This is not a math problem, i think. you should post it on biology.
the answer is e.
i'd like to explain it to you, but sorry, i can't, because i'm not a native english speaker. i can't explain such a difficult problem in english.
Answer:
<h2>
A. is a list of population elements from which the sample will be drawn</h2>
Step-by-step explanation:
Sampling frame is the list of people or items from which a sample is taken.
Sampling is used because it is almost impossible to study entire population. Sampling allows us to find information about a population on the basis of results from a subset of the population, without studying every individual. It is easier and cost effective process.
The whole number would be one and the remainder is 5. hope it helps.
Let the time taken by Vince to complete the race was x hours.
Maury completed the race 1.5 hours faster. This means Maury complete the race in (x - 1.5) hours.
Average Speed of Maury = 16 miles per hour
Average Speed of Vince = 12 miles per hour
Distance = Speed x Time.
For Maury:
Distance = 16(x - 1.5)
For Vince:
Distance = 12x
Since the distance covered by both was the same, we can equate the two equations as:
16(x - 1.5) = 12x
16x - 24 = 12x
4x = 24
x = 6
This means Vince complete the race in 6 hours.
Distance = Speed x Time = 12 x 6 = 72 miles
Thus, the total distance of the race was 72 miles.
