The equations of three lines are given below. 3
Line 1: y=
4
-x-8
Line 2: 4y=3x+5
Line 3: 8x+6y=-2
For each pair of lines, determine whether they are parallel, perpendicular, or neither.

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?
