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

Since the density is 1.00 g/mL, that means we can use 1.0 mL = 1.0 g, I remember that 1 mg/L = 1 ppm So 0.115 g/4.55 L = 0.02527 g/L or that x 1000 = 25.27 mg/L or 25.3 ppm. Your way: 0.115 g/4550 g + (.115 x 10^-6) = 0.115 g/4550 g + (negligible) =. 2.527 x 10^-5 g/1.0 g. ...

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
