Answer:

1. It reduces the probability of sampling bias.

2. A random sample will be more representative of the whole population.

3. Allows the researcher to determine the efficacy of the fertilizer.

Explanation:

Selecting a simple random simple from a large population is a widely used method in science. Researchers select a random sample so every individual, in this case seedling, has an equal chance to be selected.

Therefore, it is an accurate method that, although is not free from errors, avoids or reduces the probability of sampling bias. Selecting a truly random tomato seedling will be more representative of the whole population of seedling instead of selecting carefully a seedling that already has specific or desired characteristics. Hence, this random sampling will allow the researcher to determine the efficacy of the fertilizer.

Analyze the origins and development of slavery in Britain's North American colonies in the period 1607 to 1776.
kogti [31]
  • The origins of slavery in Britain's North American colonies can be traced back to the early 1600s, when the first African slaves were brought to the Virginia colony. At first, these slaves were used primarily for labor in the tobacco fields. However, by the mid-1700s, the use of slaves had spread to other areas of the colonies, such as the Carolinas and Georgia, where they were used for labor in the rice and indigo fields.

  • The development of slavery in the British colonies was largely shaped by the demand for labor. As the colonies grew and became more economically prosperous, the demand for labor increased. This led to the importation of more slaves from Africa. By the time of the American Revolution, there were an estimated 500,000 slaves in the British colonies.

North American colonies:

The British North American colonies were well-established communities that were tightly linked to the Atlantic and Caribbean commerce networks. Although religious ideals drove many settlers, others regarded the colonies as a chance to buy their own land, work for themselves, or strike it rich.

A transport truck is travelling at 24ms -1 . As it reaches the outskirts of a town it changes its speed to 10ms -1 . Calculate t
alexdok [17]

Answer:

Acceleration a =-1.75 m/s²

Explanation:

Given:

Initial speed u = 24 m/s

Final speed v = 10 m/s

Time taken t = 8 sec

Find:

Acceleration a

Computation:

a = (v-u)/t

a = (10-24)/8

a = -14 / 8

Acceleration a =-1.75 m/s²
