Answer:

For this case we define the dependent variable as Y and the independent variable X. We assume that we have n observations and that means the following pairs:

(x_1, y_1) ,....,(x_n,y_n)

For this case we assume that we want to find a linear regression model given by:

\hat y = \hat m x +\hat b

Where:

\hat m represent the estimated slope for the model

\hat b represent the estimated intercept for the model

And for any estimation of the dependent variable \hat y_i , i=1,...,n is given by this model.

The difference between the observed value of the dependnet variable and the value predicted using the estimated regression equation is known as residual, and the residual is given by this formula:

e_i = y_i -\hat y_i , i=1,...,n

So the best option for this case is:

d. residual

John is driving around town. When he reaches the gas station, he notes that he has traveled 20 miles. He reaches home 2 hours la
Troyanec [42]

Answer:

d=5t+20

Step-by-step explanation:

The equation that will model this situation will be of the form

d=mt+b

where t is the time in hours john has traveled since the gas station, and  d is the distance.

Now we know that John has already traveled 20 miles when he is at the gas station, this means at t=0, d=20; or

20=m(0)+b

\boxed{b=20}

Thus we have

d=mt+20.

Now we need to figure out m.

When John reaches home 2 hours later he notes that he has traveled 30 miles, which means he has traveled 30 - 20 = 10 miles; thus we have

m= \frac{\Delta d}{\Delta t} =\frac{10 miles}{2hours} =5

\boxed{m=5}

Now we have the full equation:

\boxed{d=5t+20}
