If a sequence terminates it is called a finite sequence
Answer:
I think the answer would be C
Step-by-step explanation:
I think it might be D
The size of the sample space is the total number of possible outcomes. For example, when you roll 1 die, the sample space is 1, 2, 3, 4, 5, or 6. So the size of the sample space is 6. Then you need to determine the size of the event space.
Answer: The length of the square is 
Step-by-step explanation:
By definition, the area of a Regular polygon can be calculated with the following formula:

Where "s" the length of any side of the polygon and "n" is the number of sides .
According to the information given in the exercise, you know that:

Since an hexagon has six sides, you know that:

Therefore, its area is:

The formula to find the area of a square is:

Where "s" is the length of any side of the square.
Since that regular hexagon has the same area as this square, you can substituting the area calculated above into the formula for calculate the area of a square, and then solve for "s".
Then you get:

(x + 5/2 * 2/5)^2 = -5/2
(x)^2 sqrt 2 = -5/2 sqrt 2
(x) = i sqrt10/2 - 5/2, i sqrt10/2 - 5/2
