Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. the aircraft can carry 4040 passengers, and a flight has fuel and baggage that allows for a total passenger load of 6 comma 7606,760 lb. the pilot sees that the plane is full and all passengers are men. the aircraft will be overloaded if the mean weight of the passengers is greater than startfraction 6 comma 760 l b over 40 endfraction equals 169 6,760 lb 40=169 lb. what is the probability that the aircraft is overloaded? should the pilot take any action to correct for an overloaded aircraft? assume that weights of men are normally distributed with a mean of 180.2180.2 lb and a standard deviation of 3838.

A geometric progression is a sequence of numbers in which each value (after the first) is obtained by multiplying the previous value in the sequence by a fixed value called the common ratio. for example the sequence 3, 12, 48, 192, ... is a geometric progression in which the common ratio is 4. given the positive integer ratio greater than 1, and the non-negative integer n, create a list consisting of the geometric progression of numbers between (and including) 1 and n with a common ratio of ratio. for example, if ratio is 2 and n is 8, the list would be [1, 2, 4, 8]. associate the list with the variable geom_prog.
