There are 10 letters in the set {a, b, c, d, e, f, g, h, i, j} which is the pool of letters to choose from when making these three letter codes.
We have 10 choices for slot 1
Then 9 choices for slot 2. This is because we can't reuse the choice for slot 1
Then 8 choices for slot 3
Overall, there are 10*9*8 = 90*8 = 720 different permutations
Answer: 720
Note: you can use the nPr permutation formula with n = 10 and r = 3 to get the same answer
→Answer:
A. strong positive
→Step-by-step explanation:
Well looking at the following scatterplot we can tell it is not negative only positive.
So we can cross out B. and C.
Looking at the dots and how close they are to creating a line we can decuct answer choice A. Because it is a strong positive.
For question 3. A
4. A
5. B

Answer:
ML = 7.5
Step-by-step explanation:
The parallel lines divide the transversals proportionally.
ML/LK = JH/HG
ML/10 = 6/8
ML = 10(6/8) = 7.5
The length of ML is 7.5.
__
We don't need to solve for x. If ML = x-2, then x=9.5.
