Answer:
D
Step-by-step explanation:
The y intercept is (0,2) so you can eliminate A and C because they have -2 and the slope is negative so you can eliminate B because it has a slope of +3 so you are left with D.
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)
Step-by-step explanation:
Convert the given value in cm into feet and inches.
<u>Use the unit rates:</u>
- 1 foot = 30.48 cm
- 1 inch = 2.54 cm
<u>Convert:</u>
- 170 cm = 170/30.48 feet = 5.58 feet (rounded)
- 170 cm = 170/2.54 inches = 66.93 inches
or
- 170 cm = 5 feet and 17.6 cm = 5 feet and 7 inches (rounded)
It is 5x5x5 which equals 125
