Answer:

<em>(F).</em>

Step-by-step explanation:

P( - 7, 7)

R( - 4, 3)

m_{PR} = \frac{3-7}{-4-(-7)} = - \frac{4}{3}

R( - 4, 3)

T(2, - 5)

m_{RT} = \frac{-5-3}{2-(-4)} = - \frac{8}{6} = - \frac{4}{3}

m_{PR} = m_{RT}

Thus, the answer is <em>(F).</em>

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

sashaice [31]

Answer:

Cost of medium iced caramel latte = $3.59

x + y = 5.18......eq1

On Friday

2x + 3y = 11.95.....eq2

Eq1 × 3

3x + 3y = 15.54......eq3

eq3 - eq2

x = 3.59

Cost of medium iced caramel latte = $3.59
