How many times greater is the MAD for Class A than for Class B? What does
this show about the variability of the
data sets? Explain.

If you make you answer for clear i can answer it : )

Google it that might work

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
