Answer:
The answer is in step-by-step explanation
Step-by-step explanation:
3 x + y + 3 z = 4
4 x - y + 2 z = 5
x - 2 y - z = 0
Use the identity:
P(A or B)=P(A)+P(B)-P(A and B)
Substitute given values,
0.88=0.62+0.47-P(A and B)
=>
P(A and B)=0.62+0.47-0.88=0.21

My favorite on-line calculator shows the same result.
Answer:
-12 / 17
Step-by-step explanation:
x | -1 | 2 | 5 | 8 |
-----------------------
y | 3 | -1 | -5 | -9 |
Piking the poits at the extreme:
x1 = - 1 ; y1 = 3
x2 = 8 ; y2 = - 9
Slope = Rise / Run
Rise = y2 - y1 = - 9 - 3 = - 12
Run = x2 - x1 = 8 - (-9) = 8 + 9 = 17
Hence,
Slope = - 12 / 17
