So theres 366 days in a leap year,
you need to find hours, minutes, and then seconds
366 x 24 = 8,784 hours
8,784 x 60 = 527,040 minutes
527,040 x 60 = 31,622,400 seconds
31,622,400 seconds x 186,182 mps = 5.88 x 10^10
therefore light travels 5.88 x 10^10 in one leap year
For the first one just do the multiplication as you do normally.
For the second one, you have to put a zero behind before calculating the numbers in front
Answer:
The use of sampling would be best in the following situation:
a. The need for precise information is less important.
Step-by-step explanation:
Sampling:
It is such a process of analysis in which we divide a large proportion of data into smaller proportions called samples to determine the characteristics of that data.
- The option a is correct as in sampling, we take a smaller proportion from a large pool of data so when the precise information is less important, it is a good way to use sampling.
- The option b is not correct as the number of items comprising the population is always large.
- The option c is not correct as the likelihood of selecting a representative is relatively not small rather it is large.
- The option d is incorrect as the use of sampling is not appropriate in all of these situations.
