Step-by-step explanation:
Answer:
Step-by-step explanation:
This is a question from conditional probability.
We are given:
And, we need to find P(A | B)
According to the formula of conditional probability:
Using the values, we get:
Thus, the probability of occurrence of event A given that event B has already occurred is
Answer:
The sound in a loud part of the room is 10000 times louder than sound in a quiet part of the same place.
Step-by-step explanation:
The acoustic intensity sound is a logarithmic function whose form is:
Where:
- Acoustic intensity sound, measured in decibels.
- Reference sound intensity, measured in watts per square meter.
- Real sound intensity, measured in watts per square meter.
Sound intensity is now cleared:
The ratio of the sound intensity in a loud part to the sound intensity in a quiet part is:
The sound in a loud part of the room is 10000 times louder than sound in a quiet part of the same place.

Answer: Line 1 should be x = y² + 12y NOT (x = y² + 12 x)</h2>
<h3>
Step-by-step explanation:</h3>
solving for the inverse of y = x² + 12x
Line 1: x = y² + 12 x.
Line 2 y² = x - 12 x. <em> </em>
Line 3 is y²= - 11 x.
Line 4 is y = √(- 11x) for x ≥ 0.
The error lies in Line 1. All x's have to be switched with y's and vice versa for the method to work.
As such Line 1 should be x = y² + 12y NOT (x = y² + 12 x)
Since Line one is wrong, it messes with all the other lines.
- f(8) replaces x, so replace all values of x within the equation with 8
- f(8) = 1/2^2 - (1/4(8)+3))
- f(8) = 1/2^2 - (5)
- f(8) = .25 - 5
- f(8) = -4.75 (or -4 3/4)
