The figure below shows triangle nrm with r2 = m2 + n2: triangle nrm has legs m and n, and r is the length of its longest side. ben constructed a right triangle efd with legs m and n, as shown below: triangle efd has legs m and n and hypotenuse f. he made the following table to prove that triangle nrm is a right triangle: statement reason 1. r2 = m2 + n2 given 2. f2 = m2 + n2 pythagorean theorem 3. f2 = r2 substitution 4. f = r square root property of equality 5. triangle nrm is congruent to triangle efd ? 6. angle nrm is a right angle cpctc 7. triangle nrm is a right triangle angle nrm is a right angle which reason best fits statement 5? sss postulate sas postulate aaa postulate aas postulate

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
