Answer:
- Population: Soil around a former waste dump
- Parameter: Concentrations of toxic chemicals
- Sample frame: Accessible soil around dump
- Sample: 16 soil samples
- Method: Unclear
- Bias: Uncertain if soil samples were randomly chosen
Step-by-step explanation:

Rational numbers end
irrational numbers do not
pi is an irrational number
√2 is an irrational number
so
√50=√2 times √25=√2 times 5
irrational times rational =irrational
√2=irrational
answer is false, it is rrational
Answer:
32
Step-by-step explanation:
The shape in image is an equilateral triangle which means all of it's angles has equal measurements:
2x - 4 = 5y and that is equal to 60 degrees
2x - 4 = 60 add 4 to both sides
2x = 64 divide both sides by 2
x = 32
