s of 25 are readied for shipment and a sample of 3 is tested for defectives. If any defectives are found, the entire box is sent back, for 100 percent screening. If no defectives are found, the box is shipped.
Q: Now suppose the manufacturing company decides to change its acceptance scheme. Under this new scheme an inspector takes one at random, inspects it, and then replaces it in the box; a second inspector does likewise. Fianlly a third inspector goes through the same procedure. The box will not be shipped if any of the three find a defective.

Problemas de razonamiento división de números decimales. Ayer Susana se fue de viaje a visitar a unos familiares. Recorrió 135,7

Usando las relaciones entre velocidad, distancia y tiempo, se encuentra que ella condujo a una velocidad media de 90,5 km/h.

--------------------------

La <u>velocidad </u><u>es la distancia dividida por el tiempo</u>, por lo que:

v = \frac{d}{t}

  • Total de 135,75 km, o sea, d = 135,75
  • Llego en 1,5 horas, o sea, t = 1,5

La velocidad es:

v = \frac{d}{t} = \frac{135,75}{1,5}

División de decimales, o sea, seguimos multiplicando los números por 10 hasta que ninguno sea decimal:

v = \frac{135,75}{1,5} = \frac{1357,5}{15} = \frac{13575}{150} = 90,5

Ella condujo a una velocidad media de 90,5 km/h.

The sum of 2 sides of a triangle needs to be greater than the length of the 3rd side.

14 + 29 = 43 (this is greater than 41)

14 + 41 = 55 (this is greater than 29)

29 + 41 = 70 (this is greater than 14)


(14, 29,41) can form a triangle.
