The correct anwer is False
Explanation
According to the graph, it can be seen that a student has four hours of sleep as the minimum number of hours of sleep; two students have six hours of sleep, four students have six and a half hours of sleep, four have seven hours of sleep, three have seven and a half hours of sleep, five have eight hours of sleep, and one has eight and a half hours of sleep as maximum hours of sleep. Therefore, it can be affirmed that the statement that the difference between the maximum amount and the minimum number of hours is two and a half hours is false because between four hours and eight and a half hours there are four and a half hours of difference. So, the correct answer is False.
Answer:
Number A is correct I think, coz if uu take the feet convert them into decimals u'll get accurate answers
Yes they are equivalent to each other
In order to find the number of hours it takes to do the full rotation we separate into pieces the days, hours, and minutes and convert each of them separately.
using the conversion factor from days to hours we get that
then we get that
hours does not need a conversion factor, meaning that
continue by converting the minutes using the following conversion factor
then,
To complete add all the results together
It takes mercury 922.5 hours to complete a full rotation.
4%of 500 = 20
500 plus or minus 20 gives range as (480,520)
