A group of scientists studied the amount of erosion at a beach. The scientist determined that the equation y=-0.5x+26 models the amount of shoreline, y,in feet, x decades after 1950.What state is true based on the model?

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.

This graph shows which inequality? a ≤ –3 a > –3 a ≥ –3 a < –3

From the top of a tree a bird looks down on a field mouse at an angle of depression of 50°. if the field mouse is 40 meters from the base of the tree, find the vertical distance from the ground to the bird's eyes.
