The area of the rectangular field is 2c^3-c^2+6 square units. If the length of the field is c-2 units , what is the width ?
2 answers:
Answer:
2c² +3c +6 +18/(c -2)
Step-by-step explanation:
The area is the product of the length and width, so to find the width, you divide the area by the length. This can be done using <em>polynomial long division</em> (shown in the first attachment) or <em>synthetic division</em> (shown in the second attachment).
The width is: 2c² +3c +6 +18/(c -2).
___
Only the last step and the final result are shown for synthetic division. The previous steps are calculated exactly the same way. The number on the left is the root of the binomial you're dividing by (2, in this case).

Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Defective
Event B: From manufacturer A.
Probability a unit is defective:
2% of 43%(from manufacturer A)
1.5% of 57%(from manufacturer B). So
Probability a unit is defective and from manufacturer A:
2% of 43%. So
What is the probability that it came from manufacturer A?
0.5015 = 50.15% probability that it came from manufacturer A.
