Starting from the entrance of her school, alyssa walked 400 feet due north, then 300 feet due east, and ended up at the entrance of a running track. miki walked directly from the entrance of the school to the entrance of the running track. how many more feet did alyssa walk than miki?

Alyssa walked 200 ft more than Miki.

Step-by-step explanation:

According to the Pythagorean theorem formula if we square the a(400) and b(300) and add them both we would get 250,000. From then you square root it to 500. So Miki walked 500ft and Alyssa walked 700ft (400+300). Subtract 500 from 700 and you would get 200ft.

the expected value of the random variable : 0, 1 and 2
