On a coordinate plane, a piecewise function has two lines. The first line has an open circle at (negative 1, 3) and continues horizontally along y = 3 with an arrow instead of an endpoint. The second line has a closed circle at (negative 1, negative 2) and goes down toward (5, negative 5), with an arrow instead of an endpoint. A linear piecewise function is represented by the graph.
Use the graph to evaluate the function.
When x = –5, y = .
When x = –1, y = .
When x = 3, y = .

Don't know how to find x given these segment lengths

Which equation represents the function on the graph?

Me 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.
