I hope this might be able to help you.
Since the value of the car slowly decreases each year and each year is represented by <em>y</em>, the function is 24,000-1750y=f(x).
Respuesta:
(2945.411; 3054.589)
Explicación paso a paso:
Dado ;
Tamaño de la muestra, n = 50
Media, xbar = 3000
Desviación estándar, s = 200
Nivel de confianza, Zcrítico al 95% = 1,96
El intervalo de confianza se define como:
Xbar ± margen de error
Margen de error = Zcrítico * s / sqrt (n)
Margen de error = 1,96 * 200 / sqrt (50)
Margen de error = 54.589
Límite inferior = (3000 - 54.589) = 2945.411
Límite superior = (3000 + 54.589) = 3054.589
(2945.411; 3054.589)
Answer:24
Step-by-step explanation:
28=x+4
Collect like terms
x=28-4
x=24
29.99 + 16.99 = 46.98
46.98 + 0.08(46.98) = 46.98 + 3.76 = 50.74 <==
