Aparticular brand of dishwasher soap is sold in three sizes: 25 oz, 40 oz, and 65 oz. twenty percent of all purchasers select a 25-oz box, 50% select a 40-oz box, and the remaining 30% choose a 65-oz box. let x1 and x2 denote the package sizes selected by two independently selected purchasers. a. determine the sampling distribution of x, calculate e(x), and compare to m. b. determine the sampling distribution of the sample variance s2 , calculate e(s2 ), and compare to s2 .

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
