so I really need help. you have to set fractions equal to each other and try and find out how many dont have sweaters. out answer isn't supposed to be a fraction, it's supposed to be a whole number, I hope that makes sense. lol, thank you :)

114 prefer sweaters and 138 prefer jackets

Step-by-step explanation:

(19/23+19)×252=114 prefer sweaters

(23/19+23)×252=138 refer jackets

answer: about 22.67

step-by-step explanation:

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.
