On the day of the field trip, each teacher must call the parents of any student who has not returned a
permission slip. all of mr. gomez's students returned their permission slips, so he did not have to make any
calls. mrs. hooper and mr. anderson had to call a total of eight parents. mrs. hooper needed to call two more
students than mr. anderson. which set of equations correctly describes the phone calls made? (let h = mrs.
hooper's calls and a = mr. anderson's calls.)

Tiara buys the pizza shown below: a circular pizza is shown. the edge of one slice is marked ab. what does the curve ab represent?

Is the number 128.439 a rational number

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.
