Answer:
v = -8
Step-by-step explanation:
First we would have to distribute the 8(-5 - 7v). To do this we would multiply 8 by -5 and 8 by -7v to get
. After this, we would have to simplify like terms by subtracting 56v from -5v to get
. We now have to get the variable on one side and to do that, we can add 40 to both sides to get
. Finally to get the variable alone, we would have to divide both sides by -61 to get
.

Step-by-step explanation:
Opposite angles of a cyclic quadrilateral are supplementary, so:

Answer:
0.999987
Step-by-step explanation:
Given that
The user is a legitimate one = E₁
The user is a fraudulent one = E₂
The same user originates calls from two metropolitan areas = A
Use Bay's Theorem to solve the problem
P(E₁) = 0.0131% = 0.000131
P(E₂) = 1 - P(E₁) = 0.999869
P(A/E₁) = 3% = 0.03
P(A/E₂) = 30% = 0.3
Given a randomly chosen user originates calls from two or more metropolitan, The probability that the user is fraudulent user is :




= 0.999986898 ≈ 0.999987
