The situation would be an example of replication because the company is trying to find out and replicate results that would occur in the general population.
Answer = V (2,1)
Because:
The equation of the circle is
(x+1)² + (y+3)² = 25
(2+1)² + (1+3)² = 25
3² + 4² = 25
9 + 16 = 25
25 = 25
To write and equation we call y=oil and x=vinager, so:

To find the constant k we can use the point in the picture (vinager, oil) = (x, y) = (1, 1.5), so:

So, the equation is:

Now, the meaning of the point (1, 1.5) is for 1 amount of vinager you need 1.5 amount of oil.
3(x+3)= 8-2x
3x +9 = 8 - 2x
3x + 1 =-2x
1 = -5x
x = -1/5
no
