Why not? Because every math system you've ever worked with has obeyed these properties! You have never dealt with a system where a×b did not in fact equal b×a, for instance, or where (a×b)×c did not equal a×(b×c). Which is why the properties probably seem somewhat pointless to you. Don't worry about their "relevance" for now; just make sure you can keep the properties straight so you can pass the next test. The lesson below explains how I kept track of the properties.
11z > -33
11z / 11 > 33 / 11
z > 3

Answer:
The correct answer is: Option D: 26 vehicles
Step-by-step explanation:
Median is the middle value of a sorted data set.
The formula for median depends on the number of values in the dataset.
First of all we have to arrange the given data in order
So,
14 19 23 24 24 24 24 26 26 26 26 26 27 27 28 29 30 30 30 34
Counting the values in the dataset
n = 20
As the number of values is even, the formula for median will be

Putting the values
![M = \frac{1}{2}(\frac{20}{2}th\ value+(\frac{20}{2}+1)th\ value)\\M=\frac{1}{2}(10th\ value +[10+1]th\ value]\\M= \frac{1}{2}(10th\ value + 11th\ value)](https://tex.z-dn.net/?f=M%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28%5Cfrac%7B20%7D%7B2%7Dth%5C%20value%2B%28%5Cfrac%7B20%7D%7B2%7D%2B1%29th%5C%20value%29%5C%5CM%3D%5Cfrac%7B1%7D%7B2%7D%2810th%5C%20value%20%2B%5B10%2B1%5Dth%5C%20value%5D%5C%5CM%3D%20%5Cfrac%7B1%7D%7B2%7D%2810th%5C%20value%20%2B%2011th%5C%20value%29)
The 10th value in dataset is 26 and 11th is also 26 so

Hence,
The correct answer is: Option D: 26 vehicles
