Answer:
D
Step-by-step explanation:
P(3) = ⅙
P(5) = ⅙
Trials are independent so,
P(3 then 5) = 1/6 × 1/6 = 1/36
Answer:
x + 4
Step-by-step explanation:
(x - 9)(x + 4)
FOIL
x^2 + 4x - 9x - 36 = x^2 - 5x - 36
Answer:
F. 3 5/6
Step-by-step explanation:
3/5b - 1/2 = 1 4/5
Add 1/2 to both sides. To do this make the 4/5 have a common denominator of 10 by multiplying it by 2/2. Make 1/2 have a common den. of 10 by multiplying it by 5/5.
- 4/5 * 2/2 = 8/10
- 1/2 * 5/5 = 5/10
Now you can add.
3/5b = 1 13/10, which can be simplified to 2 3/10.
To isolate b, divide both sides by 3/5. This is the same as multiplying by 5/3 (reciprocal). First make 2 3/10 an improper fraction.
23/10 * 5/3 = 115/30
Simplified: 3 5/6
12 face cards ; 13 spade cards ; 25 cards total
Face cards - Jack, Queen, King
4 suits so 4 (suits) x 3 (faces) = 12 cards for face
52 (cards total) divided by 4 (suits) = 13
Spades - 13
100% = 320
20% = Blue tiles
35% = White Tiles
100% - 55% = Red Tiles = 45%
45% of 320
320 x 0.45 = 144 Red tiles
