2) Which of the following represents an equation of a line parallel to one whose equation is 2y + 8x = 18?

Reika [66]

Parallel has the same slope
2y + 8x = 18
Make it slope in form: y = mx + b
Divide the equation by 2
y + 4x = 9
Now subtract 4x
Y = -4x + 9
The slope is -4
Which equation also has same slope?

Solution: A

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

$M = \frac{1}{2}(\frac{n}{2}th\ value+(\frac{n}{2}+1)th\ value)$

Putting the values

$M = \frac{1}{2}(\frac{20}{2}th\ value+(\frac{20}{2}+1)th\ value)\\M=\frac{1}{2}(10th\ value +[10+1]th\ value]\\M= \frac{1}{2}(10th\ value + 11th\ value)$

The 10th value in dataset is 26 and 11th is also 26 so

$M = \frac{1}{2}(26+26)\\M = \frac{1}{2}(52)\\M = 26$

Hence,

The correct answer is: Option D: 26 vehicles
