As manager for a construction firm, you are in charge of bidding on two large contracts. you believe the probability you get contract #1 is 0.40.4. if you get contract #1, the probability you also get contract #2 will be 0.60.6, and if you do not get #1, the probability you get #2 will be 0.70.7. complete parts (a) through (c). a) sketch the probability tree.

the forst and 3rd

step-by-step explanation:

its a straight line parallel to the time axis

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
