Suppose that two different tests A and B are to be given to a student chosen at random from a certain population. Suppose that the mean score on test A is 85 with a standard deviation of 10; the mean score on test B is 90 with a standard deviation of 16; the scores on the two tests have a bivariate normal distribution; and the correlation of the two test scores is 0.8. If the student's score on test A is 80, what is the probability that their score on test B will exceed 90

List the sides of δrst in ascending order (shortest to longest) if: m∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12

Ade and abc are similar. which best explains why the slope of the line between points a and d is the same as the slope between points a and b?

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
