Answer:
C. We have made a correct decision
Step-by-step explanation:
Hypotheses are:
: mu is less than or equal to 47
: mu is greater than 47
Type I error happens when we reject the null hypothesis but the null hypothesis was true
Type II error happens when we fail to reject the null hypothesis but the null hypothesis was wrong.
In this example we concluded that <em>mu is greater than 47,</em> thus we reject the null hypothesis. Since true mean is 52, this conclusion is true. We have made a correct decision
Answer:
{-9, -3, 0, 5, 7}
Step-by-step explanation:
The range of a function includes all possible output values.
In this particular case, the output values are the set {0, -3, -9, 5, 7}.
This is the answer. However, arranging the members of this set in ascending order leads to a nicer appearance: {-9, -3, 0, 5, 7}
The range of the given function is {-9, -3, 0, 5, 7}.
Answer: Option B.
Step-by-step explanation:
The equation of the line in Slope-intercerpt form is:
Where "m" is the slope of the line and "b" is the intersection of the line with the y-axis.
For the graph of the line , you can identify that:
And for , you can identify that:
Therefore, you can observe that the slope does not change, but now the line cuts the y-axis at . In other words, it was moved from to (3 units on the y-axis)
Then, it is the graph of translated 3 units upward, which means that the graph of g(x) is 3 units above the graph of f(x).
