Answer:
-0.2,-2.2,-0.2, 0.8, 1.8
Step-by-step explanation:
Given :Five people were asked approximately how many hours of TV they watched per week.
Their responses were as follows. 6 4 6 7 8
To Find : Find the deviations from the mean for these five data values
Solution :
Mean =
Mean =
Mean =
The deviations from the mean for these five data values: 6-6.2,4-6.2,6-6.2,7-6.2,8-6.2=-0.2,-2.2,-0.2, 0.8, 1.8
Hence the deviations from the mean for these five data values is -0.2,-2.2,-0.2, 0.8, 1.8
Answer:
1-
2X + 3Y = 330
2-
X + Y + Z = 3890
3-
1/3X + 2/3X = X
4-
X + Y = 27
Step-by-step explanation:
Para plantear ecuaciones para las siguientes situaciones se deben realizar los siguientes razonamientos lógicos:
1- Juan compró 2 panchos y 3 hamburguesas y le cobraron $330.
Panchos = X
Hamburguesas = Y
2X + 3Y = 330
2- Realizo un pago de la factura de luz, agua y cable en total me cobran $3890.
Luz = X
Agua = Y
Cable = Z
X + Y + Z = 3890
3- Un padre reparte un dinero X que recibió entre su esposa y su hijo, a su esposa le da el doble que al hijo.
Esposa = 2/3X
Hijo = 1/3X
1/3X + 2/3X = X
4- En el salón de clase hay 27 alumnos entre mujeres y varones.
Mujeres = X
Varones = Y
X + Y = 27
Answer:
70.4 meters
Step-by-step explanation:
A to B: 40²+10²=c² = 1600+100=c² = 1700=c² = c=√1700 = 41.23
B to C: 25²+15²=c² = 625+225=c² = 850=c² = c=√850 = 29.15
41.23+29.15=70.38
9t=c would be the answer since it's just asking for the equation
