Identify the explanatory variable and the response variable. a farmer wants to determine if the amount of precipitation received by similar crops can be used to predict the harvest of the crop.

Response Variable:  harvest of crop

Explanatory Variable: Amount of precipitation

Step-by-step explanation:

Consider an equation,

y = a + bx₁ + cx₂

Here x₁ and x₂ are an explanatory variable

and, y is response variable

Explanatory Variable is a variable that is independent. It is also known as Independent Variable.

Response Variable is a variable that depends on an explanatory variable, hence change in the value of explanatory variable changes the value of Response Variable. It is also known as Dependent Variable.

As the value of the variable harvest of the crop depends on the amount of precipitation.

So, Here harvest of crop is Response Variable

and, Amount of precipitation is Explanatory Variable.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

answer is because 4×10=40

and 98×4= is 392

40,392
