4. A laser beam travels along a straight path for a certain distance, and then bounces n times off tilted mirrors before striking a target. The laser beam travels v2 additional

centimeters each time it bounces off a mirror. When there are 5 bounces, the laser

beam travels 13v2 cm.

a. Let d (n) denote the distance the laser travels in cm as a function of the number

of bounces off a mirror, n. What does d(5) represent? What is the value of d(5)?

Find the value of x that will make l ll m

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.
