What does a residual value of –4.5 mean in reference to the line of best fit?
Step2247 [10]

Answer:

The residual value is the difference between the observed value (from the scatter plot) and the predicted value (from the line of best fit).


Step-by-step explanation:

The residual value is the difference between the observed value (from the scatter plot) and the predicted value (from the line of best fit).

Residual Value = Observed Value - Predicted Value

<em>Since the residual value of -4.5 is negative, we can say the predicted value is larger than the observed value. In other words, the line of best fit is "above" the scatter plot point in that specific point.</em>

Answer:

The measure of angle DPA is 39°

Step-by-step explanation:

step 1

Find the value of x  we know that  arc AB+arc BC+arc CD+arc DA=360°

substitute the values

(5x+10)°+(x+1)°+3x°+(3x+25)°=360°

Solve for x

(12x+36)°=360°

12x=360°-36°

x=324°/12=27°

step 2  Find the measure of angle DPA

we know that  The measurement of the external angle is the semi-difference of the arcs which comprises

m∠DPA=(1/2)[arc DA-arc BC]

arc DA=3(27)+25=106°

arc BC=27+1=28°

substitute the values

m∠DPA=(1/2)[106°-28°]=39°
