The table lists the speeds of the fastest roller coasters in North America and Asia. Roller Coaster Speeds in North America (miles/hour)Roller Coaster Speeds in Asia (miles/hour) 128 149.1 120 106.9 100 95 93 83 92 80.8 90 80.3 85 78.3 82 71.5 80 69.6 77 68.4 The difference of the means of the two data sets is . The mean absolute deviation of the roller coaster speeds in North America is . The mean absolute deviation of the roller coaster speeds in Asia is .

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

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.  

so what is the problem what are they asking you to solve

the answer is y = 11.54

hope this : )
