Answer:

Step-by-step explanation:
Given
-- total
--- defective
--- selected
Required
The probability of rejecting the batch
This means that at least one of the selected piece is defected.
So, we first calculate the probability that all the selected piece are accepted.
So, we have:

The denominator decreases by 1 because it is a probability without replacement; 180 is subtracted from the numerator to represent the number of non-defective CDs
So, we have:


Using the complement rule, the probability that the batch will be rejected is:


X-45\x<-4(multiply both sides by X to remove the denominator )
X-45<-4x (collect the like terms)
-45<-4x+x
-45<-3x(divide both sides by -3
-45\-3<-3\-3x
15>x
A vertical line has no slope so the equation of the line is simply x = constant.
For this question we have:
x = 2
as the equation of the line.
Answer: x = 2
4 units left : subtract 4 from each x coordinate
3 units down : subtract 3 from each y coordinate
that is how i remember it
Answer:
y=-2x-3
Step-by-step explanation:
4x+2y=-6
2y=-6-4x
y=-6/2-4/2x
y=-3-2x
y=-2x-3
