Adiamond merchant has a chance to buy one of 4 diamonds and wants to sell it immediately. one costs only $1000, but he has a 90% chance of getting $5000 for it (or not selling it at all). the second costs $10,000, and he has a 60% change of selling it for $25,000 (or not selling it at all). the third costs $20,000, but he has a 50% chance of selling it for $60,000 (or not selling it at all). the last diamond costs $50,000, but he has a 1% chance of selling it for $1,000,000 (or not selling it at all). which diamond gives him the best expected value?

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
