Answer:
Option: A is the correct answer.
          The number of weeds is decreasing by a multiplicative rate.
Step-by-step explanation:
Clear;y from the scatter plot we could observe that with the increasing value of one variable the other variable is decreasing.
Hence, The number of weeds is decreasing.
Also as we could see that the line of best fit is a curve and not a line Hence, the number of weeds are not decreasing by a additive rate  ( since the rate or a slope of a line is constant) it is decreasing by a multiplicative rate.
<em>Based on the graph of a regression model:</em>
<em>Option: A is correct.</em>

Step-by-step explanation:
I don't know if the first set of numbers is all in one set, but I'll do my best to give you an answer.
Really all you need to do is use PEMDAS for the first question.
(Parentheses, exponents, multiply, divide, add, subtract. In that order)

Then to simplify that fraction next to it, notice that 0.018 is 3x 0.06.
that's a 3:1 ratio, so it ends up simplifying to this:

Lastly, to solve the division of that fraction. If you divide by a fraction, you multiply whatever it's dividing by its inverse.
So...
