Give an example of where you would use either the Commutative or Associative Property of Addition in a real world situation.

umka2103 [35]

So the best I could come up with is paper-rock-scissors; the operation takes two inputs and puts out the winner (assuming they are different).

So (paper rock) scissors= paper scissors = scissors,

But paper (rock scissors)= paper rock = paper.

This is a good example because it shows that associativity matters even outside of math.

A school conducts 27 tests in 36 weeks. Assume the school conducts tests at a constant rate. What is the slope of the line that

NeTakaya

Answer:

The slope of the line that represents the number of tests on the y-axis and the time in weeks on the x-axis is $\frac{3}{4}$ .

Step-by-step explanation:

<h3>Definition of slope of a line:</h3>

The slope of a line describes its steepness. In mathematical terms, for a line passing through two points with known coordinates, the slope is defined as the ratio of the change in the y-coordinates to the change in the x-coordinates.

<h3>Formula for the slope of a line:</h3>

Let 'm' represent the slope of a line passing through two points with coordinates $(x_{1},y_{1})$ and $(x_{2},y_{2})$ . So, according to the definition, the slope of the line can be written as follows,

$m=\left|\frac{y_{2}-y_{1} }{x_{2}-x_{1}}\right|$

<h3>Calculation of slope:</h3>

According to the information given in the question, the school conducts $27$ tests in $36$ weeks.

Now, any point on the $x-$ axis is given by the general form $(x,0)$ , where $x$ represents any numerical value on the axis. Similarly, any point on the $y-$ axis is given by the general form $(0,y)$ , where $y$ represents any numerical value on the axis.

It is given that the time in weeks is represented on the $x-$ axis, so $36$ weeks can be represented as coordinates as $(36,0)$ . Likewise, the number of tests conducted, i.e., $27$ can be represented as coordinates as $(0,27)$ .

Now, slope of the line passing through the above mentioned points, using the formula is as follows,

$m=\left| \frac{27-0}{0-36} \right|\\m=\left| \frac{27}{-36} \right|\\\\m=\left| \frac{3}{-4} \right|\\\\$

Simplifying the mod operator, the slope of the line is found to be $\frac{3}{4}$ .

Hence, the correct option is option $A. \frac{3}{4}$ .
