Kevin recorded the effects of violent video games on antisocial behavior.

den301095 [7]

Answer:

Explanation:

Because the study is relying on the effects of violent video games and how it affects anti-social behavior.

If this was a math problem it'd be:

---> y= effect and signs of anti social behavior.

---> x= violent video games.

--->5= Hours spent playing. (Lets use 5 as a random number to write this as an equation then.)

Equation form:

Most likely would look something like this

(5x=y)

Hope this helped. I know it's late but it came up on my "Selected for you" section so I decided I'd answer it.

It takes three identical water pumps 8 hours to fill a pool, What is the constant of variation?

BaLLatris [955]

Answer:

Constant of variation is 24.

Step-by-step explanation:

Inverse variation states that a relationship between two variables in which the product is remain constant.

If one variable increases then, the other one decreases in proportion so that the product is unchanged,

if y is inversely proportional to x i.e $y \propto\frac{1}{x}$ or

$y =\frac{k}{x}$ ;where k is the constant of variation.

It is given that 3 identical water pumps takes 8 hours to fill a pool,

since, it will take less time with more pumps, so it is an inverse variation.

By definition of inverse variation;

$time = \frac{k}{pump}$

Substitute the values to solve for k;

$8 = \frac{k}{3}$

Multiply by 3 to both sides we get;

$8 \times 3 = \frac{k}{3} \times 3$

Simplify:

k = 24

Therefore, the constant of variation is, 24
