Answer:

The correct option is D.

Step-by-step explanation:

R-values represents the correlation between two variables. R-values lie from -1 to 1.

If r=-1 or closed to -1, then it represents strong negative correlation.

If r=0 or closed to 0, then it represents no correlation.

If r=1 or closed to 1, then it represents strong positive correlation.

From the given option it is clear that the number 0.3 is nearest to 0. Therefore 0.3 represents the weakest correlation and the correct option is D.

Step-by-step explanation:

(3 - √5)(2 + 3√5)

= 3(2 + 3√5) - √5(2 + 3√5))

= 6 + 9√5 - 2√5 - 15

Find the average rate of change of the function defined by the following table. x y -2 -5 2 35 6 75 10 115

Pani-rosa [81]

By definition we have that the average rate of change of the function is:

$AVR = \frac{f(x2) - f(x1)}{x2 - x1}$

Evaluating the function for the complete interval we have that the AVR is given by:

$AVR = \frac{115 - (-5)}{10 - (-2)}$

Rewriting we have:

$AVR = \frac{115+5}{10+2}$

Simplifying the expression we have:

$AVR = \frac{120}{12}$

$AVR = 10$

Answer:

the average rate of change of the function defined by the table is:

$AVR = 10$
