Answer:
the answer is c) 1.08
Step-by-step explanation:
Step1:
Formula for calculating z-score is;
Z= (x-mean)/standard deviation
where x is the value for which z-score is required
Step 2:
As asked in the question z-score for highest grade is required which is 91;
z= (91-81)/9.3
z=10/9.3
z=1.075
which is approximately;
z=1.08
Answer:
slope = -1/2
Step-by-step explanation:
we use point B and point A to find the slope
A(-2,1) B(-4,2)
-2 = x1
1 = y1
-4 = x2
2 = y2
the formula for slope is: y/x = y1 - y2 / x1 - x2 = 1 -2 / -2-(-4) = -1/2
