Bentley is working two summer jobs, babysitting and clearing tables. He can work at most 12 hours altogether between jobs in a given week. Write an inequality that would represent the possible values for the number of hours babysitting, b, and the number of hours clearing tables, c, that Bently can work in a given week.

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 25002500 grams and a standard deviation of 800800 grams while babies born after a gestation period of 40 weeks have a mean weight of 27002700 grams and a standard deviation of 385385 grams. if a 3232-week gestation period baby weighs 21252125 grams and a 4040-week gestation period baby weighs 23252325 grams, find the corresponding z-scores. which baby weighs lessless relative to the gestation period?
