The track coach wanted to know who he should give the most valuable player award to at the last track meet.  The runners were normally distributed with a mean of 8 and a standard deviation of 2.  Tim ran the race in 6.5 minutes.  The long jump was normally distributed with a mean of 6ft  and a standard deviation of 1.5ft, and Elena had a jump of 8ft.  Who should the award go to, and explain why or show work to support your claim.

Elena wins, she has a z-score of +1.33 compared to Tim's z-score of -0.75, Tim would need to be at a z-score lower than -1.33 to be the better track person in this case.

Farmer Fred had a square field with sides of 525 feet. He wants to build a fence down one diagonal of the field to separate it into two equal parts. How many feet of fencing will he need to purchase? Use special right triangles to show your solution, he must buy fencing in integer amounts of feet, so give an answer that will give him enough fencing to the nearest whole number.

He needs 743 feet of fencing.
