The equation of line CD in standard form is: B. 5x - 3y = 30
<h3>How to determine the equation of line CD in standard form?</h3>
Mathematically, the standard form of the equation of a straight line is given by this mathematical expression (linear function);
y = mx + c
Where:
- x and y are the points.
- m represents the slope, gradient, or rate of change.
- c represents the intercept.
Next, we would determine the slope of this line by using this formula:
Slope, m = Δy/Δx
Slope, m = Change in y-axis/Change in x-axis
Slope, m = (0 + 5)/(6 - 3)
Slope, m = 5/3
At point (6, 0), the point-slope equation of the line is given by:
y - y₁ = m(x - x₁)
y - 0 = 5/3(x - 6)
y = 5x/3 - 30/3
y = 5x/3 - 10
Multiplying all through by 3, we have:
3y = 5x - 30
Rearranging the equation, we have:
5x - 3y = 30

Step-by-step explanation:
From a, the original number is 100x the new number.
So,if the new number is 1unit --> the original is 100x 1unit --> 100units
Add the two numbers together --> 1unit + 100units --> 101 units
We also know that the difference between the two numbers is 136.62
So 100units - 1unit --> 136.62
99units -> 136.62
1unit --> 1.38
101units --> 139.38

Lower Quartile: Q₁ = ¹/₄(n + 1)
Q₁ = ¹/₄(10 + 1)
Q₁ = ¹/₄(11)
Q₁ = 2³/₄
Median: Q₂ = ¹/₂(n + 1)
Q₂ = ¹/₂(10 + 1)
Q₂ = ¹/₂(11)
Q₂ = 5¹/₂
Upper Quartile: Q₃ = ³/₄(n + 1)
Q₃ = ³/₄(10 + 1)
Q₃ = ³/₄(11)
Q₃ = 8¹/₄
Q₁ = 2³/₄
Q₂ = 5¹/₂
Q₃ = 8¹/₄
