Answer:
C
Step by step explanation:
When you move a shape via rigid transformations, the dimensions of the shape do not change (by definition). This includes translation and rotation. Since the size or measure of any of the side lengths or angles is not changing when you move the shape, the only way that you can match one shape onto another with rigid transformations is if all of the corresponding sides and angles are congruent. Therefore, the correct answer is choice C. Hope this helps!
For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98
<h3>What is a sample size?</h3>
The sample size is a term used in market research for defining the number of subjects included in a sample size. By sample size, we understand a group of subjects that are selected from the general population and is considered a representative of the real population for that specific study.
Empirical rule states that for a normal distribution, 68% of the values are within one standard deviation from the mean, 95% of the values are within two standard deviation from the mean and 99.7% of the values are within three standard deviation from the mean.
For a population mean of 20.15 and a standard deviation of 3.7
68% are within μ ± σ/√n,
hence,
68% = 20.15 ± 3.7/√20 = (19.32, 20.98)
For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98.

Step-by-step explanation:
Olivia is correct. Each O is opposite of the angle θ, and each A is adjacent.
Paula's first triangle was correct. But on the second triangle, she reversed the O and A.
So the equation is parallel and the slope will be 2
y=2x+b
sub in(5,4) for x and y to find b
4=2(5)+b
4-10=b
b=-6
therefore the equation is y=2x-6
