(30 points, again) An air traffic controller is tracking two planes. To start, Plane A is at an altitude of 3015 feet and Plane B is just taking off. Plane A is gaining altitude at 30.5 feet per second and Plane B is gaining altitude at 80.75 feet per second. How many seconds will pass before the planes are at the same altitude? (in seconds) What will their altitude be when they're at the same altitude? (in feet)

Nikolas calculated the volume of the prism. his work is shown below.

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?
