Answer:
120
Step-by-step explanation:
From 20, choose 3:
₂₀C₃ = 120
Here we use combinations instead of permutations because the order doesn't matter.
Domain means the input of x-values
example: (4,3) (2,1)

Domain Domain
(<span>72 + 79 + 73 + 81 + 70</span>)/5 = 375/5 = 75
<span> A. 75</span>
Ratio in the first sample = 250/1000 = 1/4 = 0.25
ratio in the second sample = 750/2000 = 0.375
hence ,<span> there is a greater proportion of smokers in the second city than in the first.
