Using the normal distribution, it is found that the life span of an appliance that has a z-score of –3 is of 24 months.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
In this problem, the parameters are given as follows:
.
Hence:


X - 48 = -24
X = 24.
The life span of an appliance that has a z-score of –3 is of 24 months.

Answer:
If you use the addition property of equality, what number would you add to both sides of the equal sign to isolate the variable?
You would subtract 5/7 from both sides of the equation
What is the solution?
x = 26/7 or 3 and 5/7
Step-by-step explanation:
x + 5/7 = 31/7
Subtract 5/7 from both sides of the equation:
x + 5/7 - 5/7 = 31/7 - 5/7
x = 26/7
