Compute the table for the distribution function for values
A normally distributed random variable X has the expectation X = -15 and standard deviation 10. Compute the table for the distribution function for values from near Pr(X) = 0 in increments of 10 and plot the graph of the distribution function.

In 2010, the men's record for the 26.22 miles Boston Marathon was 2 hours 5 minutes and 52 seconds. What was the average speed of the runner in units of m/s?
What is the angle the total electric force on the charge at x = +16 cm, y = 0 cm makes when measured from the positive x direction, counter-clockwise? Answer in degrees.
How much charge, in micro-coulombs, was exchanged? Use the absolute value of the charge exchanged so the answer is positive.
Three charges are placed on the y axis. One charge of -2.4 micro-Coulombs is placed at y = 0, another charge of +1.7 micro-Coulombs is placed at y = -0.2 meters, and another unknown charge is placed at y = +0.57 meters.
Suppose you are trying to measure the rate of (total) decay events per second R from a certain radioactive source using a detector hooked up to a counter.
