Summary statistics randomly selected weights of newborn baby girls, n=188, x=29.2hg, s=6.3hg, construct a confidence interval, estimate mean, use 95% confidence level.

Polygons efgh and e′f′g′h′ are shown on the coordinate grid: what set of transformations is performed on efgh to form e′f′g′h′? a. a translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin b. a translation 1 unit to the right followed by a 90-degree counterclockwise rotation about the origin c. a 90-degree clockwise rotation about the origin followed by a translation 2 units to the right d. a 90-degree clockwise rotation about the origin followed by a translation 2 units to the left

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827
