Answer:

X = savings, p= pay per hour

X+4p = 86 - - - - (1)

X+6p=104 - - - - - (2)

Re arrange equation (1)

X=86-4p-----(3)

Substitute (3) in (2)

86-4p +6p=104

86+2p=104. (subtract 86 from both side)

2p = 18. (divide by 2 from both side)

Then p =$9

By substitute in equation (1)

X = $50

Step2247 [10]

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)
