Hi! So this is just a simple probability question that seems a lot more complicated than it actually is. To find the probability that they only play clarinet, all you have to do is take 182 and subtract 86 because it eliminates the people that also play the flute. After doing this, you put your answer (96) and put it over the total amount of people (350). There for there is a 96 in 350 chance that they will only play clarinet.
The height of the hawk flying over the tree is 462.14 feet
<h3>How to find the height of the hawk using angle of elevation?</h3>
The observer (O) is located 660 feet from a tree (T).
The observer notices a hawk (H) flying at a 35° angle of elevation from his line of sight.
The situation forms a right angle triangle.
Therefore, using trigonometric ratios,
tan ∅ = opposite / adjacent
where
- ∅ = angle of elevation
- opposite side = height of the hawk
- adjacent side = distance of the observer from the tree
Therefore,
tan 35 = h / 660
cross multiply
h = 660 tan 35
h = 660 × 0.70020753821
h = 462.136975218
h = 462.14 feet
Therefore, the height of the hawk flying over the tree is 462.14 feet.
