Answer:
0.980
Step-by-step explanation:
The probability that the noise level of a wide-band amplifier will exceed 2 dB is 0.05
So, probability of success = 0.05
Probability of failure = 1-0.05=0.95
There are 12 amplifiers
We are supposed to find the probability that at most two will exceed 2dB.
We will use binomial distribution
Formula :
p = 0.05
q = 0.95
n = 12
We are supposed to find the probability that at most two will exceed 2dB.
So,
Hence the probability that at most two will exceed 2dB is 0.980
Answer:
Michael
Step-by-step explanation:
Look at the table below:
The probability of selecting a sale that was made by Quentin is .30, by Michael is .45 and by Bubba is .25.
Since Quentin completes paperwork 90% of the time, he doesn't complete paperwork 10% of the time, following this reasoning we can say that Michael doesn't complete paperwork 20% of the time and Bubba doesn't complete paperwork 15% of the time.
The probability of selecting a file and that it belongs to Quentin AND is incomplete is:
(Probability of selecting a Quentin's file) x (Probability is a Quentin incomplete file) = (0.30)(0.10) = 0.03
Using this same method we have that the probability that it belongs to Michael and is incomplete is (.45)(.20) = 0.09
That it belongs to Bubba and it's incomplete is (0.25)(0.15) = 0.037
The highest of these probabilities is the one that corresponds to Michael: 0.09, therefore he is the most likely culprit.
Answer:
Both amplitude and coefficient are equal.
Step-by-step explanation:
Given the equation y = 50 sinx. we have to find the relationship between the amplitude of y = 50 sinx and the coefficient 50.
For the curve y = a sin x, the variable 'a' represents the amplitude of graph i.e
Amplitude=|a|
Hence, for the curve y = 50 sinx
Amplitude=|a|=|50|=50
which is equal to the coefficient 50.
Hence, both amplitude and coefficient are equal.
