The answer to the question mentioned above is "the mean" such as the whole sentence will become "The horizontal value at which the highest point of a variable's normal curve is also the MEAN of the variable". This is the answer.
9x9=81 so there is 9 on 2 sides, which is 18 when it gets added together. DONT FORGET ABOUT THE OTHER 2 SIDES!! you have four sides of the square so 9x4=36. I believe the answer is actually 36
