Find the probability that the student was male, given the student chose to fly as their superpower

30/40 or P(male ∣ fly)=43=0.75

Step-by-step explanation:

The condition is that the student chose to fly as their superpower. There were 40 total students in the sample who chose to fly, and 30 of them were male.

P(male ∣ fly)= 30/40= 3/4=0.75

P(male ∣ fly)= P(male and fly)/ P(fly)

=30/100/40/100= 0.30/0.40= 3/4= 0.75

P(male ∣ fly)=3/4=0.75

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
