The sound intensity of rustling leaves, y = 20 decibels
<u>Step-by-step explanation:</u>
y = 10logx
The sound intensity of rustling leaves is 100 times the reference intensity.
x = ratio of intensity of sound to reference to intensity
x = 100:1 or x = 100
y = 10 log(100) = 10 * 2 = 20 decibels
y = 20 decibels
Answer:
the probability is 0.6293
Step-by-step explanation:
The computation of the probability is shown below:
Given that
n = 5
P = 0.18
As it represents the binomial distribution
P(X = x) =
× p^x × (1 - p) ^(n - x)
P(X > 1) = 1 - P(X < 1)
= 1 - P(X = 0)
= 1 - (
× (0.18) ^0 × (0.82) ^5)
= 1 - 0.3707
= 0.6293
hence, the probability is 0.6293
Hello!
The graphs of sine and cosine are waves. Therefore, choice A and B are wrong.
The graph of f(x) = cot(x) is an inverse of f(x) = tan(x), so therefore the graph of f(x) = cot(x) has the lines similar to the graph above, but it's flipped.
So therefore, the graph shown above is choice C, f(x) = tan x.
Answer:
The correct answer is C! :)
Step-by-step explanation:
It's is A -11/9 hope this helps
