Question

jace gathered the data in the table. he found the approximate line of best fit to be y = -0.7x + 2.36. what is the residual value when x = 5? -3.14 -0.86 0.86 3.14 x y 0 3 1 1 4 0 5 -2 7 -2

Explanation:

Step1: Calcular el valor predicho

Sustituir \(x = 5\) en \(y=-0.7x + 2.36\).
\(y=-0.7\times5 + 2.36=-3.5+2.36=-1.14\)

Step2: Calcular el residual

El residual se define como valor real - valor predicho. El valor real de \(y\) cuando \(x = 5\) es \(- 2\).
Residual \(=-2-(-1.14)=-2 + 1.14=-0.86\)

Answer:

-0.86
