Unit activity: making inferences and conclusions...part D: based on your observations, what actually happens to the meaning of simple properties and the standard error of the proportion as you increase the number of samples... part E: according to the central limit theorem, what type of distribution will these sample proportions give you? Part F: calculate the 68%, 95%, and 99.7% confidence intervals for the sample proportions.

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.  

0,0

step-by-step explanation:

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
