Andre recorded the movement of a pendulum for 20 seconds. when he began, the pendulum was at its resting position. it then moved right (positive displacement) and left (negative displacement) several times. the time it took to move to both sides and then return to its resting position was 4 seconds. the pendulum's farthest position to either side was 8 cm. graph the pendulum's displacement as a function of time. allow the x-axis to be measured in seconds and the y- axis to be measured in cm.

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.

The description below represents function a and the table represents function b: function a the function is 5 more than 3 times x. function b x y −1 2 0 5 1 8 which statement is correct about the slope and y-intercept of the two functions? (1 point) their slopes are equal but y-intercepts are not equal. their slopes are not equal but y-intercepts are equal. both slopes and y intercepts are equal. neither slopes nor y-intercepts are equal.
