Your daily commute to work requires that you cross railroad tracks. At this particular railroad crossing the trains tend to be long and slow, So, getting stopped by a train will likely make you late for work. You start recording data to determine the likelihood of arriving at the tracks while a train is there. The data contain the day number and whether a train was present, or not, for 200 consecutive days in which you drove to work in the data set, the column Train shows a series of 0s and 1s. In that column a 0 indicates there was no train present and a 1 indicates that a train was present. The column Aggregate Train represents the cumulative number of times a train was present. Consider the first 10 days of data. For this time period, what proportion of days had a train present? (Round to four decimal places as needed)

A bicycle racer sprints near the end of a race to clinch a victory. The racer has an initial velocity of 10.95 m / s and accelerates at the rate of 0.55 m / s^2 for 5.5 s to accomplish this. What is his final velocity, in meters per second, after this period of acceleration? The racer continues at this velocity to the finish line. If he was 325 m from the finish line when he started to accelerate, how much less time did it take him to finish than if he had not accelerated? One other racer was 6.5 m ahead when the winner started to accelerate, but was too tired to speed up and traveled at 11.6 m / s until the finish line. If the winner continues to cycle at the same speed after crossing the finish line (to celebrate his victory), how far ahead of the loser will the winner be, in meters, when the loser finishes?

The following table shows the wind chill C(T, w) (in °F) as a function of the air temperature T (in °F) and the wind speed w (in miles per hour) according to the current National Weather Service model. 5 10 15 20 25 30 35 ------------------------ 40 36 34 32 30 29 28 28 35 31 27 25 24 23 22 21 30 25 21 19 17 16 15 14 T 19 15 13 11 9 8 7 25 13 9 6 4 3 1 0 15 7 3 0 -2 -4 -5 -7 10 1 -4 -7 -9 -11-12-14 There are three ways to estimate a partial derivative from a table of values, the forward difference quotient (for example, fx(a, b) approximates (f(a+h, b)-f(a, b))/h with h>0), the backward difference quotient (for example, fx(a, b) approximates (f(a, b)-f(a-h, b))/h with h>0), and the symmetric difference quotient (for example, fz(a, b) approximates (f(a+h, b)-f(a-h, b))/(2 h) with h>0). The symmetric difference quotient is just the average of the forward and backward difference quotients. The forward difference quotient approximation to CT(15,25) is °F / °F. The backward difference quotient approximation to CT(15,25) is °F / °F. The symmetric difference quotient approximation to CT(15,25) is °F / °F. The forward difference quotient approximation to Cw(15,25) is -0.2 °F / mph. The backward difference quotient approximation to Cw(15,25) is -0.4 °F / mph. The symmetric difference quotient approximation to Cw(15,25) is °F / mph. The National Weather Service has also provided an empirical formula for approximating the wind chill. It states that C(T, w) approximates 35.74+0.6215 T+w^(0.10)(-35.75+0.4275 T) Based on this formula, CT(15,25) approximates °F / °F and Cw(15,25) approximates °F / mph.
