Computer Science Canada Math Question...Bits Rewarded

 Author: Archi [ Mon Jul 28, 2003 11:43 pm ] Post subject: Math Question...Bits Rewarded 45 bits to the one who gets this question correct. The problem is as follows: ax+by/m=d Where, when a=40 & b=35 d=52 a=46, b=40, d=63 a=54, b=43, d=75 a=62, b=48, d=88 a=70, b=55, d=105 a=78, b=64, d=125 a=86, b=75, d=144 a=94, b=88, d=171 a=102, b=103, d=201 Find x,y,m. Note: x,y,m must be constant throughout the entire solution.

 Author: Archi [ Tue Jul 29, 2003 4:19 pm ] Post subject: hmm... Okey...well try this: I have 9 weapons...I have designated a certian % chance to hit for each weapon. What I need though, is a formula which will work for each weapon and will take into account the players accuracy, and also the hit chance of the weapon. Here are the number with the acc being that at the lowest lvl possible to equip the weapon. Weap 1: a=40 & b=35 d=74% Weap 3: a=46, b=40, d=77% Weap 3: a=54, b=43, d=80% Weap 4: a=62, b=48, d=83% Weap 5: a=70, b=55, d=86% Weap 6: a=78, b=64, d=89% Weap 7: a=86, b=75, d=92% Weap 8: a=94, b=88, d=95% Weap 9: a=102, b=103, d=98% This is for my hit/miss system where I will randomly pick a number between either 1-(a+b) or 1-100 depending on which has a valid solution. The d value is what percent I want the player to hit. So for weapon 1, I want him to hit roughly 74% of the time. So the answer has to be greater than 74% of the numbers.

Evidence: since y and m remain constant, make constant z=y/m equation is now ax+bz=d the first two equations read 1) 40x+35z=53 2) 46x+40z=63 mult 1) by 1.15 46x+40.25z=59.8 Subtract new equation from 2) to get 0x-0.25z=3.2 -0.25z=3.2 z=-12.8 Substituting this into 1) 40x+35(-12.8)=52 40x-448=52 40x=500 x=12.5 These value in the third equation d=54(12.5)+43(-12.8)=675-550.4=124.6 d is supposed to be 75. Therefore, no solution.
