AI Thread Summary
Brent International School's basketball team currently has a winning percentage of 48% after winning 12 out of 25 games. To achieve a winning percentage of at least 60%, they would need to win 89 consecutive games. Winning 10 games in a row would raise their percentage to approximately 50%, while winning 15 games would bring it to about 52%. If they win 100 games consecutively, their winning percentage would be 100%, but it is impossible to achieve a 100% winning rate retrospectively. Understanding percentages is crucial for calculating these outcomes effectively.

In an inter school basketball league, the team from Brent International School has won 12 out of 25 games, a winning percentage of 48%. We have seen that they need to win 89 games consecutively to raise their percentage to at least 60% . What will be their winning percentage if they win;
a. 10 games in a row?
b. 15? 20? 30? 50? 100 games?
c. Can they reach a 100% winning rate?

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...

Thread 'Six Pencil Puzzle'

Is it possible to arrange six pencils such that each one touches the other five? If so, how? This is an adaption of a Martin Gardner puzzle only I changed it from cigarettes to pencils and left out the clues because PF folks don’t need clues. From the book “My Best Mathematical and Logic Puzzles”. Dover, 1994.

Thread 'Imaginary Pythagoras'

Thread 'Imaginary Pythagoras'

I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
