Step-by-step explanation:
The mean absolute deviation is:
MAD = ∑ᵢ₌₁ⁿ│xᵢ − μ│/ n
First, find the mean.
μ = (x + 2x + 3x + 4x) / 4
μ = 2.5x
Now find the mean absolute deviation:
MAD = (│x − 2.5x│+│2x − 2.5x│+│3x − 2.5x│+│4x − 2.5x│) / 4
MAD = (│-1.5x│+│-0.5x│+│0.5x│+│1.5x│) / 4
MAD = (1.5x + 0.5x + 0.5x + 1.5x) / 4
MAD = (4x) / 4
MAD = x
Answer:
The perimeter of the figure as a function of the number of triangles is 
.
Step-by-step explanation:
According to the diagram, we get the following facts:
i) For one triangle (
), the total perimeter is (
).
ii) For two triangles (
), the total perimeter is (
)
iii) For three triangles (
), the total perimeter is (
)
iv) For four triangles (
), the total perimeter is (
)
From these information we conclude that the equation that determines the perimeter of the figure as a function of the number of triangles is .
Hello Missjay12,
Step 1 :
From the coordinates we have to find the slopes and midpoints of the lines.
Step 2 :
Find the slope of the bisectors and now find the equations of two lines by using slope and one mid points.
Step 3 :
Solve any two pair of equations and find the intersection point.
Step 4 :
The point thus found is the circumcenter of the given triangle.
so<span> the coordinates of the circumcenter of a triangle with vertices A(−3, 3) , B(−1, 3) , and C(−1, −1)</span> is, -4, 0.
