If the data point is at (3, 10.5) and the prediction equation is y = -6.1x + 12.5, what is the value of the residual for this data point?

Given:

The data point is (3,10.5).

The prediction equation is .

To find:

The value of the residual for this data point.

Step-by-step explanation:

The data point is (3,10.5). So, the actual value is 10.5 at .

Prediction equation is

Putting , we get

The formula for residual is:

Residual = Actual value - Expected value

Therefore, the residual for the given data point is 16.3.

i'm assuming it's looking for the missing length, which should be 4cm

hope this !

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4
