OPTOMETRY Color blindness occurs in 4% of the male population. Design a simulation that can be used to estimate the probability that a randomly chosen male will be color blind.

Solve the given system of equations. 2y= -x+9 , 3x-6= -15

Now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.

Atriangle has side lengths of x, x+11, and 3x+5. what is the perimeter?
