An airliner carries 100 passengers and has doors with a height of 76 in. Heights of men are normally distributed with a mean of
69.0 in and a standard deviation of 2.8in. a. If a male passenger is randomly selected, find the probability that he can fit through the doorway without bending. (Round to four decimal places as needed.)

y= science problems
x +y =42
x= y+10
Substitute: (y+10) + y =42
Combine y: 2y +10=42
Solve for y: y= 16
