Answer: 1/8 km
Step-by-step explanation:
3/8 * 1/3 = 1/8
Some symbols are missing. I'm assuming you meant to put in a horseshoe symbol like so

If so, then the contrapositive of that would be

which is the final answer.
The tilde sign

means "not" so writing

means "not q" which is the complete opposite of q.

See attached file for detailed solution of the given.
Using the normal distribution, it is found that the replacement time that separates the top 18% from the bottom 82% is of 11.23 years.
<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 mean and the standard deviation are, respectively, given by
.
The desired value is the 82nd percentile, which is X when Z = 0.915, hence:


X - 9.4 = 0.915(2)
X = 11.23
The replacement time that separates the top 18% from the bottom 82% is of 11.23 years.
