Use the value of the linear correlation coefficient r to find the coefficient of determination and the percentage of the total variation that can be explained by the linear relationship between the two variables. 0.767 1. What is the value of the coefficient of determination?2. What is the percentage of the total variation that can be explained by the linear relationship between the twovariables?

1. r² = 0.588

2. 59% of the variation of the dependant variable can be explained by this linear regression model.

Step-by-step explanation:

We have a regression model that has a linear correlation coefficient between the two variables with value r = 0.767.

The coefficient of determiniation r² will have a value of:

The percentage of the total variation that can be explained by the linear relationship between the two variables is given by the value of the coefficient of determiniation r².

So we can conclude that 59% of the variation of the dependant variable can be explained by this linear regression model.

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.
