5. Which function would have the point (0,0) on its graph?
1 answer:
Answer:
B. <em>Output = Input x 5</em>
Step-by-step explanation:
Given:
Point (0,0)
To find which of the functions given will have the point (0,0) on its graph.
Solution:
In order to check whether a point lies on the graph of the function, we plugin the
as the input in the function and
as the output of the function and see if it satisfies the equation.
Plugging in point (0,0) in the functions given:
A. <em>Output = Input + 3</em>
Plugging in Output=0 and Input=0
The above statement can never be true and hence, the function graph does not have the point (0,0).
B. <em>Output = Input x 5</em>
Plugging in Output=0 and Input=0
The above statement is always true and hence, the function graph does have the point (0,0).
C. <em>Output = Input - 2</em>
Plugging in Output=0 and Input=0
The above statement can never be true and hence, the function graph does not have the point (0,0).
D. <em>Output = Input + 3</em>
Plugging in Output=0 and Input=0
The above statement can never be true and hence, the function graph does not have the point (0,0).

Answer:
For this case if we want to conclude that the sample does not come from a normally distributed population we need to satisfy the condition that the sample size would be large enough in order to use the central limit theoream and approximate the sample mean with the following distribution:
For this case the condition required in order to consider a sample size large is that n>30, then the best solution would be:
n>= 30
