Answer:
Third quadrant
Step-by-step explanation:
Look at the attached image. All the points are in the third quadrant.
The solution to the equation one-third (x + 9) = negative 12 is x = -45
<h3>How to solve the equation?</h3>
The equation is given as:
one-third (x + 9) = negative 12
Rewrite properly as:
1/3 (x + 9) = -12
Multiply both sides by 3
x + 9 = -36
Subtract 9 from both sides
x = -45
Hence, the solution to the equation one-third (x + 9) = negative 12 is x = -45

Step-by-step explanation:
Mean is the average number. To find mean, add all the numbers and divide by how many numbers there are.
![78 + 82 + 91 + 100 + 78 + 92 + 82 + 77 + 80 = 760](https://tex.z-dn.net/?f=%2078%20%2B%2082%20%2B%2091%20%2B%20100%20%2B%2078%20%2B%2092%20%2B%2082%20%2B%2077%20%2B%2080%20%3D%20760%20)
There are 9 numbers. Divide by 9
![760 \div 9 = 84.44](https://tex.z-dn.net/?f=%20760%20%5Cdiv%209%20%20%3D%2084.44%20)
Question 6 ⇒ C. 84.44
Median is the middle number when ordered from least to greatest. First order the numbers.
![4, 5, 6, 9, 10, 11, 12, 13, 15, 16](https://tex.z-dn.net/?f=%204%2C%205%2C%206%2C%209%2C%2010%2C%2011%2C%2012%2C%2013%2C%2015%2C%2016%20)
The 2 middle numbers are 10 and 11. Add them together and divide by 2
![10 + 11 = 21 \\ 21 \div 2 = 10.5](https://tex.z-dn.net/?f=%2010%20%2B%2011%20%3D%2021%20%5C%5C%2021%20%5Cdiv%202%20%20%3D%2010.5%20)
