<h3>Question: Explain why the researchers used data from ten trails and averaged them, rather than data from a single trail.</h3>
Answer : Because in all experiments there are several factors that can affect the result. Repeating the experiment several times can vary the factors and compensate the measurement errors. Therefore, the average of the results is calculated to find the result that is closest to the set of all the results, being more reliable than a single result of an individual experiment.
Hope this helps!

Q is the ray that angle PQR and SQR shares. Because both angles has the ray of
Q.
ray refers to a line with one endpoint
P is a ray, Q is a ray, R is a ray and S is a ray. When you put them together, they form angle.

Answer:
- y = sin(2t)
- y = cos(2t)
Step-by-step explanation:
In the case of each of the answers listed above, the second derivative is equal to -4 times the function, as required by the differential equation.
For y = 2/3t^3, the second derivative is 4t, not -4y.
For y = e^(2t), the second derivative is 4y, not -4y.
__
The graph shows the sum of the second derivative and 4y is zero for the answers indicated above, and not zero for the other two proposed answers.
