Roger's method would not provide relevant results for what he was trying to accomplish because he was calculating average over a 3 month period instead of for a single day.
<h3>How to find the mean temperature?</h3>
Mean/Average of any given data simply means the sum of the given data divided by the sample size of the given data.
Now, when talking about average temperature, it simply means adding the temperatures for the duration you intend to analyze and then dividing the sum by the number of temperatures you added.
However, in this question Roger wants to find the average temperature for any given data and we know the temperatures in a 24-hour day may differ from time to time and as such the mean/average for a particular day would simply be found by adding up temperatures for the day and then dividing by the number of temperatures added.
Thus, Roger's method would not provide relevant results for what he was trying to accomplish because he was calculating average over a 3 month period instead of for a single day.

so you read 12 + 13 = 25 books in total, and 12 nonfiction ones.
if we take 25 to be the 100%, what is 12 off of it in percentage?
![\bf \begin{array}{ccll}amount&\%\\\cline{1-2}25&100\\12&x\end{array}\implies \cfrac{25}{12}=\cfrac{100}{x}\implies x=\cfrac{12\cdot 100}{25}\implies x=48](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccll%7Damount%26%5C%25%5C%5C%5Ccline%7B1-2%7D25%26100%5C%5C12%26x%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B25%7D%7B12%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%5Cimplies%20x%3D%5Ccfrac%7B12%5Ccdot%20100%7D%7B25%7D%5Cimplies%20x%3D48)
Step-by-step explanation:
Let us consider the length of a line segment to be 'x'
Let the other line segment be 'y'
One line segment is 12 less than twice the length of other segment.
X = 2y - 12
The sum of both the lengths = 69cm
X + Y = 69
X = 69 - Y
Substitute the X value in the first equation
X = 2y - 12
69 - Y = 2Y - 12
- Y - 2Y = -12 -69
- 3Y = - 81
3Y = 81
Y = 81/3
Y = 27 CM
Length of One of the line segment is 27cm
The length of the other line segment 'x'
is
X= 2y - 12
X = 2(27) - 12
X = 54 - 12
X = 42cm
The length of the line segments are 42cm and 27cm.
