What two clues does the author provide that lead you to conclude that he is making an ethical appeal?

5.4%

explanation:

their acceptance rate is 5% percent and the graduation rate is 98%

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
