the ordered pairs 0, 90, and 1, 135, and 2, 180, and 3, 225, and 4,270. what is the speed (in miles per hour) of the train and why? 45 miles per hour, because speed is the rate of change of distance 90 miles per hour, because speed is the initial value of the function 135 miles per hour, because speed is the distance traveled in unit time 270 miles per hour, because speed is the distance traveled in a certain time@prestonrobotics

Assume that there is a 11% rate of disk drive failure in a year. a. if all your computer data is stored on a hard disk drive with a copy stored on a second hard disk drive, what is the probability that during a year, you can avoid catastrophe with at least one working drive? b. if copies of all your computer data are stored on four independent hard disk drives, what is the probability that during a year, you can avoid catastrophe with at least one working drive?
