Answer:
x = 5/7
Step-by-step explanation:
4 (0.25 - 2) = x - 0.75 (16 - 8x)
1 - 8 = x - 12 + 6x
1 - 8 + 12 = x + 6x
5 = 7x
5/7 = x

Step-by-step explanation:
Answer: 100.8
Step-by-step explanation:
Given that:
Standard deviation (σ) = 16
X > 100
From the z table :
Zscore = P(X > 100) = - 0.05
Zscore = - 0.05
Thus ;
Zscore = (x - m) / σ
x = 100
-0.05 = ( 100 - m) / 16
-0.05 * 16 = 100 - m
- 0.8 = 100 - m
m = 100 + 0.8
Mean = 100. 8
Mean score = 100.8
