Step-by-step explanation:
12-6+4
X shortest piece
X+6 middle piece
X+8 longest piece
Add them
3x+14=56
3x=42
X=42/3=14
Answer:
<u>X</u> <u>Y</u> <u>(</u><u>X,</u><u>Y)</u>
-4 14. (-4,14)
-3 12. (-3,12)
-2 10. (-2,10)
-1 8. (-1,8)
0 6 (0,6)
1 4. (1,4)
2 2. (2,2)
1st urn....4 green balls, 6 blue balls.....10 total balls....probability of drawing a blue ball in urn 1 is : 6/10 reduces to 3/5
2nd urn...6 green balls, 2 blue balls....8 total balls...probability of drawing a blue ball in urn 2 is : 2/8 reduces to 1/4
probability both balls are blue : 3/5 * 1/4 = 3/20 <==
