These are the hourly salaries od all workers employed at the Manhattan Law Firm together with the probabilities

hourly salary in dollars 8 90 125 180 350
probability (distribution) of having such a salary .1 .2 .5 .1 .1

The standard deviation for this salary distribution is approximately

only 10/60 isn't equivalent

hope this : )

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
