Question

dimensional ____ is a mathematical technique that allows you to use units to solve problems involving measurements. 1 point your answer if you wanted to know how many milliseconds were in 3 seconds, you would need to write a conversion factor (also called an equivalence statement) with which units in the denominator? 1 point

Explanation:

1. Dimensional analysis is the mathematical technique for using units in measurement - related problems.
2. To convert 3 seconds to milliseconds, since 1 second = 1000 milliseconds, the conversion factor is $\frac{1000\ \text{milliseconds}}{1\ \text{second}}$, so seconds are in the denominator.

Answer:

1. analysis
2. seconds
