Step-by-step explanation:
Given are 3 data sets with values as:
(i) 8 9 10 11 12 ... Mean =10
(ii) 7 9 10 11 13 ... Mean =10
(iii) 7 8 10 12 13 ... Mean =10
We see that data set shows mean deviations as
(i) -2 -1 0 1 2
(ii) -3 -1 0 1 3
(iii) -3 -2 0 2 3
Since variance is the square of std deviation, we find that std deviation is larger when variance is larger.
Variance is the sum of squares of (x-mean). Whenever x-mean increases variance increases and also std deviation.
Hence we find that without calculations also (i) has least std dev followed by (ii) and then (iii)
(i) (ii) (iii) is the order.
b) Between (i) and (ii) we find that 3 entries are the same and 2 entries differ thus increasing square by 9-4 twice. But between (ii) and (iii) we find that
increase in square value would be 4-1 twice. Obviously the latter is less.
The answer is 3 out of 8
there are 8 sides but there are only 3 so 3/8 or 3 out of 8
Answer:
La oferta 2 oferce el mayor valor final. Es la que debería ser aceptada.
Step-by-step explanation:
Dada la siguiente información:
Oferta 1:
$150.000 hoy y $200.000 dentro de 10 años.
Oferta 2:
$30.000 al final de cada uno de los próximos 10 años.
Tasa de interés= 14%
<u>Para decidir cuál de las dos ofertas es mejor, debemos calcular el valor final:</u>
<u>Oferta 1:</u>
VF= VP*(1+i)^n
VF= 150.000*(1,14^10) + 200.000
VF= $2.261.523,48
<u>Oferta 2:</u>
VF= {A*[(1+i)^n-1]}/i
A= cash flow anual
VF= {30.000*[(1,14^20) - 1]} / 0.14
VF= $2.730.747,83
