So, we are dealing with function notation.
F(x) can be thought of as Y= if it's easier.
So f(4) is what is the output value if X = 4. So we just plug 4 into the function wherever we see x.
I think there are some words omitted in your question, but i would answer it based on the given data.
The data set has 200 participant with 14 as its mean and with the deviation of 1. Then we could say that 50 per cent is of the participants has the hemoglobin count ranging from 13.0 to 13.9 and another 50 per cent ranging from 14.1 to 15.0.
1 chair = X
8 chairs = 8X
1 table = Y
8X - Y is the more amount you paid for chairs
D.
if you divide the measures of the name brand television, and then multiply those answers by 2, you'll get the size of the generic television.
(12÷3)×2=8
(24÷3)×2=16
