The combination expression that demonstrates how the 20 is calculated using the combination pattern is 6C3
<h3>Permutation and Combination</h3>
While combination has to do with selection, permutation has to do with arrangement.
According to the combination rule
nCr = n!/(n-r)!r!
The expression that gives the result of 20 is expressed below;
6C3 = 6!/(6-3)!3!
6C3 = 6!/3!3!
6C3 = 6!/6*6
6C3 = 720/36
6C3 =20
Hence the combination expression that demonstrates how the 20 is calculated using the combination pattern is 6C3

For this case we have the following system of two equations with two unknowns:
Adding both equations we have to eliminate the variable "x":
Adding common terms, keeping in mind that different signs are subtracted and the sign of the major is placed:
Answer:
Option A
Answer:
45 copies per minute
Look at drawing for an explanation
Mes ∠AKG = mes ∠AKD + mes ∠ DKG
133° = mes ∠ AKD + 87°
133° - 87° = mes ∠AKD
∠AKD = 46°
The answer is 3 because percentage is out of 100. therefore 10 is 10 percent of 100, etc
