A manufacturer is discussing upgrading a model of one of their tvs. There is a 55% chance that it will produce a profit of $250,000, a 25% chance it will produce a profit of $150,000, and a 25% chance it will lose $200,000. Based on this information, should the company upgrade the tv? Provide the expected value.

just sum

10 + 10 = 20

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.
