Rather than carrying out IBP several times, let's establish a more general result. Let

One round of IBP, setting


gives


This is called a power-reduction formula. We could try solving for
explicitly, but no need.
is small enough to just expand
as much as we need to.





Finally,

so we end up with


and the antiderivative is

2/7 as a fraction rounds to 0.3
0.3 * 3 = 0.9
3 x 2/7 is less than 3
Answer: 90 degrees acute
Step-by-step explanation: math
1st draw: 5/26
2nd draw 4/25
probability of 2 vowels = 5/26* 4/25
rearrange to make the math easier
= 5/25* 4/26
= 1/5 * 2/13
=2/65
Slope intercept form Y=0.5x+6
