Jorge earned a 75% on his History test where the class mean was 70% with a standard deviation of 5.2. He also earned a 82% on Math test where the class average is 84% with a standard deviation of 2.7.
Find the Z-scores for each of Jorge's tests. In which class did he do better relative to his peers? How do you know?

Plz (02.03 mc) which sequence of transformations will change figure pqrs to figure p′q′r′s′? (5 points) select one: a. counterclockwise rotation about the origin by 90 degrees followed by reflection about the x-axis b. counterclockwise rotation about the origin by 90 degrees followed by reflection about the y-axis c. counterclockwise rotation about the origin by 180 degrees followed by reflection about the x-axis d. counterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axis

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Asap! i'm not good math and i'm lost.
