Answer:
Se vendieron 81 boletos de niños y 63 boletos de adultos.
Step-by-step explanation:
La cantidad de boletos vendidos es igual a:
(1)
En donde <em>a </em>es por adultos y <em>n</em> por niños
A su vez, el dinero gastado equivale:
(2)
Resolviendo la ecuación (1) para <em>a:</em>
(3)
Introduciendo (3) en la ecuación (2) tenemos:
Ahora podemos calcular el numero de boletos de adultos vendidos introduciendo <em>n</em> en la ecuación (3):
Entonces, se vendieron 81 boletos de niños y 63 boletos de adultos.

Answer:
(y − 2)² / 16 − (x + 3)² / 36 = 1
Step-by-step explanation:
The conjugate axis is the axis of symmetry. The transverse axis is the line connecting the vertices of the hyperbola. Since the transverse axis is parallel to the y-axis, this is a vertical hyperbola:
(y − k)² / a² − (x − h) / b² = 1
where (h, k) is the center of the hyperbola, a is half the length of the transverse axis, and b is half the length of the conjugate axis.
Here, the center is (-3, 2), a = 8/2 = 4, and b = 12/2 = 6.
(y − 2)² / 16 − (x + 3)² / 36 = 1
8 “choose” 5 = (8! / 5! x (8 - 5) ! )
8 “choose” 5 = (8! / 3! x 5!)
= (8 x 7 x 6 x 5 x 4 x 3 x 2 x 1) /
(5 x 4 x 3 x 2 x 1) /
(3 x 2 x 1)
= (8 x 7 x 6) /
(3 x 2 x 1)
= ( 7 x 4 x 2) = 56
Therefore there are 56 ways 5 singers can be selected from 8 that came to an audition.
