<span>First of all in order to find the exact value by using a half angle identity we will do
cos(5π divided by 12)
=cos (5π divided by 6) divided by 2
= ± Under root[(1+cos (5π divided by 6) divided by 2]
Now we will consider + sign because 5π divided by 12 is in quadrant. where cos>0
so the solution is [(1- Under root 3 divided by 2) divided by 2]
We will ignore the negative sign
I hope it helped.</span>
Answer:
A) 0.1538
Step-by-step explanation:
4 members are going to be chosen:
M1 - M2 - M3 - M4
We have to find the probability that for each member, one without experience is chosen. There is no replacents.
Initially, we have 15 students, of which 10 have none experience. So the probability that M1 is chosen as a student with no experience is
.
Then, there are 14 students, of which 9 have no experience. So the probability that M2 is chosen as a student with no experience is
.
For the third member, there are 13 students, of which 8 have no experience. So the probability that M3 is chosen as a student with no experience is
.
For the last member, there are 12 students, of which 7 have no experience. So the probability that M4 is chosen as a student with no experience is
.
What is the probability that none of the members chosen for the team have any competition experience?
This is

The correct answer is:
A) 0.1538
I would help but I need more information help me help you
Answer:
If the line passes through the orgin
Step-by-step explanation:
We know the order of operations, right? PEMDAS
Parenthesis
Exponents
Multiplication
Division
Addition and
Subtraction.
So, by using the order of operation, it would come out to:
-24
But I don't see that as an answer choice... a typo maybe? :) Hope this helps anyways!
