Answer:
67,365,043,200
Step-by-step explanation:
A coin toss has 2 possible outcomes. A coin tossed 3 times has 2³ = 8 possible permutations.
A standard die has 6 possible outcomes. A die rolled 4 times has 6⁴ = 1296 possible permutations.
The number of ways 4 cards can be chosen from a deck of 52 without replacements is 52×51×50×49 = 6,497,400.
The total number of possible outcomes is:
8 × 1296 × 6,497,400 = 67,365,043,200
Answer:
(2,1,0)
Step-by-step explanation:
3x+3y+6z=9
3(2)+3(1)+6(0)=9
6+3+0=9
6+3=9
9=9
x+3y+2z=5
x(2)+3(1)+2(0)=5
2+3+0=5
2+3=5
5=5
3x+12y+12z=18
3(2)+12(1)+12(0)=18
6+12+0=18
6+12=18
18=18
Answer:
c
Step-by-step explanation:
160 = 16 * 10 = 4 * 4 * 2 * 5 = 2 * 2 * 2 * 2 * 2 *5
