If there are 500 mg of medicine in 5 ml of liquid, we need to set up a proportion to find out how much liquid medication has 125 mg of medicine in it. Set up the proportion as follows:
.
Cross multiply to get 500x = 625. Divide by 500 to get that you need 1.25 ml of liquid if your dose is 125 mg of medicine.
The best choice from the ones viewable in your picture is B) 1.
With that being said, 1 is used to indicate a perfect fit, which there is not one for this plot.
However, 0 would not be correct either, as 0 implies no correlation. We can see from the graph that there is a correlation.
-0.95 would not work either, as the line appears to trend upward; a negative correlation coefficient indicates it trends down.
It shouldn’t the whole number is 2/33 you don’t multiples anything
//You need to factorise the two quadratics and divide where possible
x^2 + 3x + 2 = (x+2)(x+1)
x^2 - 4 = (x+2)(x-2)
y = (x+2)(x+1)/(x+2)(x-2)
y = (x+1)/(x-2)
95 because if you do the math you’ll get the answer
