Andreas93 [3]

Answer:

d. None of the above.

Step-by-step explanation:

<em>a. By the law of large numbers, it would again be 46%. </em>

FALSE. This proportion (46%) is a sample statistic, that can or can not be repeated in another sample.

<em>b. By the law of large numbers, the smaller (second) survey will certainly produce a sample proportion farther from the true population proportion than the larger (first) survey. </em>

FALSE. Smaller samples will produce wider confidence intervals for the estimation of the population proportion, but larger samples does not necessarily gives us better point estimations of the true proportion. A small sample can be closer to the true proportion than a large sample, although is less probable.

<em>c. The proportion computed from the sample of 5000 people would be more accurate because smaller samples tend to be more homogeneous than larger samples. </em>

FALSE. There is no evidence to claim that smaller samples are more homogeneous.

<em>d. None of the above.</em> TRUE

Answer:

  1. 3.04 m
  2. 18

Step-by-step explanation:

The midsegment of a triangle is half the length of the side it is parallel to.

1. For a distance of 6.08 m between wall plates, the colar tie will be half that, or 3.04 m.

2. The perimeter of ΔXYZ is ...

... 10 + 12 + 14 = 36

The sides of ΔABC are half the length of the sides of ΔXYZ, so the perimeter of ΔABC is half the perimeter of ΔXYZ.

... perimeter of ΔABC = 36/2 = 18

Alex Ar [27]

Ok, primero haces estas hostilidades de considerable duración y magnitud. En el uso de las ciencias sociales, se agregan ciertas calificaciones. Los sociólogos suelen aplicar el término a tales conflictos sólo si se inician y conducen de acuerdo con formas socialmente reconocidas. Tratan la guerra como una institución reconocida en la costumbre o en la ley. Los escritores militares suelen limitar el término a las hostilidades en las que los grupos contendientes tienen el mismo poder para hacer que el resultado sea incierto durante un tiempo. Los conflictos armados de estados poderosos con pueblos aislados e impotentes suelen denominarse pacificaciones, expediciones militares o exploraciones; con los estados pequeños, se les llama intervenciones o represalias; y con grupos internos, rebeliones o insurrecciones. Tales incidentes, si la resistencia es lo suficientemente fuerte o prolongada, pueden alcanzar una magnitud que les dé derecho al nombre de "guerra".
