Your answer will be D
As y = -(x+2)(x-1)
Thus the external negative sign will flip the positive 2 into a negative & negative 1 into a positive; Resulting, y=(x-2)(x+1)
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.
Answer: The value of c would be 26.514 lb.
Step-by-step explanation:
Since we have given that
Mean = 17 lb
Standard deviation = 3.3 lb
At 99% level of significance, z = 2.58
So, it becomes,
So, the weight c would be
Hence, the value of c would be 26.514 lb.
Answer:
4.7
Step-by-step explanation:
Given equation y=4.7x
constants of proportionality = y/x
so, y/x = 4.7
therefore, answer is 4.7
