Answer:
And the margin of error with this one:
Step-by-step explanation:
Assuming that the parameter of interest is the sample mean 
. And we can estimate this parameter with a confidence interval given by this formula:
(1)
For this case the confidence interval is given by (1.9, 3.3)
Since the confidence interval is symmetrical we can estimate the sample mean with this formula:
And the margin of error with this one:
Answer: -23
Step-by-step explanation:
You need to first set up the equation:
It would look like 90 divided by 360 multiplied by the given
circumference which is 72 cm.
So 90 / 360 x 72
Simply the fraction above, it will give us:
¼ x 72
So the answer would be 18 cm that is the length of DE (minor
arc)
For this case we have the following vertices:
D = (- 1, -1)
E = (1, -1)
F = (- 1, -6)
Then, the vertices after the transformation are:
D '= (- 1, 1)
E '= (1,1)
F '= (- 1,6)
The x coordinate remains the same
The y coordinate change sign.
Therefore, the transformation is:
Reflection on the x axis.
Answer:
Reflection on the x axis.
