1. Por ejemplo, si 15, 12, 12, 13 y 14 son las edades de 5 alumnos del primer grado de una secundaria nocturna Calcula la media
la mediana
y la moda
Si se inscribe un
alumno trabajador de 25 años Calcula de nuevo la media
la mediana
y la moda
Explica que pasó con esas medidas ¿cuál seria la medida que representa mejor la edad de
ese grupo de alumnos?
2. ¿Cuál es el rango de las edades del grupo de 5 alumnos? y del grupo de 6 alumnos?​

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
