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:
The answer is option D
32 + (4c − 6c) + (2 + 6c)
c = 5
32 + ( 4(5) - 6(5)) + (2 + 6 (5)
= 32 + (20 - 30) + ( 2 + 30)
= 32 - 10 + 32
= 54
