I'm assuming that x is part of the data set, and, with x, the mean equals 105. To find the value of x, you must add all the data values together to get 544+x (you still don't know what x equals). Then put 544+x over how many days values there are, including x (there are 6). You should have 544+x/6. Now, as this is how you would calculate the mean if you knew what x was equal to, you must set it equal to the mean, since you know what it is (105). You should now have 544+x/6 = 105. You have your equation set up--now you just have to solve it. I would multiply by 6 on both sides to get rid of the 6 on the left side. You would then have 544+x = 630. I would finally subtract 544 from both sides to get x = 86. Your final answer is x = 86.

Answer:
![\{-2,-1,1,2,4\}](https://tex.z-dn.net/?f=%5C%7B-2%2C-1%2C1%2C2%2C4%5C%7D)
Step-by-step explanation:
Given
The attached graph
Required
Determine the range of the graph
First, we list out the coordinate of each point on the graph:
The points are:
![\{(-4,-1),(-3,-2),(-2,2),(1,1),(2,4)\}](https://tex.z-dn.net/?f=%5C%7B%28-4%2C-1%29%2C%28-3%2C-2%29%2C%28-2%2C2%29%2C%281%2C1%29%2C%282%2C4%29%5C%7D)
A function has the form: (x,y)
Where
y = range:
From the coordinate points above,
![y = \{-1,-2,2,1,4\}](https://tex.z-dn.net/?f=y%20%3D%20%5C%7B-1%2C-2%2C2%2C1%2C4%5C%7D)
Order from least to greatest"
![y = \{-2,-1,1,2,4\}](https://tex.z-dn.net/?f=y%20%3D%20%5C%7B-2%2C-1%2C1%2C2%2C4%5C%7D)
Hence, the range are: ![\{-2,-1,1,2,4\}](https://tex.z-dn.net/?f=%5C%7B-2%2C-1%2C1%2C2%2C4%5C%7D)
Answer:
19
or 18![\frac{5}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B4%7D)
Step-by-step explanation:
First, add the whole numbers
3, 7, and 8
18
Add the fractions
+
=![\frac{5}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B4%7D)
IF YOU WANT SIMPLIFIED NUMBER DO THIS
=1![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
18+1
=19![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
