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:
530 m²
Step-by-step explanation:
First of all we need to label the missing sides ,please check the figure I provided for that :
x = 37 - (10+ 15) = 37 - 25 = 12
z = 10
y = 2 × 10 = 20
The shade does area = area of the whole rectangle − the white area
= 37 × 20 − [ (15×20)÷2 + (10×12)÷2 ]
= 740 − [ 150 + 60 ]
= 740. − 210
= 530
