The probability that Bill buys a dress shirt is .60. If he does buy the dress shirt, the probability that he buys a tie is .625. If he does not buy a dress shirt the probability that he buys a tie is .25. If you learn that bill bought a tie, what is the probability that he bought a dress shirt? (to nearest hundredths)

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

the answer is b.)

< 1=< 2

%40

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
