Given:





To find:
The variance. of combined set.
Solution:
Formula for variance is
...(i)
Using (i), we get




Similarly,




Now, after combining both sets, we get




Therefore, the variance of combined set is 15.4.
Answer:
I did it is in my profile
Step-by-step explanation:
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 )
