The ration is 4 cups water:1 cup vinegar so c cups water:12 cups vinegar 4 water/1 vinegar =c water/12 vinegar cross multiply so 12 times 1 and 4 times c so you get 12/4c divide both sides by 4 and you get 3 c=3

Answer:
the probability when the IQ is lower than 136 is 0.9641
Step-by-step explanation:
Given that
The mean is 100
The standard deviation is 20
We need to find out the probability when the IQ is lower than 136
So,
z value equivalent to 136 = (136 - 100) ÷ 20 = 1.8
Now
p (z < 1.8) = 0.9641
hence, the probability when the IQ is lower than 136 is 0.9641
