Answer:
Proportion of the trees will have diameters between 2 and 6 inches = 0.8164
Step-by-step explanation:
Given -
Mean = 4
Standard deviation = 1.5
Let X be the diameter of tree
proportion of the trees will have diameters between 2 and 6 inches =
=
= Put [
]
=
=
= .9082 - .0918
= 0.8164
Given:
The equation is:
To find:
The graph of the line that contains ordered pairs that are solutions of the given equation.
Solution:
We need to find the graph of the given equation.
We have,
At , we get
So, the x-intercept of the given equation is at point (0,4).
At , we get
So, the y-intercept of the given equation is at point (4,0).
From the given graphs it is clear that the line in option C has x-intercept at point (0,4) and y-intercept at point (4,0).
Therefore, the correct option is C.
