Answer:
0.002991
Step-by-step explanation:
Let
User is legitimate one = E₁
User is fraudulent one = E₂
User originates calls from two metropolitan = A
Therefore, according to the question
P(E₁) = 1 - 0.01% = 1 - 0.0001 = 0.9999
P(E₂) = 0.0001
P(A/E₁) = 1% = 0.01
P(A/E₂) = 30% = 0.30
Now,
P(E₂/A) = 
or
P(E₂/A) = 
or
P(E₂/A) = 0.002991
Formula- A = π r²
a= area
r= radius
diameter of the circle- 3.75 x 2 = 7.5
hope this helps :)
Which statement about solving inequalities is true?
Solving Inequalities Involving Multiplication
Let's start with the true statement:10 > 5
Next, multiply both sides by the same positive number:
10 • 2 > 5 • 2
20 is greater than 10, so you still have a true inequality:
20 > 10
When you multiply by a positive number, leave the inequality sign as it is!
Answer:
Step-by-step explanation:
1st expression: x⁴-y⁴
= (x²)² - (y²)²
= (x² +y²)(x² -y²)
= (x² +y²)(x +y)(x -y)
= (x +y)(x -y)(x² +y²)
2nd expression: x² -y²
= (x +y)(x -y)
3rd expression: x³ -y³
= (x -y)(x² +xy +y²)
Now ,
Lowest Common Multiples (L.C.M.) = common factors * rest factors
= (x+y)(x-y) * (x² +y²)(x² +xy +y²)
= (x² -y²)(x²+y²) * (x² +xy +y²)
= (x⁴ -y⁴)(x² +xy +y²)
