One factor in the development of tennis elbow, a malady that strikes fear into the hearts of all serious players of that sport (including one of the authors), is the impact-induced vibration of the racket-and-arm system at ball contact. It is well known that the likelihood of getting tennis elbow depends on various properties of the racket used. Consider the accompanying scatterplot of x = racket resonance frequency (in hertz) and y = sum of peak-to-peak acceleration (a characteristic of arm vibration, in meters per second per second) for n = 23 different rackets. Discuss interesting features of the data and of the scatterplot.
a. There are several observations that have identical or nearly identical x-values yet different y-values. Therefore, the value of y is not determined solely by x, but also by various other factors.
b. There are several observations that have identical or nearly identical x-values yet different y-values.
Therefore, the value of y is not determined by x.
c. There appears to be a general tendency for y to increase in value as x increases in value.
d. There appears to be a general tendency for y to decrease in value as x increases in value.
e. There are two data points which are far removed from the remaining data points. These two data points have large x-values and small y-values. Their presence might have an undue influence on a line fit to the data.
f. There are three data points that are far removed from the remaining data points. These three data points have small x-values and small y-values. Their presence might have an undue influence on a line fit to the data.

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
