F(x) = x^2 -2x + 4
f(-2) = (-2)^2 -2(-2) +4
f(-2) = 4 + 4 + 4
f(-2) = 12
12 is your answer
Hope this helps
If x is inversely proportional to y, then:
x=k/y.
When y=2, x=3.
3=k/2, therefore k=6.
So, x=k/y is in fact x=6/y.
When x=9:
9=6/y
9y=6
y=6/9=2/3.
Solution: We are given:

We have to find the amount of water that represents the top 97.5%.
We need to find the z value corresponding to probability to 0.975. Using the standard normal table, we have:

Now using the z score formula, we have:





Therefore, 129.4 ounces amount of water represents the top 97.5%
