Step-by-step explanation:
Answer:
The required range of the function 
is [-7,-1]
Step-by-step explanation:
Given : Function
To find : What is the range of the given function?
Solution :
The range is defined as the variation in which any function is defined.
We know that the sin function lies between [-1,1]
.....(1)
The required function is
Multiply equation (1) by -3
.....(2)
Now, we subtract equation (2) by 4
Therefore, The required range of the function is [-7,-1].
Answer:
A, the solutions are x=3,2
Step-by-step explanation:
Answer:
The z-statistic lies in the critical region
Step-by-step explanation:
When a hypothesis test is performed, the decision to reject or not reject the null hypothesis is made on basis of following observations:
- If the z-statistic falls in the critical or rejection region, there is enough evidence to reject the Null Hypothesis
- If the z-statistic falls outside the critical or rejection region, there is not enough evidence to reject the Null Hypothesis.
In the given statement Zachary rejects the Null Hypothesis, this means the z-statistic she calculated must have been inside the critical or rejection region. Hence the correct answer would be:
The z-statistic lies in the critical region
