<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.

I. The value of x is equal to 8.
II. The dimensions of the rectangle are 13 and 5 inches respectively.
<u>Given the following data:</u>
- Area of a rectangle = 65 square inches.
- Length of rectangle = x + 5 inches
- Width of rectangle = x - 3 inches
To find the value of x, and the dimensions of the rectangle:
Mathematically, the area of a rectangle is given by the formula:
Substituting the values, we have:
x = 8 or x = -10
<u>For the</u><u> length:</u>
when x = 8
Length = 13 inches.
<u>For the</u><u> width:</u>
when x = 8
Length = 5 inches.
