An observer (o) is located 500 feet from a school (s). the observer notices a bird (b) flying at a 39° angle of elevation from his line of sight. how high is the bird flying over the school? you must show all work and calculations to receive full credit.

a right triangle is shown with one leg measuring 500 and another leg measuring h with an angle across from it measuring 39 degrees.

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
