Answer:
33 and 10.5
Step-by-step explanation:
The median is the middle number in the data set arranged in ascending order.
If there is no exact middle value then it is the average of the 2 numbers either side of the middle.
X 20 25 29 33 38 42 43
↑ middle number
Thus the median = 33
Arrange set F in ascending order.
F 1 2 4 6 15 20 24 28
↑ middle between 6 and 15
Thus the median = =
= 10.5

Area of the figure = 27 square units
Solution:
Number of full squares shaded = 24
Number of half squares shaded = 0
Number of more than half square shaded = 3
Number of less than half square shaded = 4
Area of the figure = Number of full square + Number of more than half square
+ Half of number of half squares
= 24 + 3
= 27 square units.
Area of the figure = 27 square units
