Canceling units is also called: a. changing the value c. multiplication b. unit analysis d. making connections
SOVA2 [1]

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 * \frac{12 in }{1 ft}

3 ft = ( 3 * 12 )  in ⇒ 36 in

What is an equation of the line that passes through the points (6,5) and (7,7)
Morgarella [4.7K]

Answer:

The slope of the line is m = 2.

The y-intercept is (0,7).

The equation of the line in the slope-intercept form is y = 2 x - 7.

Step-by-step explanation:

The slope of a line passing through two points P = \left(x_{1}, y_{1}\right) and Q = \left(x_{2}, y_{2}\right)

is given by  m=\frac{y_{2}-y_{1}  }{x_{2} -x_{1} }

We have that x_{1} = 6 , y_{1} = 5y , and y_{2} =7.

Plug the given values into the formula for a slope: m=\frac{7-5}{7-6} =2.

Now, the y-intercept is b=y_{1} -mx_{1} (or b =y_{2} -mx_{2}, the result is the same).

b=5-(2)*(6)=-7

Finally, the equation of the line can be written in the form y=b+mx:

y=2x-7
