A coin is flipped 20 times. It lands on heads 11 times and tails 9 times. What is the theoretical probability that you will flip heads? Please show your work.

11/20

Step-by-step explanation:

probability-- number of favourable outcome/ number of total outcome

probability--11/20

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
