Answer:
<em>D. y=-3x</em>
Step-by-step explanation:
<u>Direct Proportion</u>
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
Where k is the constant of proportionality.
Solving for y:
y=kx
The only choice representing a direct proportion is:
D. y=-3x

Answer:
The value is not close to 0.3 because of sampling variability.
Step-by-step explanation:
The group of answer choices are not given which are as follows:
- All of the above
- Because the sample size is too small
- Because of sampling variability
- Because of nonresponse bias
From this the correct option is option C which is Because of Sampling Variability.
This is true because the two populations are of different values and thus the sample is not dependent on any one of the two possibilities. When a sample of 4 is considered from first and 400 from the second the overall probability will be far from the value of 0.3. So the
