If a correlation coefficient is 0.80, then:
a. the explanatory variable is usually less than the response variable.
b. the explanatory variable is usually more than the response variable.
c. below-average values of the explanatory variable are more often associated with below-average values of the response variable.
d. below-average values of the explanatory variable are more often associated with above-average values of the response variable.
e. none of the statements are correct.

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00

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.
