Canceling units is also called unit analysis.
This is also called dimensional analysis.
What is a unit of analysis in statistics?
- The unit of analysis is the entity that you're analyzing. It's called this because it's your analysis (what you want to examine) that determines what this unit is, rather than the data itself.
- Because it is the analysis you do in your study that determines what the unit is.
- For instance, if you are comparing the children in two classrooms on achievement test scores, the unit is the individual child because you have a score for each child.
For example -
1 ft = 12 in
3 ft = 
3 ft = ( 3 * 12 ) in ⇒ 36 in

Answer:
160.9 feet
Step-by-step explanation:
The function h(t) = 200 – 17t represents the height of a ball (in feet) dropped from 400 feet after t seconds.
After 2.3 seconds,
h(t) = 200 – 17t
h(2.3) = 200 – (17 X 2.3)
= 200 - 39.1
=160.9 feet
After 2.3 seconds, the ball drops to a height of 160.9 feet.
