Answer:
50%
Step-by-step explanation:
The chances of getting either heads or tails on a coin is 50/50. Convert that to probability and that is 1/2. Convert it to percentage of 100 and it is 50%.
Only time a coin isn't 50/50 is if the coin itself is a weighted coin.
If the discriminant of a quadratic equation is equal to -8, there are two complex roots.
<h3>Discriminant of a quadratic equation</h3>
The discriminant is used to determine the nature of quadratic equations.
The formula for calculating discriminant is given as:
D = b^2 - 4ac
If the discriminant is negative, it means that the nature of the solution will be a complex number.
Hence if the discriminant of a quadratic equation is equal to -8, there are two complex roots.

The correct answer is -The position changes, and the angles remain congruent. or C.
The size does not change because the shape is only moving to new coordinates not growing or shrinking.
This means the shape also does not change.
When you translate a shape in geometry it means you are changing the position. But the shape will remain the same, meaning the angles remain congruent.
