Answer:

Pedro would earn $703,500 more if he got his bachelor's degree in architecture over a 30 year career as opposed to an associate's degree in drafting.

Architect: 76,930 x 30 = 2,307,900

Anastasy [175]

9514 1404 393

Answer:

  321.25 kg

Step-by-step explanation:

The given relations are ...

  b = 2s

  4b +4s = 771

Substituting for b, we have ...

  4(2s) +4s = 771

  12s = 771

  s = 64.25

  b = 2s = 128.50

Then the weight of interest is ...

  b +3s = 128.50 +3(64.25) = 321.25 . . . . kg

Systematic random sampling has become a popular method of drawing samples in research practices because _____.
dolphi86 [110]

it is a relatively easy way to draw a sample while ensuring randomness is the answer.

Systematic sampling is a probabilistic sampling method in which a researcher selects members of a population at regular intervals. For example, select every 15 people from the list of populations. If the population is in random order, this can mimic the benefits of a simple random sample.

These are generally preferred by researchers because they are easy to implement and understand. The important assumption that the results represent the majority of the normal population ensures that the entire population is sampled equally. The process also provides a higher level of control for systematic sampling compared to other sampling methods. systematic sampling also has a lower risk factor because the data is unlikely to be contaminated.
