Answer:
Step-by-step explanation:
The base case in the recursive function are:
The recursive case is equal to:
So replace 
for 
:
In the new expression 
is a base case so you don't have to worry for that part, but 
is still the recursive case so evaluate again in
and 
are define as base cases so you replace for it's numbers:
Now return to and replace for the new values:
So the final answer is 20

Answer:
No solution
Step-by-step explanation:

sub tract 3x on both sides and poof
we get 8 =8

Answer:
Chicago marathon runners
Step-by-step explanation:
Due to the strict qualifying time, the runners of the Boston marathon are going to very prepared, and quite close in their times. Since they are going to be close, the standard deviation is expected to be small.
Otherwise, in the Chicago marathon, anyone can run. This means that along with the professional runners, who are going to be very prepared, other unprepared runners will compete, and they are going to take a long time to complete the race, adding variation to the finishing times. The standard deviation is the square root of the variance, so since the variance for the Chicago marathon will be higher, the standard deviation also will
