um take home test...i have no idea what im doing always sometimes never 1. sin2x=2sinx 2. cos (pie/3+x)=-sinx 3. if tan x=3 and tan y=2 then tan (x+y)=5 4. when you use the half angle formulas you choose whether to use a + or - by noting in which quadrant the angle lies 5. ...

circular (trigonometric) functions
hi, i need help solving this trigonometric equation: sinx+3cosx=0 i don't know what to do as i can't just diviide the two to create tanx which is what i have been doing in previous questions... yes, you are on the right track sinx = -3cosx sinx/cosx = -3 tanx = -3 so x must be...

the prob of a spade and a heart = 2(13/52)(13/51) = 13/102 so the prob of NOT a spade and a heart = 1 - 13/102 = 89/102 so the odds in favour of drawing a spade and a heart is 13:89

same argument as the previous question... find prob of at least one head = 7/8 etc

probability of an incorrect address = 5/100 to have atleast 1 incorrect address out of the 12 customers (choice of 1 out of 12 customers) 12C1 x (5/100) = (12!/ 1! 11!) (5/100) = 12 x (5/100) = 60/100 So for none to be incorrect it will be (1 - Prob of atleast one to be ...

She wins if 1. she draws a heart, but not the ace of heart (40 cents) Prob = 12/52 2. she draws an ace , but not the ace of heart (50 cents) prob = 3/52 3. she draws the ace of hearts ( 90 cents) prob = 1/52 expected return = (12/52)(40) + (3/52)(50) + (1/52)(90) = 13.8 cents ...
