The correct answer for the question that is being presented above is this one:
<span>
To find the mean of a set, add up all of the numbers and divide by how many numbers you have. For the first set:
</span>u = (10.7+2.4)/2 = 6.55
For the second set:
u = (13.7 + 2.5)/2 = 8.1
<span>To find the mean absolute deviation, (MAD) find the mean of the distances of each number from the mean.
</span>First set:
MAD = (|10.7-6.55| + |2.4-6.55|)/2 = 4.15
Second set:
<span>MAD = (|13.7-8.1| + |2.5-8.1|)/2 = 5.6</span>
The means-to-MAD ratio is simply that, divide one by the other and that's it.
For the first set:
6.55 / 4.15 = 1.57831325
For the second set:
8.1 / 5.6 = 1.44642857
The correct answer is letter B

Answer:
El problema parece incompleto, asi que lo respondere en una forma general.
Sabemos que para un rectángulo de largo L y ancho W, el área se calcula como:
A = L*W
En este caso, sabemos que el área del rectángulo es:
A = 156cm^2
Entonces tenemos:
156cm^2 = L*W
No tenemos más información del rectángulo, entonces solo podemos llegar a algo como:
L = (156cm^2)/W
Que nos habla de la relación entre el largo y el ancho del rectángulo.
