Answer:
![83^{\circ}](https://tex.z-dn.net/?f=83%5E%7B%5Ccirc%7D)
Step-by-step explanation:
Let
be the point that denotes the pier.
![m\angle B=58^{\circ}](https://tex.z-dn.net/?f=m%5Cangle%20B%3D58%5E%7B%5Ccirc%7D)
![m\angle A=39^{\circ}](https://tex.z-dn.net/?f=m%5Cangle%20A%3D39%5E%7B%5Ccirc%7D)
The angle between A and B is C
![m\angle A+m\angle B+m\angle C=180^{\circ}\\\Rightarrow m\angle C=180^{\circ}-(m\angle A+m\angle B)\\\Rightarrow m\angle C=180^{\circ}-(58^{\circ}+39^{\circ})\\\Rightarrow m\angle C=83^{\circ}](https://tex.z-dn.net/?f=m%5Cangle%20A%2Bm%5Cangle%20B%2Bm%5Cangle%20C%3D180%5E%7B%5Ccirc%7D%5C%5C%5CRightarrow%20m%5Cangle%20C%3D180%5E%7B%5Ccirc%7D-%28m%5Cangle%20A%2Bm%5Cangle%20B%29%5C%5C%5CRightarrow%20m%5Cangle%20C%3D180%5E%7B%5Ccirc%7D-%2858%5E%7B%5Ccirc%7D%2B39%5E%7B%5Ccirc%7D%29%5C%5C%5CRightarrow%20m%5Cangle%20C%3D83%5E%7B%5Ccirc%7D)

Answer:
n = 12
Step-by-step explanation:
27 = 15 + n
27 - 15 = n
12 = n
Answer:
Var(X)=1.6
Step-by-step explanation:
Formula for calculating the coefficient of variation for a probability generating function:
Var(X)= PX''(1) + PX'(1) - [PX'(1)]² ........... eq(1)
Now compute each individual term in the above formula.
PX'(z) = ![(10) (0.8) (0.8z + 0.2)^9](https://tex.z-dn.net/?f=%2810%29%20%280.8%29%20%280.8z%20%2B%200.2%29%5E9)
PX'(1) =
= 8
[PX'(1)]² = 64
PX''(z) = ![(9) (8) (0.8) (0.8z + 0.2)^8](https://tex.z-dn.net/?f=%289%29%20%288%29%20%280.8%29%20%280.8z%20%2B%200.2%29%5E8)
PX''(1) =
= 57.6
Substitute all terms back in eq(1)
Var(X)= 57.6 + 8 - 64
Var(X)= 1.6
