Given: Sine (A) = StartFraction 5 Over 13 EndFraction, StartFraction pi Over 2 EndFraction < A < Pi and Tangent (B) = negative StartRoot 13 EndRoot, StartFraction pi over 2 EndFraction < B < Pi What is tan(A – B)?

StartFraction 5 + 12 StartRoot 13 EndRoot Over 12 minus 5 StartRoot 13 EndRoot EndFraction
StartFraction 12 minus 5 StartRoot 13 EndRoot Over 5 + 12 StartRoot 13 EndRoot EndFraction
StartFraction 12 + 5 StartRoot 13 EndRoot Over negative 5 + 12 StartRoot 13 EndRoot EndFraction
StartFraction negative 5 + 12 StartRoot 13 EndRoot Over 12 + 5 StartRoot 13 EndRoot EndFraction

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores

Finally, the arena decides to offer advertising space on the jerseys of the arena’s own amateur volley ball team. the arena wants the probability of being shortlisted to be 0.14. what is this as a percentage and a fraction? what is the probability of not being shortlisted? give your answer as a decimal. those shortlisted are entered into a final game of chance. there are six balls in a bag (2 blue balls, 2 green balls and 2 golden balls). to win, a company needs to take out two golden balls. the first ball is not replaced. what is the probability of any company winning advertising space on their volley ball team jerseys?
