Question 26 (1 point) The Holmes and Rahe Stress scale was created by physicians. Their hypothesis was that: When a person experiences combined life events where the stress equals 300,000 points or more, then the person's chances of experiencing a suppression of their immune system increases greatly. This means on top of dealing with all of the stress, they will likely get sick as well. Stress is a normal part of life and the more a person experiences stress, and the higher the score, then the stronger that person will get. Feeding cows beer and massaging them increase the chances that the meat will be good and fatty!

On the Richter scale, the magnitude, M, of an earthquake is given by $$M = \frac{3}{2}log\frac{E}{E_0}$$, where E is the energy released by the earthquake measured in joules, and $$E_0$$ is the energy released by a very small reference earthquake. Part A $$E_0$$ has been standardized to $$10^{4.4}$$ joules. The earthquake in Haiti in 2010 released $$2.0 \cdot 10^{15}$$ joules. What was its magnitude on the Richter scale?
