Answer:
x=21.
Step-by-step explanation:
First you distribute 3 to the parenthesis. You should get 3x-21=42 at this point. Then you add 21 to 42 to get 63. Here you should be at 3x=63. Divide 63 by 3 to get x=3
Answer:
9
Step-by-step explanation:
2,3,4,7,7,7,9,9,14,17,21
21,17,14,9,9,7,7,7,4,3,2
3,7,7,7,9,9,17,21
Answer: So the number of outcomes with exactly 4 tails is 720/2/24 = 15. Finally we can now calculate the probability of getting exactly 4 tails in 6 coin tosses as 15/64 = 0.234 to 3 decimal places.
Step-by-step explanation:
-3-4 -32x=3×8x
-3-4-32x=24x
-6=32x+24x
-6=56x
:. x=-28/3
Y-4= -3(x-3)
First you'll distribute the -3(x-3) and you should get -3x+9 (a negative divided by a negative is a positive)
So your new equation will be y-4=-3x+9. Next you'll get rid of the -4 y adding 4 on both sides of the equation. So you should get y=-3x+13. So points you could use is <span><span>(<span>0,13</span>)</span>,<span>(<span>1,10</span>)</span>,<span>(<span>2,7</span>)</span></span><span />
