A study by the department of education of a certain state was trying to determine the mean SAT scores of the graduating high school seniors. The study examined the
scores of a random sample of 90 graduating seniors and found the mean score to be
515 with a standard deviation of 103. At the 95% confidence level, find the margin of
error for the mean, rounding to the nearest tenth. (Do not write +).

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
