Let event Aequalssubject is telling the truth and event Bequalspolygraph test indicates that the subject is lying. Use your own

pochemuha

Answer:

C is the right answer

Step-by-step explanation:

In this case we have the events

A: The subject is telling the truth.

B: The the polygraph indicates that the subject is lying

Recall that P(B|A) is defined as the probability that the event B occurs given that the event has already occurred, and is equals to P(B∩A)/P(A).

So, with the events we have defined, P(B|A) indicates the probability that the polygraph indicates lying given that the subject is actually telling the truth.

The most suitable answer is thus, C

What is the quotient?

Zepler [3.9K]

Answer:

= $\dfrac{1}{5^{9}}$

Step-by-step explanation:

When dividing values with exponents, we simply need to subtract the numerators exponent to the denominators exponent.

So we have:

$\dfrac{5^{-6}}{5^{3} }$

= $5^{-6 - 3}$

= $5^{-9}$

Now since we have a negative exponent, we can get the reciprocal of the value to make it positive.

= $\dfrac{1}{5^{9}}$

Answer:

The simplified form is $x\geq -99$ .

Step-by-step explanation:

Given : Expression $\frac{x}{3}\geq -33$

To find : The simplified expression ?

Solution :

Expression $\frac{x}{3}\geq -33$

Multiply 3 both side,

$\frac{x}{3}\times 3\geq -33\times 3$

$x\geq -99$

Therefore, the simplified form is $x\geq -99$ .
