A, 39
You can get the average score by adding up all the total scores, (33, 41, 33, 45 and 43) and dividing that by the total number of scores, 5. 195 (total score)/5 (number of scores)= 39.
Given:
The length of the lot l= 750ft
The width of the plot w= 540 ft
Required:
Find the required fence.
Explanation:
The perimeter of the rectangle is given by the formula.
![P=2(length+width)](https://tex.z-dn.net/?f=P%3D2%28length%2Bwidth%29)
Thus the required fence for the lot
![\begin{gathered} =2(750+540) \\ =2(1290) \\ =2580\text{ ft} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%3D2%28750%2B540%29%20%5C%5C%20%3D2%281290%29%20%5C%5C%20%3D2580%5Ctext%7B%20ft%7D%20%5Cend%7Bgathered%7D)
Final answer:
The required fence is 2580 ft.
The slope of the line that contains the point (13,-2) and (3,-2) is 0
<em><u>Solution:</u></em>
Given that we have to find the slope of the line
The line contains the point (13,-2) and (3,-2)
<em><u>The slope of line is given as:</u></em>
![m = \frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Where, "m" is the slope of line
Here given points are (13,-2) and (3,-2)
![(x_1, y_1) = (13, -2)\\\\(x_2, y_2) = (3, -2)](https://tex.z-dn.net/?f=%28x_1%2C%20y_1%29%20%3D%20%2813%2C%20-2%29%5C%5C%5C%5C%28x_2%2C%20y_2%29%20%3D%20%283%2C%20-2%29)
<em><u>Substituting the values in formula, we get,</u></em>
![m = \frac{-2-(-2)}{3-13}\\\\m = \frac{-2+2}{3-13}\\\\m = 0](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B-2-%28-2%29%7D%7B3-13%7D%5C%5C%5C%5Cm%20%3D%20%5Cfrac%7B-2%2B2%7D%7B3-13%7D%5C%5C%5C%5Cm%20%3D%200)
Thus the slope of line is 0
