Given:
The graph of a scatter plot.
To find:
The function that best fits the given points.
Solution:
From the given graph it is clear that the linear function is the best fit for the given points because the points lie on a straight line or near to it.
So, options B and C are incorrect because they represent exponential and quadratic function respectively.
Let as assume the two points on the graph are (0.80,-12.82) and (2,-12.79).
Using this two points, the equation of line is:
It is the approximate function to the function that is in option A.
Therefore, the correct option is A.
Answer:
Step-by-step explanation:
The circumference of circle of radius
is given by
,
and the diameter is 2 times the radius:
.
Therefore, the ratio of the circumference to the diameters is
.
Putting in , we get
