12+12-12+12_24=?
Assuming that the underscore is a typo for the minus sign, the answer would be 0. Addition and subtraction are on the same level of precedence, so solve the problem from left to right: (12+12)-12+12-24= (24-12)+12-24= (12+12)-24= (24-24)=0
A pole 24 feet high has a shadow of 8 feet nearby is a 72 feet high pole how long is its shadow?
B! E! 24 ! 72 ! consider those two triangles that are similar A !____ D!____F 8 C ABC is similar to DEF so, AB BC AC __ = __ = __ DE EF DF 24 8 --- = --- 72 DF 72*8/24= 24 so the shadow is 24 feet long but im not that sure that the triangles are similar, if not then this is not true hope its right :D
Who are the mathematician behind the probability?
"A gambler's dispute in 1654 led to the creation of a mathematical theory of probability by two famous French mathematicians, Blaise Pascal and Pierre de Fermat. Antoine Gombaud, Chevalier de Méré, a French nobleman with an interest in gaming and gambling questions, called Pascal's attention to an apparent contradiction concerning a popular dice game. The game consisted in throwing a pair of dice 24 times; the problem was to decide whether or not to bet even money on the occurrence of at least one "double six" during the 24 throws. A seemingly well-established gambling rule led de Méré to believe that betting on a double six in 24 throws would be profitable, but his own calculations indicated just the opposite.
