An average of m=786 per meal with a=85 for n=100 children and adolescents before the labeling, compared to an average m=772 of with s=91 for a similar sample of n=100 after the mandatory posting. use a two-tailed test with alpha=.05 to determine whether the mean number of calories after the posting is significantly different than before calorie content was posted.

Subscriptions to a popular fashion magazine have gone down by a consistent percentage each year and can be modeled by the function y = 42,000(0.96)t. what does the value 42,000 represent in the function?

2. explain in words how you plot the point (4, −2) in a rectangular coordinate system.

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
