The difference of twice a number and 10 is less than 22

2(n-10)≤ 28 or n ≤ 24

2x-10≤22

Step-by-step explanation:

2x≤22+10=32

x≤16

probability for j is 1/4

while

a is 1/6

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.
