Honolulu Legacy Goes the eBay Way
For this year's NSPE Annual Convention, July 8-13, NSPE and the Hawaii Society
of Professional Engineers have chosen Habitat for Humanity in Honolulu as the
beneficiary of the convention's legacy project. Using money raised through an
eBay charity auction--the goal is $20,000--the legacy will enable PEs to build a
house for one family in the host city.
Up for bids are two rounds of golf at Oahu's Hawaii Prince Golf Club; dinner for
two at any Marriott; golf at Ko'olau Golf Club; or a one-night stay at any
Marriott or Renaissance Hotel in U.S., Canada, Mexico, Central and South
America, and the Caribbean. Check out
the Legacy page on eBay for more details.

MATHCOUNTS PROBLEM OF THE WEEK
Can you solve this MATHCOUNTS problem? The answer will appear in next week's
edition of the Friday Update!
Women Finish First (Men Still Run Faster)
For the first time in the 108-year history of the Boston Marathon, the women
started the marathon 29 minutes before the men. The first place woman finished
with a time of 2 hours, 24 minutes, 27 seconds. The first place man’s time was 2
hours, 10 minutes, 37 seconds. How much time elapsed between the winning woman
crossing the finish line and the winning man?
--------------------------------------------------------------------------------
The first U.S. man across the finish line was the 13th male finisher and ran the
marathon in 2 hours, 25 minutes, 45 seconds. If the first 13 male finishers’
times form an arithmetic sequence, how long would it have taken the 10th place
male to finish the race?
--------------------------------------------------------------------------------
Though not the record-breaking heat of 96 degrees in 1976, the weather
conditions were much tougher than the usual 57-degree average temperature for
April in Boston. Due to the 85-degree heat, officials had 80 pounds of ice at
each of the 26 stops along the route. What percent of a ton did the total amount
of this ice weigh?
Answer to last week's problem:
First, we can figure out how many possible pairings there are for the final two
competitors. This is a “16 choose 2” problem, which is (16!)/[(2!)(14!)] = 120
ways. Now we need to see how many pairings exist for each of the four shows.
They will all still be “x choose 2” situations. For the Simpsons kids, there are
"3 choose 2" = 3 combinations; for the Seinfeld stars, there are "4 choose 2" =
6 combinations; for the ESPN anchors, there are "6 choose 2" = 15 combinations;
and for the Dragonball Z characters, there are "3 choose 2" = 3 combinations.
This is a total of 3 + 6 + 15 + 3 = 27 combinations of two people that are both
from the same show. The probability is then 27/120 = 9/40.
--------------------------------------------------------------------------------
Since the mean of the four scores was 15, we know that the four scores totaled
15 × 4 = 60. The scores of Lisa and Nelson account for 29 of these points,
leaving 31 points to distribute between Ralph and Bart. Since they were both
higher than 10 and not prime, we can start checking pairs of numbers… 12 & 19
(No), 14 & 17 (No), 15 & 16 (Yes!) This pair satisfies all of the conditions.
(You can also check to see that this is the only combination that works.) Since
Bart’s score was the lower than Ralph’s, his score was 15 points.
--------------------------------------------------------------------------------
We know that #9 was answered correctly, so that doesn’t factor in. We know that
#2 being answered correctly has a probability of 1/2 and the probability of #4
being answered correctly is 2/3. Therefore, the probability of all three of
these events occurring is 1 × 1/2 × 2/3 = 1/3.
