Answer:
29.49% probability that a production time is between 9.7 and 12 minutes
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X between c and d, in which d is greater than c, is given by the following formula.
Production times are evenly distributed between 8 and 15.8 minutes and production times are never outside of this interval.
This means that
What is the probability that a production time is between 9.7 and 12 minutes?
.
So
29.49% probability that a production time is between 9.7 and 12 minutes

Analizando la frase de la paloma, podemos ver que la ecuación correcta será:
x + x/2 + x/4 + 1 = 100
Podemos analizar la frase de la paloma por partes.
"somos estas..."
definamos "estas" como x
"...más la mitad de las que estamos..."
entonces tenemos:
x + x/2
"... más la cuarta parte de las que somos..."
x + x/2 + x/4
"...y agregando una..."
x + x/2 + x/4 + 1
"...las 100 palomas serán..."
Interpretamos esto como:
"la expresión anterior es igual a 100"
Entonces escribimos eso:
x + x/2 + x/4 + 1 = 100
(las que somos (x) más la mitad de las que somos (x/2) más un cuarto de las que somos (x/4) más una (1) son igual a 100 palomas)
Así, concluimos que la ecuación que modela la situación descrita es:
x + x/2 + x/4 + 1 = 100
Que sería la opción 1.
