You already got the first two questions right: the group with the highest number of people unemployed / unemployment rate is the one with the highest bar in the respective histogram.
The two graph are related in this sense: take the first age group as reference. We know that 700 people from 16 to 19 are unemployed, and that those people represent 14% of the population, then we know that the 14% of the population between 16 and 19 is 700.
We can deduce that, if x is the number of people between 16 and 19, we have

So, by the relation between the two graphs, we can deduce the total population for each age group.
The answer is D, 40%. I got it by knowing that 3 and 4 were the success numbers and that 0,1, and 2 were unsuccessful and that numbers 3 and 4 are less than half, so I went with 40% and it was right. Good luck apex! Finish strong!
yo sup??
the sum of trails taken should be less than 25 miles
Black bear=B
Eagle Ridge=E
Doe Run=D
(btw names sound cool XD)
we will now try different combinations
B+E=7 1/2 ++ 10 1/4 which is clearly less than 25
B+D=7 1/2 + 8 3/4 which also less than 25
E+D=10 1/4 + 8 3/4 which is also less than 25
B+D+E=7 1/2 + 10 1/4 + 8 3/4 which is greater than 25
Therefore only the 1st,2nd and 3rd case are possible
Hope this helps.
Oh yeah, now give me branliest.
