Expo dry-erase markers are typically considered some of the best in the industry for their clarity and lifespan. A major competitor named Whypo claims that their markers last longer on average than Expo markers and they attempt to show this fact by using a random group of 15 Whypo markers. Whypo finds that their markers have a mean lifespan of 32 days, with a standard deviation of 8 days. Typically, an Expo marker under daily use will have a lifespan of 20 days before needing to be replaced
Check the conditions for Whypo's Hypothesis

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
