<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!

Our friend's mistake when wanting to make a new mixture of pink paint is that she is only going to add 2 parts of white paint, the correct formula would be 3.
<h3>How to calculate how much paint you need to make 3 gallons of Pink paint?</h3>To mix 3 gallons of pink paint we must take into account the following information:
- 1 gallon of pink paint is equal to 3 parts red paint and 1 part white paint.
To find out how many parts we need to prepare 3 gallons of pink paint we must multiply the mix values for a gallon by 3.
Red paint:
- 3 x 3 = 9
White paint:
- 1 x 3 = 3
Based on the above, we need to use 3 parts white paint and 9 parts red paint to make 3 gallons of pink paint.

Answer:
The first occurence of t for which x = 0 is t = 0.5.
Step-by-step explanation:
The harmonic motion is described by the following equation.
What is the first occurrence of a value of t for which x = 0?
This is t when . So
The inverse of the cosine is the arcosine. So we apply the arcosine function to both sides of the equality.
The first occurence of t for which x = 0 is t = 0.5.
