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%

Answer:
BC is 10 unit
BD is 15 units
Step-by-step explanation:
Here, given the end points of the line segments, we want to calculate BD and DC
Mathematically, the distance between two points can be calculated using the formula;
D = √(x2-x1)^2 + (y2-y1)^2
For BD, we have the following
D = √(14-5)^2 + (14-2)^2
D = √(9)^2 + 12^2
D = √81 + 144
D = √(225)
Distance BD is 15 units
For BC, we have the following
D = √(11-5)^2 + (10-2)^2
D = √(6)^2 + 8^2
D = √100
D = 10
