Answer:
1 / 362880
Step-by-step explanation:
There are 9 possible names that could be first.
After that, there are 8 possible names that could be second.
After that, there are 7 possible names that could be third.
So on and so forth.
So the number of permutations is:
9×8×7×6×... = 9! = 362880
The probability of randomly selecting the one order used in the spelling bee is therefore:
P = 1 / 362880
9.4 - 6 = 3.4
12.8 - 9.4 = 3.4
16.2 -12.8 = 3.4
hence the difference between the terms is common and = 3.4

answer is 2
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>Find b first:</u>
- b = 3/x + 3/y
- b = (3x + 3y)/xy
<u>Find 1/b:</u>
- 1/b = 1 : (3x + 3y)/xy
- 1/b = xy / (3x + 3y)
