Answer:
The value is 
Step-by-step explanation:
From the question we are told that

given that y(0) = 0
We have that

=> 
This means that

We also given that
![y[\frac{\pi}{6} ] = 5](https://tex.z-dn.net/?f=y%5B%5Cfrac%7B%5Cpi%7D%7B6%7D%20%5D%20%3D%20%205)
So

=> 
Hence

Answer:
x = 20
ABC = 85
BCA = 81
CAB = 14
Step-by-step explanation:
I answered your other question, so basically just read the explanation there cuz I'm too lazy to write it again :P
Add all the chips to find the total amount.
7 + 9 + 3 + 6 = 25 chips
Since there are 6 blue chips (6/25), that's the probability of just getting once.
When you pick a blue chip and it doesn't get replaced, then that means there is one fewer blue chip and one fewer from the total amount.
5/24
Multiply both probabilities.
6/25 * 5/24 = 30/600
Simplify.
30/600 → 1/20
Therefore, the answer is B
Best of Luck!
