Suppose that aircraft engines operate independently and fail in-flight with a probability of 5%. assuming (a) that a multi-engine plane arrives safely if at least half of the engines run the entire time and (b) that you would like to arrive safely, should you prefer to take a 2-engine plane or a 4-engine plane?

Prove the converse of the pythagorean theorem using similar triangles. the converse of the pythagorean theorem states that when the sum of the squares of the lengths of the legs of the triangle equals the squares length of the hypotenuse, the triangle is a right triangle. be sure to create and name the appropriate geometric figures.
