Answer:
The answer is 20,358,520
Step-by-step explanation:
Selecting 6 numbers from a collection of 52 numbers regardless of order involves a combination.
Note: if regards was taken into order of selection, this would be a permutation.
Hence, the different 6 number selections out of 52 is
52C6 = 52! / [6!*(52-6)!]
= 52!/(6!*46!)
= 20,358,520
1. 12*100 - 12*5
You would use the distributive property to get this equation (it is equivalent to the original one)
2. Um... There's no actual story for this problem; sorry I can't solve this problem
Answer:
174 in²
Step-by-step explanation:
(A1)= 9(5)= 45 in²
(A2)= 3(5)=15 in²
(A3)= 3(5)=15 in²
(A4)= 9(3)= 27 in²
(A5)= 9(5)= 45 in²
(A6)= 9(3)= 27 in²
(totalA)= 45+15+15+27+45+27= 174 in²
