1. En una escuela secundaria hay 700 alumnos, de los cuales 30% cursan primer grado. ¿Cuántos son los alumnos que cursan primer grado? *

i believe the answer is d.

hope it you! : d

i think that you should ask google for the answer to that problem because if we don't know it google does

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5
