Answer: 0.6
-------------------------------------------------------------------------------
To get this answer, subtract the given value (0.4) from 1 to get
1-0.4 = 0.6
The reason why this works is because the event either happens or it doesn't happen. There are no other options. So if
A = event happens
B = event doesn't happen
then P(A)+P(B) = 1 which leads to P(B) = 1-P(A)
Your answer in the sum is 0.26
3 - 2x + 5 < -4(x + 2)
-2x + 8 < -4(x + 2)
-2x + 8 < -4x - 8
-2x + 8 + 4x < -8
2x + 8 < -8
2x < -8 - 8
2x < -16
x < -16/2
x < -8
Answer: A) x < -8
You have to move the 8x over to the other side to get y by itself. and then divide the 4 from the y to the other side and y should equal y= 2x+5
