Answer:
1. The probability that x will be more than 25 is 0.6305.
2. The 55th percentile is 26.38.
Step-by-step explanation:
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation
, the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean 26 and standard deviation 3.
This means that
1 Find the probability that x will be more than 25.
This is 1 subtracted by the p-value of Z when X = 25. So
has a p-value of 0.3695.
1 - 0.3695 = 0.6305.
The probability that x will be more than 25 is 0.6305.
2 Find the 55th percentile of x.
This is X when Z has a p-value of 0.55, so X when Z = 0.125.
The 55th percentile is 26.38.
Given
You created a new playlist in 100 of your friends listened to it and shared if they liked
The new playlist said the ratio Of people who liked the playlist to those who did not like the playlist is 75:25.
Dylan said that for every three people who like to playlist one person did not
Find out Do Nadhii and Dylan Agree or not.
To proof
As given in the question
created a new playlist in 100 of your friends listened to it and shared if they liked
new playlist said the ratio Of people who liked the playlist to those who did not like the playlist is 75:25.
Simply the ratio of people who liked the playlist to those who did not like the playlist
Thus
also
Dylan said that for every three people who like to playlist one person did not
In the form of ratio written as
the value of both new playlist and Dylan said about the ratio of people who liked the playlist to those who did not like the playlist is 3:1.
The value both of their ratio are equivalent .
Thus Nadhii and Dylan Agree
Hence proved
Answer:
V ≈ 16.333 in³
Step-by-step explanation:
Formula of the Volume of a Sphere:
V = × (3.5)²π
V = × 12.25π
V ≈ 16.333 in³
