You can look at those dots, for example, you see (2,8) and (2,2) then look at y and the difference is 6. so if you see it like that, (2,8) and (5,8) is 3, (5,8) and (5,4) would be 4, (5,4) and (8,4) would be 3, (8,4) and (8,2) would be 2, and lastly (2,2) and (8,2) is 6
Now you add all of them up which will be 6+3+4+3+2+6 = 24
so the perimeter of this figure is 24<span />
Answer:
17
Step-by-step explanation:
A.) 0.55
This is because the probability has to com out to 1 (technically 100%) so, 1-0.45 is 0.55 (these could all be percentages if you multiply them by 100)
Plug in m/4 into the equation:
![8 (\frac{m}{4})^{2} - 4(\frac{m}{4})](https://tex.z-dn.net/?f=8%20%28%5Cfrac%7Bm%7D%7B4%7D%29%5E%7B2%7D%20-%204%28%5Cfrac%7Bm%7D%7B4%7D%29)
Solve the parentheses in the equation:
![\frac{m}{4}^{2} = \frac{m}{4} \times \frac{m}{4} = \frac{m^{2}}{16}](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7B4%7D%5E%7B2%7D%20%3D%20%5Cfrac%7Bm%7D%7B4%7D%20%5Ctimes%20%5Cfrac%7Bm%7D%7B4%7D%20%3D%20%5Cfrac%7Bm%5E%7B2%7D%7D%7B16%7D)
![8 \times \frac{m^{2}}{16} = \frac{8m^{2}}{16} = \frac{m^{2}}{2}](https://tex.z-dn.net/?f=8%20%5Ctimes%20%5Cfrac%7Bm%5E%7B2%7D%7D%7B16%7D%20%3D%20%5Cfrac%7B8m%5E%7B2%7D%7D%7B16%7D%20%3D%20%5Cfrac%7Bm%5E%7B2%7D%7D%7B2%7D%20)
![4 \times \frac{m}{4} = \frac{4m}{4} = m](https://tex.z-dn.net/?f=4%20%5Ctimes%20%5Cfrac%7Bm%7D%7B4%7D%20%3D%20%5Cfrac%7B4m%7D%7B4%7D%20%3D%20m)
Your equation should now look like this:
![\frac{m^{2}}{2} - m](https://tex.z-dn.net/?f=%5Cfrac%7Bm%5E%7B2%7D%7D%7B2%7D%20-%20m)
The answer is
D.
