Assuming that you have 50 subjects that you want to randomly assign to two different groups of 25, explain how you would use a random number table to do it.

its c or d   take a lucky guess my dude

answer: x=60

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
