Answer:
On a fair die, half the numbers are even and half the numbers are odd. So, the probability for a single roll of getting an even number or an odd number is 12. So, the odds are 7:1 against the desired outcome

Answer:
D
Step-by-step explanation:
We put 2nd equation into 1st equation and get y:

We can't seem to come to a solution.
Also let's rearrange the 2nd equation into y = something form:
x = 7y + 1
7y = x - 1
y = 1/7 x -1
As we can see BOTH the lines have the same SLOPE, the number before x, which is 1/7 and we know that lines with same slope are parallel, they never intersect.
Having a solution to a system means their intersection point, since they are parallel lines, they don't intersect, and hence DO NOT HAVE A SOLUTION.
D is the correct choice.
Answer:
Trench warfare was a technique used to fight in World War 1. As they could hide/defend there. Get supplie there. They could even have medical areas there, but the problem was a stalemate as that was such a thing that no one attacks and they stay without moving on in the battle.
X is 2 because 96•45 is 2.1
