Answer:
52
Step-by-step explanation:
Given that :
Mean (m) = 78
Standard deviation (s) = 13
Score that is 2 standard deviations below the mean
Using the relation :
Zscore = (x - m) / s
2 standard deviations below the mean means a Zscore of - 2
Hence,
-2 = (x - 78) / 13
Cross multiply
-2 * 13 = x - 78
-26 = x - 78
x = - 26 + 78
x = 52
Score which is 2 standard deviations below the mean is 52

Answer:
No solution
Step-by-step explanation:
3 x + y = 4 (1)
− 3 x − y = − 8 (2)
Add (1) and (2)
0 + 0 = -4
0 = -4 is a false statement
So, no solution
