Answer:
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
Two angles are given as 30 and 40 degrees.
The third angle we could find by subtracting both angles from 180.
So, third angle would be =
As we can see, there is no side which is equal to each other.
Similarly, there is no angle which is similar to each other.
Hence the triangle is Scalene triangle. : Answer

Answer:
μ ≈ 2.33
σ ≈ 1.25
Step-by-step explanation:
Each person has equal probability of ⅓.
The mean is the expected value:
μ = E(X) = ∑ X P(X)
μ = (1) (⅓) + (2) (⅓) + (4) (⅓)
μ = ⁷/₃
The standard deviation is:
σ² = ∑ (X−μ)² P(X)
σ² = (1 − ⁷/₃)² (⅓) + (2 − ⁷/₃)² (⅓) + (4 − ⁷/₃)² (⅓)
σ² = ¹⁴/₉
σ ≈ 1.25
