Answer:

70 joules

Step-by-step explanation:

We have the following information

100N and 0.7 m

What is workdone?

We say that Work is done if a force which is applied to an object is able to move that object. We calculate the value of The work by multiplying the force by what is known to be the movement of the object.

(Workdone = Force x distance).

A force of 100 newtons, in this question moves an object 0.7 meters

Workdone =

100N x 0.7

= 70 joules

Thank you!

Write the simple linear regression equation for miles per gallon as the response variable and weight as the predictor variable.
horsena [70]

The simple linear regression equation for miles per gallon as the response variable and weight as the predictor variable is

M = \beta0 + \beta1W + ε

The car rental company can use this model to determine the effect of weight (of the car) on miles per gallon.

Given: To write a simple linear regression equation with Miles per gallon as the response variable and weight as the predictor variable.

What is simple linear regression?

Simple linear regression is used to estimate the relationship between two quantitative variables.

Let's say "Miles per gallon" is represented as M and

"Weight" be represented as W

The simple linear regression equation is :

M = \beta0 + \beta1W + ε

where,

  • M is Miles per gallon, the response variable also known as the dependent variable shows a predicted value for any given value of the independent variable W.
  • \beta0 is the intercept, the predicted value of M when W is 0
  • \beta1 is the regression coefficient -  how much we expect M to change as W increases.
  • W is the predictor variable also known as the independent variable ( the variable that is influencing M )
  • ε is the error of the estimate, or how much variation there is in our estimate of the regression coefficient.

How might the car rental company use this model?

The car rental company might use the regression model to determine the

  • Effect of weight (of car) on miles run per gallon
