A frequency polygon is drawn by joining the mid-points of the bars in a histogram. Students can download the solutions and refer them to solve the exercise wise problems. A) The histogram is right-skewed, so the mean is less than the median. In both bar charts and histograms, tall bars show the common values of a variable, and shorter bars show less-common values. rotor structure = 120*rotor frequency/Poles = 120*2/4 = 60 rpm = 6.28 rad/s. The simplest example of a coordinate system is the identification of points on a line with real numbers using the number line.In this system, an arbitrary point O (the origin) is chosen on a given line.The coordinate of a point P is defined as the signed distance from O to P, where the signed distance is the distance taken as positive or negative depending on which side of the line P lies.
