Answer: x = -2
Step-by-step explanation:
1. Distribute the 2: (2 * 5x) + (2 * 5)
3x - 4 = 10x + 10
2. Subtract 3x from both sides
-4 = 7x + 10
3. Subtract 10 from both sides
-14 = 7x
4. Divide both sides by 7
-2 = x
or
x = -2
Answer:
Option D) s = 1
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 69
X = 68
Formula:
Computing z-scores for different standard deviation:
The standard deviation with highest z-score gives the most extreme position in the distribution.
Thus, the most extreme position of X = 68 in the distribution is given by a standard deviation of 1.
Option D) s = 1
