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:
53
Step-by-step explanation:
Sol'n
Let the remaining angle of a triangle be x.
x+71+56=180 (Sum of angles of a triangle is 180°)
or, x+127=180
or, x=180-127
.:, x=53°
.:, The measure of third angle is 53°
They are both behind the decimal, they are both a decimal, they can both be turned into a fraction, and they both have a six
Answer:
∠A = 70°
Step-by-step explanation:
I'm... guessing this is what you mean? It would've been helpful if you'd provided pictures.
Since all parallelograms consist of two pairs of vertically opposite angles, ∠A and ∠C are equivalent.
Which means that 2x + 50 = 3x + 40.
In which you solve the equation.
2x + 50 = 3x + 40
-2x -2x
50 = x + 40
-40 -40
x = 10
Now, to find ∠A, substitute x into the equation:
∠A = 2x + 50
x = 10
∠A = 20 + 50
∠A = 70
Hence, ∠A = 70°
This would be 25%.
Reason:
If there are 12 total cupcakes and 3 out of them are chocolate. Then 3/12 cupcakes are chocolate. Simply this fraction to 1/4 -> 1/4 = 25% = .25 etc
