Answer:
1) If the order doesn't matter, there are 36 possible outcomes.
2) If the order does matter, there are 181,440 possible outcomes.
Step-by-step explanation:
1) In the case when the order doesn't matter , we have to calculate a combination of 7 screws in 9 holes.
We use the formula for combinations:
being r: the number of screws and n: the number of holes.
2) When the order does matter, the possible outcomes are called permutations. We have permutations of 7 screws in 9 holes.
We use the formula for permutations:
Completely different...
.15*.15*.15*500
500(.15^3)=1.6875
500(.45)=225
Distribute the negative.
- 8 - 2a =
Factor out -2
-2 ( 4 + a)
The function represents a linear relation so I assume the answer is B neither
