Vikentia [17]

Answer:

No, Justin is incorrect.

Step-by-step explanation:

1. To find how much 18/40 as a percent is, we just multiply 18/40 by 100:

$\frac{18}{40} * 100$
$\frac{9}{20} * 100$
$\frac{900}{20}$
$45$

2. As you can see, 18/40 as a percent is 45%, not 35%. Therefore, Justin is incorrect.

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:

$AVR = 10$
