The position of a particle moving to the right on the x x -axis is given by x(t) x ( t ) , where x(t) x ( t ) is measured in inches and t t is measured in minutes for 0≤t≤100 0 ≤ t ≤ 100 . If y=x(t) y = x ( t ) is a linear function, which of the following would most likely give the best estimate of the speed of the particle, in inches per minute, at time t=20 t = 20 minutes?

According to a study done by de anza students, the height for asian adult males is normally distributed with an average of 66 inches and a standard deviation of 2.5 inches. suppose one asian adult male is randomly chosen. let x = height of the individual. a) give the distribution of x. x ~ b) find the probability that the person is between 64 and 69 inches. write the probability statement. what is the probability?
