HEY...SORRY...THE ANSWER IS 320
math
288
geometry
steve-ur right.. we can place six points on each of it's veritices...nd if we put the other point on it's center,the maximum distance between the two closest points will be same as the length of it's side length...so the answer is 20.

P(X < 14.0) = P((x - 15.7) / 0.7) < (14.0 - 15.7) / 0.7) = P(Z < -2.43) = 0.0076 P(X < 18.0) = P((x - 15.7) / 0.7) < (18.0 - 15.7) / 0.7) = P(Z < 3.29) = 0.9995 or use calc by typing in normalcdf(-99,-2.43) and normalcdf(-99,3.29)you get the same probabilitie...
