Answer:
yes :
use the following formula :
a^2 +b^2 = c^2
now apply it to the problem :
5^2+12^2=13^2
do the exponent :
25 + 144 =169
now add
169 =169
if they are equal , then it is a right triangle .
This is true. The closer to the mean that a value is, the more likely it is to occur.
In this case, two and three standard deviations away are both fairly unlikely, however, two is still more likely to occur than three.
