Aplane flying at an altitude of 3.0 mi is at a direct distance dequalsstartroot 9.0 plus x squared endroot from an airport control tower, where x is the horizontal distance to the tower. if the plane's speed is 380 mi/h, how fast is d changing when xequals6.6 mi?

Given the box plot, will the mean or the median provide a better description of the center? box plot with min at 10.5, q1 at 11.5, median at 12.5, q3 at 13.5, max at 15

How can you tell when x and y are not directly proportional?

Need 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.
