The Formula for Percent Proportion is Parts /whole = percent/100. This formula can be used to find the percent of a given ratio and to find the missing value of a part of a whole.

Total frequency, N = 6 + 7 + 16 + 30 + 43 + 29 + 22 + 14 + 3  = 170

Proportion of at least 85 = P(x > 85) = n(x > 85) / N = (170 - 6 - 7) / 170 = 0.9235

Proportion of less than 95 = P(x < 95) = n(x < 95) / N = (170 - 14 - 3) / 170 = 0.9000

A proportion of less than 90 is approximately the mean of the Proportion of less than 89 and the Proportion of less than 91

Proportion of less than 89 = P(x < 91) = n(x < 91) / N = (6 + 7 + 16 + 30 ) / 170 = 0.3470588

Proportion of less than 91 = P(x < 91) = n(x < 91) / N = (6 + 7 + 16 + 30 + 43) / 170 = 0.6

Proportion of less than 90 = (0.3470588 + 0.6)/2  = 0.4735

Cronología de los principales momentos de la batalla del pichincha
stiv31 [10]

Answer:

La Batalla de Pichincha, librada el 24 de mayo de 1822, fue el combate final de la Guerra de Independencia de Ecuador, que significó la derrota de los españoles en dicho conflicto.

El 21 de mayo, Sucre posicionó a su ejército al este del Cerro Panecillo para atraer a los españoles al ataque y provocar una batalla fuera de la ciudad. En la noche del 23 al 24 de mayo, pasó por alto las posiciones de los españoles y giró hacia el noroeste para escalar las laderas del volcán Pichincha, subiendo a una altitud de más de 3.500 metros. La caballería no pudo escalar el empinado camino y, por lo tanto, quedó en la base del volcán.  En respuesta, Aymerich envió a los oficiales Carlos Tolrá y Nicolás López con tres batallones de infantería, dispuestos al ataque. El enfrentamiento, que incluyó disparos y combate cuerpo a cuerpo, se saldo con cuatrocientos muertos realistas y doscientas del lado de los patriotas ecuatorianos.

Un día después, el 25 de mayo de 1822, los españoles firmaron la rendición, con lo cual Ecuador fue liberado de la corona española y la guerra terminó.
