Answer:
20 is the answer
Step-by-step explanation:
Answer:
15.38% or 0.1538
To know:
[] There are 4 cards that are 8s in a standard 52-card deck
[] There are 4 aces in a standard 52-card deck
Step-by-step explanation:
[] Wanted outcomes divided by possible outcomes
4 + 4 = 8 wanted outcomes
52 possible outcomes
8 / 52 ≈ 0.1538
[] Converting to a percentage
0.1538 * 100 = 15.38%

Answer:
y = -2x -3
Step-by-step explanation:
- the altitude trough F is a perpendicular line to the line DE
- find slope of line DE
D ( x2 = -5, y2 = -1); E (x1 = 3, y1 = 3)
slope m = (y2-y1) / (x2-x1) = (-1-3) / (-5-3) = -4/ -8 = 1/2
-find equation of the altitude trough F
lines that are perpendicular have the slope negative reciprocal (negative reciprocal of 1/2 is -2)
y= -2x +b , for point F(1, -5)
-5 = -2*1 +b, add 2 to both sides
-5 +2 = b, combine like terms
-3 =b
equation of the altitude trough F is y = -2x -3
