Answer:
Mathematically, two events are considered to be independent if the following relation holds true,
∵ P(B | A) = P(B)
For the given case,
P(D | L) = P(D)
But
0.13 ≠ 0.47
Since the relation doesn't hold true, therefore, "being left-handed" and "being a Democrat are not independent events.
Step-by-step explanation:
We are given that
Left-handed = P(L) = 0.40
Democrats = P(D) = 0.47
If a president is left-handed, there is a 13% chance that the president is a Democrat.
P(D | L) = 0.13
Based on this information on the last fifteen U.S. presidents, is "being left-handed" independent of "being a Democrat?

Answer:
Let x = cost of your friend's lunch.
x + x + 3 = 19
x= 8
O( 0,0 ) A(9 , 0 ) D( 0,3 ) ( 9, 2) , ( 6 , 3 ) that are vertices of the feasible region.
What do math vertices mean?
- The spots where two or more line segments or edges intersect are known as vertices in forms (like a corner). Vertex is the singular form of vertices.
- For instance, a cone only has one vertex whereas a cube has eight. Although vertices are occasionally referred to as corners, the term "vertex" is preferable when discussing 2D and 3D designs.
The line 2x + 6y = 30
when x = 9 , 18 + 6y = 30
y = 2
So B = ( 9, 2)
So, C= ( b , 3 )
then , we can show O( 0,0 ) A(9 , 0 ) D( 0,3 )

On your X-axis, go to -5 and identify which Y-coordinate it is. For this problem, it would be -2.
