Answer:
P(A or B) = P(A) + P(B) - P(A and B)
0.87 = 0.8 + P(B) - 0.23
0.87 = P(B) + 0.57
P(B) + 0.57 = 0.87
P(B) + 0.57-0.57 = 0.87-0.57
P(B) = 0.3
Answer: 0.3
Answer:
The answer to your question is the last choice
Step-by-step explanation:
![(4z^{8})^{-3}](https://tex.z-dn.net/?f=%284z%5E%7B8%7D%29%5E%7B-3%7D)
Process
1.- Use the exponent law "Power"
![4^{-3} z^{(8)(-3)}](https://tex.z-dn.net/?f=4%5E%7B-3%7D%20z%5E%7B%288%29%28-3%29%7D)
2.- Simplify
![4^{-3} z^{-24}](https://tex.z-dn.net/?f=4%5E%7B-3%7D%20z%5E%7B-24%7D)
3.- Use the exponent law "Negative exponent"
![\frac{1}{4^{3} z^{24}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%5E%7B3%7D%20z%5E%7B24%7D%7D)
![\frac{1}{64z^{24}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B64z%5E%7B24%7D%7D)
4.- Conclusion
He should have applied the exponent -3 to 4 to get
(-3, 7)
Explanation: the point (-5,8) moves to the left (x axis) 2 points and down (y axis) 1 point. Thus -5 + 2 = -3 and 8 - 1 = 7, so the answer is (-3, 7)
The last one is the only one that will work.
For the first one the y intercept is when x = 0. The point would be 0,4
The second one gives a point of (4,0)
The third one is nonsense. (4,4) is not on this line.
