X^3-(2y)^3
( x-2y)(x^2+x * 2y+4y^2)
final answer ( x-2y)(x^2+2xy+4y^2)
S = 15.47 units
Step-by-step explanation:
First, convert the degree angle into radians:
68° × (π/180) = 1.19 rad = theta
The arc length S is given by
S = r × theta
= (13 units)(1.19 rad)
= 15.47 units

The frequency of revision times is given by the product of the frequency
density value and the class width.
Correct response:
- The number of students are <u>72 students</u>
<h3>Methods of calculation using a histogram</h3>
The estimate of the number of students who revised for less than 45
minutes is given by the area, <em>A,</em> under the histogram to the left of the 45
minute mark as follows;
Frequency, f = Frequency density × Class width
Number of students = ∑f
Therefore;
A = 5 × 2 + 10 × 2.2 + 20 × 1.6 + 10 × 0.8 = 72
- The number of students that revised for less than 45 minutes = <u>72 </u>students
