The 'mean' is most affected by adding a really small or large number to a data set. These big or small numbers are called 'outliers' in statistics :)

Answer:
240 cm²
Step-by-step explanation:
We are required to determine the surface area of the figure;
To get the area we add the are of all the surfaces;
Area of triangle;
Area = 0.5 × b × h
There are two triangles;
Therefore;
Area of the two triangles;
Area = 0.5 × 6 × 8 × 2
= 48 cm²
Area of the rectangles;
Area of a rectangle = Length × width
Area of the first rectangle;
= 6 cm × 8 cm
= 48 cm²
Area of the second rectangle
= 8 cm × 8 cm
= 64 cm²
Area of the third rectangle
= 10 cm × 8 cm
= 80 cm²
The total surface area will be;
Area = 48 cm² + 48 cm² + 64 cm² + 80 cm²
= 240 cm²
Answer:
i think x=1 y=3 (1,3)
Step-by-step explanation:
2x+4x-1 = 5
x = 1
y = 4x-1
y = 4(1)-1
y = 4-1
y = 3
Answer:
Area of the parallelogram= 
Step-by-step explanation:
Area of a parallelogram = Length * Perpendicular height
To find the perpendicular height of the parallelogram:
Using given angle 60° in the triangle.


Area of the Parallelogram:

Area of the parallelogram= 
C
The construction described creates the incenter of the circle and this point is equidistant from all vertices of a triangle.
