LOL, idk if this is right, but it is how i think it should be solved
Answer:
A. Height is input, Weight is output
Step-by-step explanation:
We are given the statement,
"Weight is a function of height".
As we know,
<em>In a function of the form
, the input variable is 'x' and the output variable is 'y'.</em>
If we write the given statement in the form
, we get,

This means that the input variable is 'Height' and the output variable is 'Weight'.
Hence, option A is correct.
The estimate would be 1200.
We will set up a proportion for this. 10 out of 60 of the sample were tagged, so that is the first ratio. The 200 that were tagged would be in the numerator of the second ratio (10 was the portion tagged, and 200 is the portion tagged, so they both go on top). We do not know the total number so we use a variable:
10/60 = x/200
Cross multiply:
10*x = 60*200
10x = 12000
Divide both sides by 10:
10x/10 = 12000/10
x = 1200
