The astronomical unit (au) is the mean distance from the sun to the earth. 1 au = 1.5 × 10,superscript,8,baseline, km (kilometers) if a comet is 2.3 au from the earth, how many km away is the comet? answer options with 5 options a. 3.45 × 10,superscript,8,baseline, km b. 6.52 × 10,superscript,7,baseline, km c. 3500 km d. 3.45 × 10,superscript,10,baseline, km e. 6.52 × 10,superscript,10,baseline, km

The sum of the reciprocal of a positive number and the reciprocal of 2 more than the number is 3/4 equation: the number is

4. bob solved the inequality problem below incorrectly. explain his error and redo the problem showing the correct answer. −2x + 5 < 17 −2x + 5-5 < 17-5 -2x/-2 < 12/-2 x < -6

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.
