Well, one way to eliminate the possible options, is to look for the point of the starting mass, which is 8 milligrams. This eliminates graphs A and B, this leaves graphs C and D, knowing the mass is decreasing and not increasing, the correct graph would be D.
We can check this, by taking the mass of the substance and dividing it by 2, the remaining mass of the substance would be 4 mg.
For a compression, a has to be less than one, and for a shift to the right, h has to be negative
the only one to meet both criteria is D
Experimental probability is doing a test and basing probability on that.
Like if you roll a dice 100 times and 6 comes up 21 times, the
experimental probability is 21%.

Hope this helped!

2a+3b=82
a+b=38
These are the two equations you need to solve for a and b
