Okay so first we need to find how many days are in March and February. March has 31 days and because this year was a leap year February has 29 days.
The next step is to convert days to hours.
March: 31x24=744
February: 29x24=696
Now its time to graph
The next step is to convert days to hours.
March: 31x24=744
February: 29x24=696
Now its time to graph
Answer:
Firstly we calculate the number of hours of both months.
This year is not a Leap year. So, the number of days of February is 28
and the number of days of March is 31
So, Number of hours February has 28 × 24 = 672 hours
and, Number of hours March has 31 × 24 = 744 hours
The bar graph is the best visual representation when we have categorical data. It is drawn by using a rectangular bar where the length of the bar represents height or frequency.

Answer:
The fraction of the students who failed to went partying =
Step-by-step explanation:
Let total number of students = 100
No. of students partied are twice the no. of students who not partied.
⇒ No. of students partied = 2 × the no. of students who are not partied

⇒ No. of students partied before the exam = × 100
⇒ No. of students partied before the exam = 20
No. of students who not partied before the exam =
Thus the fraction of the students who failed to went partying =
