The low temperatures on january 1st in a city for 5 years are shown below..
2°f, -10°f, 7°f, 4°f, -13°f
what was the average low temperature on january 1st for the 5 years?
-2.5°f
-2°f
0.6°f
4°f

-2°F

Step-by-step explanation:

The average low temperature on January 1st is an arithmetic mean.

It is equal to the sum of all low temperatures on January 1st divided by the number of January 1st for 5 years.

Therefore, the average low temperature on January 1st

=

=

= -2 (°F)

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.
