The first one is out, because it isn't fair. We want a 50/50 chance to win. If we add 2 cards with stars, then your chance of winning increases too much(as much as that'd be great). If we take away 2 blank ones, it would be fair, but we want to still have 10 cards. So the only choice left is to add a start to 1 of the blank cards.

Do you have a graph for your question?
Answer:
the 3rd one -6, -3.2, 0.4 4.8
Step-by-step explanation:
this is because in the negatives -6 is less then -3.2 but positive 0.4 is greater then -3.2 so even if it looks like larger number if there is a negative sign in front if that number it is a smaller number then a number that looks smaller but has a negative sign in front of it.
Answer:
x = 21
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the given angles and equate to 180, that is
x -4 + 3x + 100 = 180, that is
4x + 96 = 180 ( subtract 96 from both sides )
4x = 84 ( divide both sides by 4 )
x = 21
