The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 32 hours and the median is 28.2 hours. Twenty-four of the families in the sample turned on the television for 17 hours or less for the week. The 11th percentile of the data is 17 hours. Step 2 of 5 : Approximately how many families are in the sample? Round your answer to the nearest integer.

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
