A chemist creates 230 milliliters of a 42.5% alcohol solution by combining a 30 % alcohol solution with a 55 % alcohol solution. If x represents the amount of the 30 % alcohol solution used and y
represents the amount of the 55 % alcohol solution used, which of the following equations model
the given infromation?

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.
