Answer:
v = -5, t = -13. , d = -12
Step-by-step explanation:
29) 3v - 9v = 30
Simplifying gives us -6v = 30. Then dividing both sides by -6 reaches our answer of v = -5.
30)12t - 8t = -52
Simplifying gives us 4t = -52. We can divide both sides by 4 to reach a conclusion that t = -13.
31) -8d - 5d + 7d = 72
Simplifying gives us -6d = 72. We can then divide both sides by -6. In doing so, we can achieve our answer that d = -12.
If nCk represents the number of ways k parts can be chosen from a pool of n, the probability of interest is the complement of the probability of selecting all good parts.
1 - (167C3)/(170C3) = 42,085/804,440 ≈ 0.0523
_____
nCk = n!/(k!(n-k)!)
-2 is the correct answer.
