Answer:
RSP~ZXY
Step-by-step explanation:
Start without thinking of the options. You could do process of elimination, and that's fine, but to learn this kind of problem it's better to think it all the way through. The problem says you have 112 books, and an indefinite number shelves, s, that each hold sixteen books. You need to fit 112 books into shelves, each with sixteen books. That comes down to 112÷s=16, which is the same as 16s=112.
Answer:
The slope of the line is 2.
Step-by-step explanation:
The data provided is as follows:
<em>x </em>: 0 1 2 3
<em>y</em> : 2 4 6 8
The formula to compute the slope of a line is:
![\text{Slope} &= \frac{ n \cdot \sum{XY} - \sum{X} \cdot \sum{Y}}{n \cdot \sum{X^2} - \left(\sum{X}\right)^2}](https://tex.z-dn.net/?f=%5Ctext%7BSlope%7D%20%26%3D%20%5Cfrac%7B%20n%20%5Ccdot%20%5Csum%7BXY%7D%20-%20%5Csum%7BX%7D%20%5Ccdot%20%5Csum%7BY%7D%7D%7Bn%20%5Ccdot%20%5Csum%7BX%5E2%7D%20-%20%5Cleft%28%5Csum%7BX%7D%5Cright%29%5E2%7D)
Compute the required values in Excel as shown below.
Compute the value of slope as follows:
![b &= \frac{ n \cdot \sum{XY} - \sum{X} \cdot \sum{Y}}{n \cdot \sum{X^2} - \left(\sum{X}\right)^2} \\\\= \frac{ 4 \cdot 40 - 6 \cdot 20 }{ 4 \cdot 14 - \left( 6 \right)^2} \\\\= 2\end{aligned}](https://tex.z-dn.net/?f=b%20%26%3D%20%5Cfrac%7B%20n%20%5Ccdot%20%5Csum%7BXY%7D%20-%20%5Csum%7BX%7D%20%5Ccdot%20%5Csum%7BY%7D%7D%7Bn%20%5Ccdot%20%5Csum%7BX%5E2%7D%20-%20%5Cleft%28%5Csum%7BX%7D%5Cright%29%5E2%7D%20%09%09%09%09%09%09%09%5C%5C%5C%5C%3D%20%5Cfrac%7B%204%20%5Ccdot%2040%20-%206%20%5Ccdot%2020%20%7D%7B%204%20%5Ccdot%2014%20-%20%5Cleft%28%206%20%5Cright%29%5E2%7D%20%5C%5C%5C%5C%3D%202%5Cend%7Baligned%7D)
Thus, the slope of the line is 2.
