If ∆ABC has vertices A(1, 5), B(4, 7), and C(2, 1) and is reflected over the x-axis and then over the y-axis, what are the coordinates of ∆ABC after the sequence of transformation?

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?
