Answer:
Eggs 2 3 4
Milk 6 9 12
Ratio 3/1 3/1 3/1
Step-by-step explanation:
Look at the second column with 2 eggs and 6 cups of milk.
6 cups milk and 2 eggs. The ratio of the number of cups of milk to number of eggs is 6/2, which is the same as 3/1 in the second column. The number of cups of milk is always 3 times the number of eggs.
If you know the number of eggs, multiply by 3 to get the number of cups of milk. 3 * 3 = 9 in the third column.
If you know the number of cups of milk, divide by 3 to get the number of eggs. 12/3 = 4 in the fourth column.
Eggs 2 3 4
Milk 6 9 12
Ratio 3/1 3/1 3/1
Answer: 2. To avoid bias
Explanation:
The random sampling can be defined as the method of selecting the samples from the population of interest randomly. The main advantage of this method is to select the samples from the target population and eliminating the bias in sampling. The random sampling is least choice of sampling for research purpose as the researcher wants to choose only selected desired samples for the study.
Answer:
0.0082
Step-by-step explanation:
The n th term of a geometric sequence is
= a₁ 
where a₁ is the first term and r the common ratio
Here a₁ = - 2 and r = - 
, thus
= - 2 
= - 2 × - 
= 
≈ 0.0082 ( nearest ten- thousandth )
