a line of best fit is drawn for the set of points shown on the graph. which point is an approximate extrapolation for x = 30 from the line of best fit? (23, 30) (30, 38) (44, 30) (30, 72)
Answer
Explanation:
Step1: Identificar la ecuación de la recta de mejor ajuste
La ecuación de la recta de mejor ajuste es $y = 1.24x+3.805$.
Step2: Sustituir $x = 30$ en la ecuación
Sustituimos $x = 30$ en $y = 1.24x+3.805$. Entonces $y=1.24\times30 + 3.805$. Calculamos: $1.24\times30=37.2$, y $37.2+3.805 = 41.005\approx38$ (aproximadamente).
Answer:
(30, 38)
