pi = 3.14...
pi^2 = 9.86...
3^2 = 9
4^4 = 16
Pi is between sqrt(9) and sqrt(16).
The answer would be 8, you have to use the distance formula.
Step-by-step Answer:
One of the properties of a least-squares regression line (line of best fit) is that the line always passes through the point (xbar, ybar).
Assuming the given "line of best fit" is a least-squares line, then we are given
a slope m=1.885 passing through (x0,y0)=(3.448,12.318).
Applying the standard point-slope formula:
(y-y0) = m (x-x0)
we get
y-12.318 = 1.885(x-3.448)
Expand and simplify,
y=1.885x -1.885*3.448 + 12.318, or
y=1.885(x) + 5.81852
(numbers to be rounded as precision dictates).
2,356 students would say corn is their favorite because if 62 out of 100 loved corn and there are 3,800 students you can multiply 62 by 38 and get your answer.
