The domain of a quadratic function in standard form is always all real numbers, meaning you can substitute any real number for x. The range of a function is the set of all real values of y that you can get by plugging real numbers into x.

C=2pie r solve for r

S_A_V [24]

Answer:

r = C / (2pie)

Step-by-step explanation:

C = 2pie x r

divide both sides by 2pie to isolate r

C / (2pie) = r

r = C / (2pie)

If a given data point is (1,4) and the line of best fit is y = 1.5x + 3.25, what's the residual value?

Svetlanka [38]

Answer:

The residual value is -0.75

Step-by-step explanation:

we know that

The residual value is the observed value minus the predicted value.

RESIDUAL VALUE=[OBSERVED VALUE-PREDICTED VALUE]

where

Predicted value.--> the predicted value given the current regression equation

Observed value. --> The observed value for the dependent variable.

in this problem

we have the point (1,4)

The observed value is 4

<em>Find the predicted value for x=1 </em>

$y =1.5(1)+3.25=4.75$

predicted value is 4.75

RESIDUAL VALUE=(4-4.75)=-0.75
