Step-by-step explanation:
What is the probability of drawing a diamond card or an ace from a pack of 52 playing cards? The probability of drawing a diamond-faced card from a pack of 52 playing cards is easy to determine. Since there are 13 diamond-faced cards in the deck, the probability becomes 13/52 = 1/4 = 0.25.

Answer:
The area is the side lengths squared or multiplied by themselves. The three squares have very different areas based on their side lengths. I disagree that a square with 13 inch side length will have area 13. It will have area 13*13=169 square inches.
Step-by-step explanation:
The area of a square is A=s*s.
1st: A = 1*1 = 1 square inches.
2nd: A=1/2*1/2 = 1/4 square inches
3rd: A =2*2 = 4 square inches.
The area of a square with 1 unit side length is still 1. But a square whose side is less than 1 has a very small area and the square whose side length is greater than 1 has a much larger area. The area of a square is the square of its side length or its side length times itself.
Knowing this, a square with side length 13 will not have area 13 but area 169.
It's da last answer good luck but if it is wrong dnt sue me lol
If we add the 2 equations the terms in x dssappear and we get
2y = 1
so y = 1/2
Substitute in first equtaion:-
1/2 = - 1/2 x + 4
-1/2 x = 1/2 - 4 = - 7/2
x = -7/2 * -2 = 14/2 = 7
answer is (7, 1/2)
