I think it is moving backward because when a car is parking and you are leaving, then you would be moving backward.
Hope this helped☺☺
Answer: c) increase
Step-by-step explanation:
- A sample is a finite subset of the entire population on which research statistical test regarding his/ her objective .
As the sample size increases it comes closer to the population size, and so converge to a better result of researcher's analysis.
It means the size of the sample is proportional to the power of their statistical tests.
∴ As the size of the sample increases the power of statistical test increases.
Hence, If a research team increases the sample size for a study, the power of their statistical tests will <u>increases</u>.
Therefore , the correct answer is : c) increase
Answer:
Hence, the graph is decreasing in the interval: –4 ≤ x ≤ 2 ( option: B is correct)
Step-by-step explanation:
We have to define the interval in which the graph of the given function is decreasing.
Clearly by looking at the graph we could see that the graph is first increasing till x<-4.
and then it decreases in the interval [-4,2] since the value of y changes from y=9 at x= -4 to y= -9 at x=2.
also after x=2 the graph increases till x=6 and after x=6 the graph is constant i.e. the graph is represented by the line:
y=5 in the interval x≥6.
Hence, the graph is decreasing in the interval:
–4 ≤ x ≤ 2 ( option: B is correct)
