MHB Display information on a normal curve

AI Thread Summary
To display the average hospital stay for patients undergoing abdominal surgery on a normal curve, the mean is set at 6.4 days with a standard deviation of 1.4 days. This creates a bell-shaped curve centered around the mean, indicating the distribution of patient stays. The sample size of 15 patients provides a basis for estimating the population parameters. Visual representation can be achieved using graphing software or statistical tools that plot the normal distribution. Properly illustrating this data helps in understanding patient stay patterns and planning resources effectively.

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
