Some Problems
hashbrown2009   3
N 10 minutes ago by HacheB2031
1. If x squared minus (x squared times pi)/4 equals 3+ 3 root 3 -2pi, solve for x.
2. You're playing a game where you need to roll at least N to win. You can either roll 2 6-sided fair dice or a 12-sided fair die. For what value of n between 1 and 12, inclusive, is the probability of winning equal no matter which dice you choose?
3. Define the polynomial P(x)=(x^3)+1. Find the sum of the coefficients of P(P(P(x))).
4. Jerry chooses 2 positive integers x and y that yield a product of 6^5, or 7776. He then computes the value of n, which is the GCD of (a,b). How many possible values of n can Jerry get?

Provide solutions to answers


Also how hard are these problems: AMC8, AMC10, MathCounts, or AMC12?

Easy Counting?

Lucien randomly picks two distinct numbers at the same time from the following group of numbers: $\frac{1}{8}, \frac{1}{4},\frac{1}{2},1,2,4,8$. If the product of the 2 numbers is also a member of this group, how many selections can be done?

Actually, there are only 7 numbers, otherwise, the solution is correct. so 7C2=21.
That means 21-4=17
