An elevator has a placard stating that the maximum capacity is 2400 16—15 passengers. So, 15 adult male passengers can have a mean weight of up to 2400/15 - 160 pounds. If the elevator is loaded with 15 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than
160 lb. (Assume that weights of males are normally distributed with a mean of 169 lb and a standard deviation of 35 lb.) Does this elevator appear to be safe?
The probability the elevator is overloaded is
(Round to four decimal places as needed.)

The method to find the female dormitory is 2-d=800

Ok here we go ..there are plenty of ways to solve such math problems but we will go for the smartest and easiest ..5x+2y=7  -2x+6y=9we rearrange them into the following ..by multiplying the 1st equation by 2 it becomes 10x + 4y = 14we rearrange it and so it becomes 10x = 14 - 4yas for the second equation we multiply it by 5 and rearrange it so it becomes as to the following ..-10x + 30y = 45rearranging so 10x = 30y -45now 10x equals both 14 - 4y and 30y -45so   14 - 4y = 30y -4531 = 26yy= 31/26 = 1.19 or around 1.2so by now we can calculate x easily as  -2x+6y=9so 2x = 6y -9 = 6 * 31/26 - 9 = -1.84  then x = - 0.92 or around -0.9best luck!
