Answer:
y=1.8x-9
Step-by-step explanation:
if they are intercepts so the x/y will be zero, so in y intetceot the x is zero, and in the x itercept the y is zero.
0,-9
5,0
we calculate the slooe / rise
-9-0/0-5 = 1.8
we then use this formula
y-y1=rise(x-x1)
y-0=1.8(x-5)
y=1.8x-9
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

Answer:
x = 12
Step-by-step explanation:
The square of the length of the tangent segment is equal to the product of lengths from the external common point to the two circle intersections of the secant.
x^2 = (2)(70+2)
x^2 = 144
x = √144
x = 12

We have the vertex (-4, -1), therefore we have:
