Hello,
Looking at the data, you should go with the second and fourth results.
On the second one, Dr. Appiah's M.A.D. is only 9.7 which is less than Dr. Singh's M.A.D. of 14.1
On the fourth one, Dr. Cantwell and Dr. Singh both have a M.A.D. that is only 0.1 from 14, so their ages vary by about the same amount.
Best of luck,
MrEQ
One question, are they congruent figures?
Written as an inequality- x+18<28
15/3 = 5 hope this helped!
The answer is: [B]: "arithmetic" .
