Answer:
5/8
Step-by-step explanation:
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

Answer:
We can calculate supplementary angles by subtracting the given one angle from 180 degrees. To find the other angle, use the following formula: ∠x = 180° – ∠y or ∠y = 180° – ∠x where ∠x or ∠y is the given angle.

Answer:
x=−y−3
Step-by-step explanation:
x+y=−3
Step 1: Add -y to both sides.
x+y+−y=−3+−y
x=−y−3
