The following question came off the Mensa Puzzle Calendar for 2007.

"The square of the first number plus the second number equals 7. And the square of the second number plus the first number equals 11."

There's an obvious trivial solution, but there are also three other real solutions. I'm most interested in the 3 other solutions.

Answers must be provided in radical form, *not* as decimal approximations. Are you up to the challenge?

I roll a die twice.
E is the event that both rolls are even.
F is the event that the first roll is a four. (The elements of F are (4,1), (4,2), (4,3), etc.)
G is the event that the sum of the numbers on the dice is 7.
Which two events are mutually exclusive?
Pick one:
E and F
E and G
G and F
all of them?

When submitting an answer in the form of a fraction, use a forward slash (/) to separate the numerator and denominator. For example, one half would be written as 1/2.

I'm writing a SQL query which calculates the average daily water usage for a utility company.

Usage reads come to us in the following format:

ReadBegin (start date of meter reading)
ReadEnd (end date of meter reading)
Volume (in Liters)

The meter reads have a ReadBegin and ReadEnd typically crossing month boundaries, for example, 3/31/2007 and 4/13/2007. Most months there is only a single read for the month, but occasionally there are two.

My question, say you have these reads in a given month:

3/1/2007 - 3/31/2007, average daily usage 100.10 L
3/31/2007 - 4/13/2007, average daily usage 39.4 L

What would be the proper way to factor in the average daily usage for 3/31, since here there are essentially two meter reads (and therefore two ranges used to calculate averages) used?

I was thinking that for March 1 - 30, I would use 100.10 (the ADU for the first read), and for March 31 I would use the average of the two averages, 100.10 + 39.4 / 2.
