Answer:
(B)-x-(-x) =0
Step-by-step explanation:
<u>Option A</u>
Our equation is: -x +0+(- x) = 0
Left Hand Side:
-x +0+(- x) = -x-x=-2x
<u>Option B</u>
Our equation is: -x-(-x) =0
Left Hand Side:
-x-(-x) =-x+x=0
Therefore, the equation in Option B is true.
Mean = -2
Median = -1
Mode = Nil
Range = 38
Step-by-step explanation:
Given data is:
-18, 10, -20, -11, 9, 18
Arranging the data in ascending order
-20, -18, -11, 9, 10, 18
<u>Mean:</u>
Mean is given by the formula
Items are: 6
<u>Mode:</u>
Mode is the most frequent value in the data. So,
As there is no value repeated in the data. There is no mode
<u>Median:</u>
Median is the middle value of the data. As the no. of data value are even,
the average of middle 2 values is mode.
Note that the data has to be arranged in ordered to find median
Here,
<u>Range:</u>
Range is the difference between the largest and smallest value of the data
Here
Largest value = 18
Smallest value = -20
So,
Hence,
Mean = -2
Median = -1
Mode = Nil
Range = 38
Keywords: Data, Median
