Answer:
4 in 4in 6 in = 96 in
Step-by-step explanation:
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:
The above answer explanation can be more clear by understanding that the population is the soil around the former waste dump and the samples are 16 which were taken from EPA.In report, the method is unclear too.
97. The great wall is more than 20 000 kilometers long. And about ¾ of it is considered as properly preserved.
I guess you are asking about the value of ¾ which is properly preserved in the said length of the great wall.
=> ¾ = 0.75
Thus, the formula would be like this:
=> 20 000 * .75 = 15 000
Thus, the ¾ value of great wall that is preserved is equals to 15 000 kilometers long,
Answer:
f(- 2) = 8
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x) , that is
f(- 2) = 2
- 4(- 2)³ - 11(- 2)² +3(- 2) - 6
= 2(16) - 4(- 8) - 11(4) - 6 - 6
= 32 + 32 - 44 - 12
= 64 - 56
= 8
