Suppose that a random man's height from a certain population has a normal distribution with mean of 70" and standard deviation of 3 and a random woman's height has a normal distribution with mean of 66' and standard deviation of 4". find the probability that a random woman is taller than a random man. (hint: the sum of two gaussian random yariables is a gaussian random variable with μ-hs and a variance of σ2-σ2+ ơy2).

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
