1 million is 1 x 10^6
1 billion is 1 x 10^9
1 trillion is 1 x 10^12
So 12 trillion miles is 12 x 10^12 which converts to 1.2 x 10^1 x 10^12 = 1.2 x 10^13
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.

Answer:
Austerity is a set of political-economic policies that aim to reduce government budget deficits through spending cuts, tax increases, or a combination of both. Austerity measures are often used by governments that find it difficult to borrow or meet their existing obligations to pay back loans. The measures are meant to reduce the budget deficit by bringing government revenues closer to expenditures. This reduces the amount of borrowing required and may also demonstrate a government's fiscal discipline to creditors and credit rating agencies and make borrowing easier or cheaper as a result.
