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
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
First you will divide I-2xI on both sides that should look like this:
-2x/-2 = 10/-2
when you divide it your -2‘s should cancel out and you should be left with
-x=10/-2
when You divide 10/-2 you should get -5
10/-2= -5
your answer should look like this then
-x=-5
-5 is just one of your answers the other is 5
To get rid of the negative on the -X you have to didvide it by both sides
-x/-x=-5/-x
your answer should be
X= 5
your final answers are
-5 or 5

The solution expressed in interval form is:
Answer:
x = 5
Step-by-step explanation:
It is given that the angle below is a right angle, meaning that it is 90 degrees.
So, 8x and 50 must both add up to 90 degrees.
Let's make an equation that we can solve using this information.
8x + 50 = 90
8x = 40
x = 5
