Historically, there is a 40% chance of having clear sunny skies in seattle in july. let's assume that each day is independent from any other day (although this is not really true under this assumption, if you will spend 18 days in seattle in july, what's the probability of having clear sunny skies on at least 13 of those days? (a) solve this exactly (b) solve this by approximating using a normal distribution. 8.

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
