Geometry
if the pen has dimensions x by y, with x along the barn, then x+2y = 115 the area a is thus a = xy = (115-2y)y this is a parabola, with maximum at y=115/4 so, x = 115/2 so, a pen 115/4 by 115/2 gives the maximum area

Yes, it would be unusal for the mean of a sample of 3 to be 115 or more because there is only a 4.18% chance for this to happen. P(X >= 115) = P(X >= (115 - 100) / sqrt(15^2 / 3)) = P(X >= 1.732050808) = 0.0418

Well, \$115 is exactly one SD below the mean, so that's handy. A useful guideline is that, moving left to right, over 2SD covers the first 2%; 2-to-1 SD is another 14%, bringing you up to 16%, and 1-to-0 SD covers another 33%, bringing you to the mean at 50% (not quite, because...

aside from the ambiguity caused by a paucity of parentheses, #1 looks ok #2 (-3)^2 = 9, not -9 but that's ok, since you dropped it in the next step anyway.Other than that, it's virtually incomprehnsible. Add some parens so it's clear what is wanted. I can guarantee that 115/3-...
