Step-by-step explanation:
Give me more points, and I will ;)
1/4 * x + 1/4 * 4
(the * are multiplication signs)
Remember
the deritivive of f(x)/g(x)=(f'(x)g(x)-g'(x)f(x))/((g(x))^2)
deritivive of lnx is 1/x
derivitive of t^2=2t
so

=

=
9/20 because if you count the red and blue out of the 20, theres 9. So you have a 9/20 chance it will hit red or blue.
