Answer:
6 ft longer (total length of 15ft)
Step-by-step explanation:
the initial dimensions are:
length:
width:
the area area of the garden is given by:
so the original area is:
Since we need the area to be , and we can only change the length, the width will still be 8ft.
We substitute the value of the new area and the width to the equation for the area:
and we clear for the new length:
The length of the garden for the area to be , must be 15ft.
This means that if originally the length was 9 ft, now it has to be 6 ft longer.
20x(5/100)=1
That is the interest after one year
Add to the principal:20+1=21
Answer:
Convenience sampling.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Quota sampling.
6. Convenience (opportunity) sampling.
Convenience sample can be defined as a sampling technique in which the representatives to be used are easily accessible. For example, a researcher using a social media poll such as Twitter polls.
In this scenario, Catherine Chao, Director of Marketing Research, chooses thirty-six of her closest friends to participate in the testing of a new toothpaste package. Thus, Catherine's sample is a convenience sampling.
