Hugo has a pin attached to one of the spokes of his bike's wheel, for decoration. The height of the pin above the ground, in centimeters, is modeled by H(t) where t is the time in seconds. The function is
graphed below, along with one segment highlighted.

Me what is the value of x? showing work would be appreciated - ! : )

Express -5 2/5 as an improper fraction.

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.
