Could you qualify for the AIME?
Introduction:

"This is a quiz similar to the American Invitational Math Exam (AIME), a difficult test given to qualified HS students every March. Every answer is an integer from 0 to 999 inclusive. A score of 3 out of 5 would be great."





--------------------------------------------------------------------------------
Question 1:

Consider the set of numbers S = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. You take every distinct two-element subset of S and write down the number that is larger. For example, if you take the subset 4, 6, you would write down the number 6 because it is larger than 4. What is the sum of all of the numbers that you write down?

Answer: ……(A number)


--------------------------------------------------------------------------------
Question 2:

What is the sum of all integers, n, 1 < n < 100, that satisfy the condition that 13 is a factor of (n^2 + 27n + 7)?

Answer:……….. (A number)


--------------------------------------------------------------------------------
Question 3:

An ellipse on the xy-plane has foci at (-41, 23) and (115, 42). The ellipse is tangent to the x-axis. What is the length of the major axis of the ellipse?

Answer :………. (A number)


--------------------------------------------------------------------------------
Question 4:

Suppose we are playing a board game with the following rules:

1. The board has 5 spaces on it.

2. Your playing piece starts out on space number 1.

3. Each move consists of moving the piece to a randomly chosen space other than the one which you currently occupy (for example, if you are on space number 2, you randomly move to either space 1, 3, 4, or 5, with each space having equal chance of being selected, but you cannot stay on space number 2).

4. You win if, after seven moves, you are back on space 1.



The probability of winning this game is p. Find 4096p.

Answer: ……….. (A number)


--------------------------------------------------------------------------------
Question 5:

Suppose log.4a (40*sqrt(3)) = log.3a (45)



(Log.m (n) denotes log base m of n. sqrt(x) denotes the square root of x.)



Find a^3 (a^3 denotes "a cubed.")

Answer: ………… (A number)
