x*2 +8x+12
Step-by-step explanation:
The mean absolute deviation of the following set of data is 4.5
Step-by-step explanation:
We need to find the mean absolute deviation of the following set of data.
10,20,12,4,18,8,14,18
For finding mean absolute deviation, first we need to find the mean of the given data set.
The formula used to calculate mean is:
Sum of all data points: 10+20+12+4+18+8+14+18 = 104
Number of data points = 8
So, mean is:
Now, we will subtract 13 from the given data points:
10 - 13 = -3
20 - 13 = 7
12 - 13 = -1
4 - 13 = -9
18 -13 = 5
8 - 13 = -5
14 - 13 = 1
18 - 13 = 5
We will take absolute values i.e |-a|=a
So, now the numbers will be:
3,7,1,9,5,5,1,5
We will now find absolute mean deviation by finding mean of newly calculate values
Sum of all data points = 3+7+1+9+5+5+1+5
Number of data points = 8
So, the mean absolute deviation of the following set of data is 4.5
An equation is formed of two equal expressions. The solution of the system of equations is (0.75, 1.25).
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution to the system of equation is,
y = 2 - x
y = 3x - 1
Substitute the value of y,
y = y
2 - x = 3x - 1
2 + 1 = 3x + x
3 = 4x
x = 3/4 = 0.75
Substitute the value of x in any one of the equation,
y = 2 - x
y = 2 - 0.75
y = 1.25
Hence, the solution of the system of equations is (0.75, 1.25).

Answer:
D
Step-by-step explanation:
I'm assuming you're looking for area here.
The formula is b * h = A
So all you're doing is multiplying 30 by 18 to get 540.
