Yong is measuring two pyramids whose bases are rectangles. Given the length and width of the base of the first pyramid, as well as its volume V, Yong uses the formula
h=3v/lxW
to compute its height h to be 7 centimeters.

The second pyramid has the same volume and base length, but its base's width is 2 times as long. What is its
height?

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?
