We have two triangles and the trapezoid.
The formula of an area of a triangle:
b - base
h - height
The formula of an area of a trapezoid:
b₁, b₂ - bases
h - height
Triangle 1:
b = 3, h = 2
Triangle 2:
b = 6, h = 1
Trapezoid:
b₁ = 7, b₂ = 9, h = 6
The area of the figure:
From the given discrete distribution, we have that:
- The mean of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.
- The variance is given by the sum of the difference squared between each observation and the mean, divided by the number of values.
- The standard deviation is the square root of the variance.
In this problem, the distribution is:
Hence, the mean is:
The variance is:
The standard deviation is:
