Hello,
sin² x-cos² x=sin² x-(1-sin² x)=2sin² x-1
==============================
There are 12 cards with different letters & patterns. The probability of randomly choosing [random card] is #[random card]/total cards.
Think of that as ratio as a %chance or probability of written as P(X). The question says to write the %chance as a fraction.
1) 2/12 = 1/6
2) 2/12 = 1/6
3) 0/12 = 0
4) 12/12 = 1
5) This is tricky. M & T would imply one card with both letters on it. 0/12 = 0
6) 4/12 = 1/3
7) 6/12 = 1/2
8) 5/12
9) 3/12 = 1/4
10) 8/12 = 2/3
11) 10/12 = 5/6
12) Odds = [favorable]:[unfavorable] = 5:7
Answer:M=24
Step-by-step explanation:
Step-by-step explanation:
√121 - √-192 - √4 + √-48
= 11 - 192i - 2 + 48i
= 9 - 144i
= 9(1 - 16i).
