686 barrels left. If I'm not mistaken this should just be simple subtraction
Answer: the first one
Step-by-step explanation: the number is 42 45 45 46 and 48 are all close together while the number 16 is off to the whole other side
First, you add up the total number of students because we would base our percentage one this.
Total number of students = 1+4+5+10+20+10+5
Total number of students = 55
Now, let's count how many of them got a score of more than 70. For this, you would only count the students belonging to 70-under 80, 80-under 90 and 90-under 100.
Students who got more than 70 = 20+ 10 + 5 = 35
Therefore the percentage is equal to:
Percentage = 35/55 * 100 = 63.64%
q = 10p because all of them are multiplied by ten
