Answer:
x > 2
Step-by-step explanation:
Given
- 8x + 2x - 16 < - 5x + 7x ← simplify both sides
- 6x - 16 < 2x ( subtract 2x from both sides )
- 8x - 16 < 0 ( add 16 to both sides )
- 8x < - 16 ( divide both sides by - 8 )
Remembering to reverse the symbol as a consequence of dividing by a negative value.
x > 2
B) Minimum= 1
Q1= 3
Q3= 8
Lower Fence= Q1-(IQR*1.5)
= 3-(5*1.5)
= -4.5
Maximum= 11
Median= 7
IQR= 8= 3= 5
Upper Fence= Q3+(IQR*1.5)
= 8+(5*1.5)
= 15.5
c) No. All values are between the lower fence and the upper fence.
Simply then you get your answer
The answer is B- air pollution
