Which statement about the graph is true?
2 answers:
<h2>Answer:</h2>
The statement that is true about the graph is:
The graph does not show a proportional relationship because each point written as ratio gives a different value.
<h2>Step-by-step explanation:</h2>A graph is said to have a proportional relationship if it is a straight line passing through the origin.
i.e. a variable must be a constant multiple of the other variable.
i.e. y=kx
From the given graph we have a straight line that passes through (0,2) and (2,3)
Hence, the equation of line is:
Hence, the graph does not show a proportional relationship as the equation of the graph is not of the form y=kx
This means that
for some constant k.

Answer:
The required probability is 0.94
Step-by-step explanation:
Consider the provided information.
There are 400 refrigerators, of which 40 have defective compressors.
Therefore N = 400 and X = 40
The probability of defective compressors is:
It is given that If X is the number among 15 randomly selected refrigerators that have defective compressors,
That means n=15
Apply the probability density function.
We need to find P(X ≤ 3)
Hence, the required probability is 0.94
