The answer to your question is 90 dB
Step-by-step explanation:
Data
I = 10⁻³
I⁰ = 10⁻¹²
Formula
Loudness = 10log (
)
Process
1.- To solve this problem, just substitute the values in the equation and do the operations.
2.- Substitution
Loudness = 10 log 
3.- Simplify
Loudness = 10log (1 x 10⁹)
Loudness = 10(9)
Loudness = 90
Answer:
0.28 = 28% probability that a randomly selected driver will come to complete stop
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
Recording of 75 drivers.
Of those, 21 came to a complete stop.
Then
21/75 = 0.28
0.28 = 28% probability that a randomly selected driver will come to complete stop
