The interest earned by $318 investment is 9/100 x 318= $28.62
1) Work out what 1/5 of 12 is
To do this, we divide 12 by 5
12/5 = 2.4
2) Multiply 2.4 by 15
2.4 x 15 = 36
<em>If you don't like decimals, you can also do it this way...
</em>
This can be rewritten as 15 x 1/5 x 12
Multiplications alone can be performed in any order
1) Work out what 1/5 of 15 is
1/5 of 15
15/5 = 3
2) 3 multiplied by 12
3 x 12 = 36
2n-9-5-8n+4n
= 2n-14-4n
=2n-14
Answer: Cluster Sampling
Step-by-step explanation: Sampling is the process of collecting a representative of a particular Population of persons, activities, materials etc in order to use them for an experiment or research. Sampling can be done in different ways which include Cluster Sampling, random Sampling, stratified Sampling etc.
The activities of the Pollster using a random number to choose the residents of a given location is a Sampling method by Clustering.
Cluster Sampling is the process of identifying the cluster of participants representing the population and their inclusion in the sample group.
Answer:
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 3 + 9 = 12
Part A = 3 and Part B = 9 are numerators for each fraction.
The fractions are then:
3/12 and 9/12
Meaning:
Part A is 3/12 of the whole
Part B is 9/12 of the whole
Reducing the fractions, it is also true that:
Part A = 1/4 of the whole
Part B = 3/4 of the whole
