i think it’s HL But idk

i have no idea what your're talking about when you say HL i cant even see all the answer choices bu they are congruent because they are supplementary right angles so i hope that helps :)

Step-by-step explanation:

-2.5

Step-by-step explanation:

Here in this question, we are interested in calculating the z-score for a student that had a particular mark at the test

To calculate the z-score, we need to use a mathematical formula

Mathematically;

z-score = (x - mean)/SD

From the question;

x = 76

mean = 86

standard deviation SD = 4

Plugging these values in the equation, we have;

z-score = (76-86)/4 = -10/4 = -2.5
