9. The width of a rectangle is six inches less than its length. If the perimeter of this rectangle is 20 inches, find the width.

1) 6 inches
2) 2 inches
3) 8 inches
4) 4 inches

Plot the points (0,6), (3,15.8), and (9.5,0) using the graphing tool, and find the function

The accompanying normal probability plot was constructed from a sample of 30 readings on tension for mesh screens behind the surface of video display tubes used in computer monitors. does it appear plausible that the tension distribution is normal? the given probability is has a significant downward curve, so it is plausible that the tension distribution is normal. the given probability is has a significant downward curve, so it is not plausible that the tension distribution is normal. the given probability is quite linear, so it is plausible that the tension distribution is normal. the given probability is has a significant upward curve, so it is not plausible that the tension distribution is normal. the given probability is quite linear, so it is not plausible that the tension distribution is normal.
