Identify the explanatory variable and the response variableA golfer wants to determine if the amount of practice every year can be used to predict the amount of improvement in his game.The explanatory variable is the The response variable is the

the explanatory variable is "the amount of practice every year" while the response variable is "the improvement in his game"

Step-by-step explanation:

In simple terms, the difference between explanatory and random variable is that the response variable is usually the focus of a question in a study/experiment while an explanatory variable is a variable that explains changes in the response variable. Which means that the explanatory variable is simply any variable that may affect the response variable.

Now, in this question, the golfer wants to determine if the amount of practice every year can be used to predict the amount of improvement in his game.

This means that the amount of practice every year explains how much he improves every year.

Thus, the explanatory variable is "the amount of practice every year" while the response variable is "improvement in his game"

This can be solved with an equation.

 

now, as far as I can tell this question was made multiple choice for a reason; just start to plug in numbers. So using the answers x is either equal to 1 or 2. lets try and solve the equation plugging 2 in. When you solve for this you end up with  none of your answers have one where y<2 so x must be 1. so lets solve for x=1.
you end up getting 

The only answer where x=1 and y<4 is C sos c is your answer. Hope this helped! :)
