N(N ∩ S ∩ K) = 10
n(ξ) = 250
n(S ∪ K) = 15 - 10 = 5
n(N ∪ S) = 20 - 10 = 10
n(N ∪ K) = 30 - 10 = 20
n(S) = 50 - 10 - 5 - 10 = 25
n(K) = 55 - 20 - 5 - 10 = 20
n(N) = 100 - 10 - 20 - 10 = 60
n(N ∪ S ∪ K) = 10 + 5 + 10 + 20 + 25 + 20 + 60 = 150
Therefore, n(N ∪ S ∪ K)' = 250 - 150 = 100
Therefore, 100 million people do not read any of the three papers.
Answer:
If you meant average as in mean, then it would be 2000.
Step-by-step explanation:
1000=1000
2300=2000
2600=3000
You add them all up and you get 6000. Then you would divide by 3. In the end , you should get 2000.
1000+2000+3000=6000
------------------------------------- = 2000

Answer:
No, you can't.
Step-by-step explanation:
1,500*.9= 1350
Therefore, the tv would still be $350 too much.
Percent formula : is/of = %/100
is = 48
of = 160
% = x
48/160 = x/100
cross multiply
160x = 4800
x = 4800/160
x = 30......so 48 is 30% of 160
