Suppose that 63% of people own dogs. If you pick two people at random, what is the probability that they both own a dog?

3.175 i believe :)

Step-by-step explanation:

63/100. 2/1

Cross multiply = 200

Then divide 200÷63= 3.175

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
