Question4 The equation of a circle in general form is Ax2 + By2 + Cx + Dy + E = 0, where A = B ≠ 0. How do the coefficients C and D change as the center of the circle crosses over the x- and y-axes? How do the coefficients C and D change if the radius of the circle changes? Experiment with different circles using the general form of the equation in GeoGebra, if you wish.
I have the answer its below
If the center of the circle is to the right of the y-axis, C is negative and its absolute value increases as the center moves to the right. If the center is to the left of the y-axis, C is positive and its value decreases as the center moves to the right. D does not change when the center moves horizontally.
If the center of the circle is above the x-axis, D is negative and its absolute value increases as the center moves up. If the center is below the y-axis, D is positive and its value decreases as the center moves up. C does not change when the center moves vertically.
The values of C and D are not affected when the radius changes, as long as the center stays the same.

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.
