Answer:
45 different ways to fill the positions.
Step-by-step explanation:
Consider the provided information.
Management selection. A corporation plans to fill 2 different positions for vice-president, V₁ and Upper V₂, from administrative officers in 2 of its manufacturing plants. Plant A has 9 officers and plant B has 5.
We need to find the probability that 2 positions be filled if the Upper V₁ position is to be filled from plant A and the Upper V₂, position from plant B?
To fill the post of V₁ from plant A, which has 9 officers, we have 9 ways.
To fill the post of V₂ from plant B, which has 5 officers, we have 5 ways.
Therefore, the total number of ways are: 
Hence, 45 different ways to fill the positions.

Answer:
See explanation
Step-by-step explanation:
The first pair is (-4 and 8)
Because if we add those two values, i. e., 8 + (-4), we will get 4.
Again, the second pair is (-2 and 6). In that case, if we also add those two values, that is, 6 + (-2), we will get 4.
Finally, the third pair is (-1 and 5). Again, we will add the two values. 5 + (-1) = 4.
In each case, we can see that the addition of each pair is 4.Therefore, the total is similar in each pair after arranging the cards.
