The correct answer is d=45 :)
Answer:
1.25 * N
Step-by-step explanation:
We have to increase N by 25%.
The first thing is to say how the percentage works in these cases, N would be our 100% and the increase would be 25% in this case, therefore, the initial value must be added (that is, N, 100%) and to that if add 25% of the initial value (that is, + 25% N).
Thus:
100% * N + 25% * N = N * (100% + 25%)
N * (125%) = 1.25 * N
So to increase N is 25% it would be 1.25 * N
Expenses of respondents in a survey is a quantitative data and the level of measurement is a ratio scale.
<h3>What is a Qualitative and a Quantitative Data?</h3>
A quantitative data can be described as a type of data that you can measure or counted, and also given a numerical value to, while a qualitative data is a type of data that cannot be expressed using numbers.
Examples of quantitative data include, number of students in a class, weight of students in a class, etc.
Examples of qualitative data include hair color, religion, nationality, etc.
Expenses of respondents can be given numerical values, therefore, expenses of respondents in a survey is a quantitative data and the level of measurement is a ratio scale.

Answer:
Step 1:
To find ordered pair solutions, you could create an x and y graph and fill out the x side. Then, plug in an x number to get your y number and graph the ordered pairs to see if they give you a straight line. I'm going to use these numbers: -1, 0, 1, and 2.
![\left[\begin{array}{ccc}-1&?\\0&?\\1&?\\2&?\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-1%26%3F%5C%5C0%26%3F%5C%5C1%26%3F%5C%5C2%26%3F%5Cend%7Barray%7D%5Cright%5D)
Now, let's plug in -1 into the equation first to see what we get for y.
-5 is our y if x was -1.
We do the same for the other three numbers.
Step 2:
With all that done, we can now fill out our table and graph the points.
![\left[\begin{array}{ccc}-1&-5\\0&3\\1&11\\2&19\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-1%26-5%5C%5C0%263%5C%5C1%2611%5C%5C2%2619%5Cend%7Barray%7D%5Cright%5D)
If you graph these points on graph paper / a graphing website, you will see that these points go in a straight line. If you are given an ordered pair already (for example: (3,5)), then all you have to do is plug in the x into the equation (3) and see if the outcome is true (5).
Since they don't equal each other, then (3,5) is false.
Here is the graph for the table above. I hope I helped you!
