Consider the following triangle: 72 1/2 32 1/2 2×16 1/3 Part A: Find the perimeter of the triangle.
72 1/2 + 32 1/2 + 32 1/3
72 1/2 + 32 1/2 + 2×16 1/3
104 1/2 + 2×16 1/3

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

the answer is:

mean: 6

mad: 2.14
