When coin 1 is flipped, it lands on heads with probability . 4 ; when coin 2 is flipped, it lands on heads with probability . 7 . one of these coins is randomly chosen and flipped 10 times. what is the probability that the coin lands on heads on exactly 7 of the 10 flips? given that the first of these 10 flips lands heads, what is the conditional probability that exactly 7 of the 10 flips land on heads?

i dont know sorry

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

i suppose it should be (y=2x-5)
