If each shirt needs eight buttons you find out what times (×) Eight equals (=) 80
8×10=80
So Eight buttons per shirt
So together they made 10 shirts
but they ask how many Timor made so you do 10 ÷ 2= 5

Timor Made Five (5) Shirts

Answer:

5 shirts.

Step-by-step explanation:

Let x be the total number of shirts.

We have been given that each shirt needs 8 buttons, so number of button on x shirts would be 8x.

We are told that together the tailors attach 80 buttons. We can represent this information in an equation as:

8x=80

\frac{8x}{8}=\frac{80}{8}

x=10

Therefore, both tailors completed 10 shirts.

Since they split the work evenly, so Timor will complete half of the 10 shirts that is 5 shirts.

Therefore, Timor completed 5 shirts.

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
