Andrew is trying to create a number puzzle for his younger sister to solve. he challenges his sister to find the mystery number. “when is 8 subtracted from half number of a number, the result is 10” the equation to represent the mystery number is 1/2x - 8 = 10 , andrews sister tries to guess the mystery number. andrews sister makes three guesses to what the answer is. she guesses. 4, 18 and 36. which one is correct ?

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.
