I am inclined to think that it is A. or B. Because they represent the highest probability, if it is not those it might be D.
This probably didn’t help, but if it did. I am glad (╹◡╹)
X-3=66
x=69
69+41+(y-9)=180
110+y-9=180
101+y=180
y=79
-3 < x < -8
There is no value of c that is greater than -3 AND less that -8
F(x) = 20000 (1-0.15) power x
So
f(x) = 20000 (0.85) power x
The independent variable is the variable that is being changed. In this statement, it would be water flowing flowing in the pool. The dependent variable is what is being changed so that would be the depth of the water.
There, I hope this helps! :)
