Answer:
Option (3)
Step-by-step explanation:
Since domain of a function graphed is defined by the x-values and range by y-values.
When a function is reflected across x-axis rule to be followed,
(x, y) → (x, -y)
That means y-coordinates of all the ordered pairs given on the graph will get changed after the reflection across x-axis.
But x-values will remain same.
Therefore, domain of the function will stay the same and range will change.
Option (3) will be the answer.
256 is the answer hope that helped.
Answer:
Step-by-step explanation:
The owner of the store has determined that home delivery will be successful if the average time spent on the deliveries does not exceed 34 minutes. This is the null hypothesis. It is written as
H0 : µ ≤ 34
The alternative hypothesis would be
Ha : µ > 34
This is a right tailed test because of the greater then symbol in the alternative hypothesis. Since the p value for the test was found to be 0.0281281, if we use a significant level of 0.05, then the conclusion would be
Reject the null hypothesis. Therefore, At a 5% level of significance, the sample data showed significant evidence that the average time spent on the deliveries does exceed 34 minutes.
Answer:
OL and M
Step-by-step explanation:
(1)
270° ÷ 30° = 9
Count 9 dashed lines from OJ counterclockwise, then
OJ → OL
(2)
120° ÷ 30° = 4
Count 4 dashed lines from R counterclockwise, then
R → M
