Answer:
Optical axis
Step-by-step explanation:
Optical axis is the rotational symmetry axis of the surfaces.
A line with a certain degree of rotational symmetry is called as the optical axis in an optical system.
It is the straight line that passes through the geometric center of the lens and joins two curvature centers of its surfaces.
It is also called as the principal axis.
a) if the two gloves someone receives might both be for the left hand or right hand.
b) if each sister gets one left and one right.
Soln:
a) So i thought about dissectng the problem first into finding the number of ways in which I could make pairs of gloves:
C(12, 2)
then I asked how many ways could the sets of gloves be assigned amongst the 6 sisters:
<span><span>6!</span><span>6!</span></span>
and taking the product of this would give me the amount of ways this could occur:
= C(12,2) * 6!
then for part b)
using this same idea except:
C(6,1) C(6,1) for the left and right glove each .
the C(6,1)*C(6,1)*6!
Right way to think them through?

Answer:
Las opciones no se pueden ver, así que responderé de una forma general.
Primero rompamos la frase en partes más cortas
"cuatro veces un número..."
Esto se escribe como 4*N, donde N es el número.
"... la suma de dos
números"
Esto se escribe como K + M
donde K y M son dos números, entonces K + M es la suma de dos números.
Entonces:
"cuatro veces un número dividido por la suma de dos
números"
Se escribirá como:
(4*N)/(K + M )
