Quadrilateral PQRS is dilated by a scale factor of 1/2 with point R as the center of dilation, resulting in the image P'Q'R'S'.
1 answer:
The statement that is true about line segment P'S' is (c) Segment P'S' s 4 units long and lies on a different segment
<h3>How to determine the true statement?</h3>The complete question is in the attached image
From the image, we have:
PS = 8 units
This means that:
P'S' = 1/2 * PS
So, we have:
P'S' = 1/2 * 8
Evaluate
P'S' = 4
Also, the segment PS and P'S' do not lie on the same segment
Hence, the true statement is (c)

Last option
Step-by-step explanation:
If we extract a sample of size n from a normal population and we want to estimate the population mean then the confidence interval for the mean will be:
Where
Where is an estimator for the mean μ.
n is the sample size and s is its standard deviation.
is the level of significance
= 1-Confidence Level
Then
Then the 99% confidence interval for the population mean is
