Answer:
x = 8 or x = -8
Step-by-step explanation:
x^4 - 256 = 0
<=>x^4 - 4^4 = 0
<=>(x - 8)(x + 8)(x^2 + 64) = 0
Case 1 :
x - 8 = 0
<=>x = 8 (choose)
Case 2:
x + 8 = 0
<=>x = -8 (choose)
Case 3:
x^2 + 64 = 0
<=>x^2 = -64 (nonsense)
so x = 8 or x = -8
Done :))
Answer:
Yes, x=1 is the solution
Step-by-step explanation:
You would divide both sides of the equation by 2, that leaves you with x+13=14
Next you would move your constant, which in this case is 13, so x=14-13
Then you would subtract the numbers by each other so 14-13 equals one which makes x=1
Answer:
0.47
Step-by-step explanation:
First, find P(X > 1.18).
(2 − 0) / 1 = (2 − 1.18) / x
2x = 0.82
x = 0.41
Next, find P(X < 0.12).
(2 − 0) / 1 = (0.12 − 0) / x
2x = 0.12
x = 0.06
So the total probability is 0.41 + 0.06 = 0.47.
