Of all the people applying for a certain job 75% are qualified and 25% are not. The personnel manager claims that she approves q
Gwar [14]

Answer:

The probability is: 0.8889.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Approved

Event B: Qualified

Probability of a person being approved:

80% of 75%(qualified)

30% of 25%(not qualified). So

P(A) = 0.8*0.75 + 0.3*0.25 = 0.675

Probability of a person being approved and being qualified:

80% of 75%, so:

P(A \cap B) = 0.8*0.75

Find the probability that a person is qualified if he or she was approved by the manager.

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.8*0.75}{0.675} = 0.8889

The probability is: 0.8889.

The graph of f(x) = x6 – 2x4 – 5x2 + 6 is shown below.
DochEvi [55]

Answer:

There are two rational roots for f(x)

Step-by-step explanation:

We are given a function

f(x) = x^6-2x^4-5x^2+6

To find the number of rational roots for f(x).

Let us use remainder theorem that when

f(a) =0, (x-a) is a factor of f(x) or x=a is one solution.

Substitute 1 for x

f(1) = 1-2-5+6=0

Hence x=1 is one solution.

Let us try x=-1

f(-1) = 1-2-5+6 =0

So x =-1 is also a solution and x+1 is a factor

We can write f(x) by trial and error as

f(x) = (x-1)(x+1)(x^2-3)

We find that f(x) (x^2-3) factor gives two irrational solutions as

±√3.

Hence number of rational roots are 2.

THE TOTAL DISTANCE OF A TRIP IS 986 MILES AND EACH HOUR THEY WILL DRIVE 65 MILES. WRITE AN EQUATION TO REPRESENT THE NUMBER OF R
hodyreva [135]

Since X is any number of hours, finding the distance traveled would be represented as 65x. To find the remaining, you would need to subtract, so it'd look like this: 986-65x. The best thing to do with problems like these is to take it slowly, and highlight the important parts if possible!
