Part a: explain why the x-coordinates of the points where the graphs of the equations y = 4–x and y = 2x + 3 intersect are the solutions of the equation 4^–x = 2^x + 3. (4 points)

part b: make tables to find the solution to 4^–x = 2^x + 3. take the integer values of x between −3 and 3. (4 points)

part c: how can you solve the equation 4^–x = 2^x + 3 graphically? (2 points)

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?
