Inserting the formulas you found for xman(t) and xbus(t) into the conditionxman(tcatch)=xbus(tcatch) , you obtain the following-b+ct(catch) = 1/2 at^2( catch) or 1/2 at^2 (catch) - ct (catch) +b = 0intuitively, the man will not catch the bus unless he is running fast enough. in mathematical terms, there is a constraint on the man's speed (c) so that the equation above gives a solution for t catch that is a real positive number. find cmin the minimum value of c for which the man will catch the bus. express the minimum value for the man's speed in terms of a and b .

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
