On a school trip to a theme park, four busses each carry 175 students. 45% of the students are bringing their own lunch. 3 7 of the students are buying lunch when they get to the theme park. The teachers are worried that some students have not made plans for lunch. Find how many students have not made plans for lunch.

348

Step-by-step explanation:

175(kids per bus) times 4(# of buses) =700

45% of 700 =315

so if you subtract 315 from 700 you get 385

then you subtract the kids who are buying lunch when they get there

385-37=348

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.
