Best ResponseYou've already chosen the best response.1it's a right triangle so you can apply Pythagorean theorem \[a^2+b^2=c^2\]

Best ResponseYou've already chosen the best response.1btw its one of special triangle 5,4,? ;P

Best ResponseYou've already chosen the best response.1the first way is to use pythagorean theorem the 2nd way (really the first way) is to memorize some right triangle sides: 3,4, 5 and 5,12,13 are the sides of a right triangle. If you memorize these you will be faster.

Best ResponseYou've already chosen the best response.1and if you really want to get good, notice that a multiple (multiply each side by the same number) is also a right triangle for example if we multiply each side by 2: 6,8,10 is a right triangle check it: 6*6+8*8= 36+64= 100 and 100 is 10*10

Best ResponseYou've already chosen the best response.1btw forgot the tell you c is the longest leg of right triangle (hypotenuse )

phi

Best ResponseYou've already chosen the best response.1first, the leg is *always* shorter than the hypotenuse. so the number is less than 5 if you do not memorize 3,4,5 (which number is missing in your picture?) then you solve it this way x*x + 4*4= 5*5 x^2 +16= 25 add 16 to both sides x^2 +1616= 2516 simplify x^2 = 9 find the square root of 9

Best ResponseYou've already chosen the best response.0jose has 7 blue and 5 white shirts in one drawer in his dresser he is running late so whats the probability of pulling a white shirt randomly

Best ResponseYou've already chosen the best response.1probability is number of ways to "win" divided by the total number of choices

Best ResponseYou've already chosen the best response.0im thinking its 7:5 but sometimes i get it backwards

phi

Best ResponseYou've already chosen the best response.1probability is between 0 (no chance) to 1 (100% going to happen) so the fraction always has a smaller number up top and a bigger number in the bottom (unless it is 100% which would mean top and bottom are the same number)

phi

Best ResponseYou've already chosen the best response.1How many shirts does he have? how many are "winners" (i.e. white, the color we want) ?

phi

Best ResponseYou've already chosen the best response.1yes and that adds up to 12 now write the fraction: number of ways to win divided by the total number of shirts

phi

Best ResponseYou've already chosen the best response.1yes, though I would write it 5/12 the 5:12 typically means "odds" like in horse racing. Odds are more complicated then probabilty
