ipn [44]

Answer:

90.91% probability that a car needs an oil change given that it has a certain factory defect

Step-by-step explanation:

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 problem, we have that:

Event A: having a factory defect.

Event B: needing an oil change.

The probability that a car has a certain factory defect is 825.

So $P(A) = 0.825$

The probability that a car has a certain factory defect and needs an oil change is 750.

So $P(A \cap B) = 0.75$

What is the probability that a car needs an oil change given that it has a certain factory defect

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.75}{0.825} = 0.9091$

90.91% probability that a car needs an oil change given that it has a certain factory defect

Which number is an irrational number

allochka39001 [22]

Hi there! The answer is C.

An irrational number is a number that cannot be written as a fraction.

A, B and D can be written as a fraction.
A. 3.5 = 3 1 / 2
B. square root of 36 = 6 = 6 / 1
D. 37 / 100 is already a fraction.

Hence, the only number that cannot be written as a fraction is the square root of 48.

$\sqrt{48} = 6.928...$

The answer is C: the square root of 48 is an irrational number.

If sin(x) = 3/5, what is sin(2x)

scZoUnD [109]

<h3>Answer: 24/25</h3>

====================================================

Explanation:

If sin(x) = 3/5, then cos(x) = 4/5 through the use of the trig identity

sin^2(x) + cos^2(x) = 1

This is assuming that x is in quadrant Q1.

Plug those values into the identity below and simplify.

sin(2x) = 2*sin(x)*cos(x)

sin(2x) = 2*(3/5)*(4/5)

sin(2x) = 24/25
