If they are not equal, then the 2's supplementary
The total combination will be, 45195 if the selecting dance troupe with 6 girls and 7 boys out of 20 girls and 15 boys who auditioned.
<h3>What is permutation and combination?</h3>
A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have:
Selecting a dance troupe with 6 girls and 7 boys out of 20 girls and 15 boys who auditioned.
It is a combination problem:
Selecting 6 girls out of 20 = C (20, 6)
Selecting 7 boys out of 15 = C (15, 7)
Total combination = C (20, 6) + C (15, 7)
= 38760 + 6435
= 45195
Thus, the total combination will be, 45195 if the selecting dance troupe with 6 girls and 7 boys out of 20 girls and 15 boys who auditioned.

Answer:
In mathematics, a set is closed under an operation if performing that operation on members of the set always produces a member of that set. For example, the positive integers are closed under addition, but not under subtraction: 1 − 2 is not a positive integer even though both 1 and 2 are positive integers.

Step-by-step explanation:
Multiple each sales total by .1 and then add 150. If they equal then it works, if they don't then it doesn't. No other way I can think of to explain this.
We know that there are 100 cm in 1 m. We can convert 0.75 m to cm by multiplying by 100 to give us:

Therefore the path before the addition is 75 cm wide.
Mr. Kassel added 20 cm of blocks on each side of the path, meaning that the added width is actually 40 cm total (20 on each side, and there are 2 sides).
So we need to add 40 cm to the original 75 cm:

So now we have the width of the path in cm, the question asks for the width in meters. We can do this by dividing the width in cm by 100 to get the width in meters:

Now we know that
the new width of the path is 1.15 m.
