2x + 2y + 1z = -5 ⇒ 2x + 2y + 1z = -5 ⇒ 4x + 4y + 2z = -10
3x + 4y + 2z = 0 ⇒ 3x + 4y + 2z = 0 ⇒ 3x + 4y + 2z = 0
1x + 3y + 2z = 1 x = -10
2x + 2y + 1z = -5
3x + 4y + 2z = 0 ⇒ 3x + 4y + 2z = 0
1x + 3y + 2z = 1 ⇒ 1x + 3y + 2z = 1
2x + y = -1
2x + y = -1
2(-10) + y = -1
-20 + y = -1
+ 20 + 20
y = 19
2x + 2y + z = -5
2(-10) + 2(19) + z = -5
-20 + 38 + z = -5
18 + z = -5
- 18 - 18
z = -23
(x, y, z) = (-10, 19, -23)
Answer:
The probability is 2/5.
Step-by-step explanation:
4/5 is the probability of not getting a 5
1/2 is the probability of flipping heads
4/5x1/2 = 4/10 = 2/5
Answer 7x^3 - 5x^2 + 6x -5
