Answer:
Option (4)
Step-by-step explanation:
Table for the points from the graph attached,
x y xy
2.2 1.8 4.84 3.24 3.96
3.2 1.8 10.24 3.24 5.76
3.6 3 12.96 9 10.8
4.8 3.5 23.04 12.25 16.8
5.2 6.2 27.04 38.44 32.24
6.4 4.5 40.96 20.25 28.8
7.5 7.8 56.25 60.84 58.5
8.5 6.2 72.25 38.44 52.7
n = 8
Formula for the correlation coefficient
r =
r =
r =
r = 0.87
r ≈ 0.9
Therefore, Option (4) is the answer.
400 I think I am not sure tho hope this helps
Divide each term in the y column by 2 to go from this list {8, 2, 0, 2, 8} to this list {4, 1, 0, 1, 4}
This list {4, 1, 0, 1, 4} is a bunch of perfect squares so it suggests that y = x^2
However we must double the values to get back to the original list. So the rule is y = 2*x^2
The domain of the function is all real numbers because it is a quadratic equation
