Z score = (x-μ)/σ
2 = (x-50) / 10; solve for x
20= x-50 and x = 70 : TRUE
We can notice that : Line Passes through the Points (1 , 2) and (4 , -4)
Let us find the slope of the line in order to write the Equation of the Line.
Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :
Points are (1 , 2) and (4 , -4)
here x₁ = 1 and x₂ = 4 and y₁ = 2 and y₂ = -4
Equation of the Line passing through (1 , 2) and having slope -2 is :
⇒ y - 2 = -2(x - 1)
⇒ y = -2x + 2 + 2
⇒ y = -2x + 4
The pic is blurry I can’t understand it
Answer:
The vector AB is represented by (11, 2).
Step-by-step explanation:
Given two points on the same plane, we can determine the vector by this formula:
(1)
Where:
- Coordinates of point A.
- Coordinates of point B.
If we know that and , then the vector AB is:
The vector AB is represented by (11, 2).
