This would be 2c^3 Answer
Answer:
She has a total of 300 action figures.
Step-by-step explanation:
19 : 100 = 57 : x
x = 100/19 * 57
x = 300
686 barrels left. If I'm not mistaken this should just be simple subtraction
Using order of operations, the answer is 569.
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
