Which of the following measurements could be the side lengths of a right triangle? A. 66 in, 88 in, 110 in
MAXImum [283]
So the way to figure out the sides of a right triangle, is basically

A^2 + B^2 = C^2

Letter A is the only one that would work, because the first number squared (times itself), added to the second number squared, would equal the third number squared. This is a basic principle of the pythagorean theorem, which I can explain in more detail if you'd like. :)

Los 75 postulantes que fueron aceptados tuvieron notas desde 16 hasta a 20. Si el grupo se hubiera desempeñado de modo homogéneo
joja [24]

Answer:

Tenemos 75 postulantes, y sus notas están en el rango desde 16 hasta 20.

1) si el grupo es homogéneo y todos tienen la misma nota, entonces todos van a tener la nota media en el rango (16, 20)

Para encontrar esta nota calculamos la suma entre ambos extremos y lo dividimos por 2.

Media = (16 + 20)/2 = 36/2 = 18

La nota sería 18.

2) entre 16 y 20 tenemos:

16, 17, 18, 19 y 20

tenemos 5 notas distintas, entonces si agrupamos a los estudiantes por nota, tendríamos 5 grupos.

3) En una distribución normal, el grupo mas grande debería coincidir con la media del intervalo. Ya sabemos que la media es 18, entonces es esperable que la nota del grupo mas grande sea 18.

4) Si los estudiantes se ordenan en fila según notas tendríamos:

Fila con nota 16

fila con nota 17

fila con nota 18

fila con nota 19

fila con nota 20

Podemos ver que la fila del medio es el grupo con nota de 18
