The answer is 9.5% by simply diving 2000/210
Domain: Anything at all. All numbers and sub-divisions of a number line. - ∞ < x < ∞
The range is much harder. You could complete the square to get the range, which I will do after we get the answer. The simplest way to get the smallest part of the range is to graph the quadratic. The lowest point is at (-2, -25) so the range is
Range: -25 ≤ y < ∞
Completing the square.
y = x^2 + 4x - 21
y = (x^2 + 4x) - 21
y = (x^2 + 4x + (4/2)^2 ) - 21 - (4/2)^2
y = (x^2 + 4x + 4) - 21 - 4
y = (x + 2)^2 - 25
The minimum point is (- 2,-25) just as the graph predicted.
Answer:
42.7%
Step-by-step explanation:
Correlation is a statistical measure of inter relationship between two variables' co movement.
Correlation coefficient denotes the direction & extent by which two variables' (same or opposite) movement is linked to each other.
Coefficient of determination = r^2 symbolises percentage of variation in one variable, that can be explained by variation in other variable.
So, in this case r^2 = (0.654)^2 = 0.427716 ; Hence approx 42.7% variation in one variable can be explained by variation in other.
