Answer:
HOPE THIS HELPS
Step-by-step explanation:
The area = length * Width.
We know the width = X+6 inches and Area = x^3+3x^2–18x.
This problem can be solved just by dividing the area by width and we get a quotient as X^2–3x.
So the length is x^2–3x inches.
GCF means the term(s) that 6x and x have.
The GCF is x because:
1. Using multiplication: 6x * x = 6x^2
becomes x(6+x) = 6x^2
GCF is x.
Good luck to you!
Answer:
90 and 270 maybe neg 270
Step-by-step explanation:
What is the difference between selecting a member at random from a finite population and taking a simple random sample of size 1?
Solution: The correct option is d. There is no difference
<u>Explanation:</u>
Random sampling: In random sampling, each and every unit of the population has an equal chance of included in the sample.
Simple random sampling: In simple random sampling, also every unit of the population has an equal chance being included in the sample.
In the given situation, the selecting a member randomly from a finite population will be same as using a simple random sampling to select sample of size 1. Therefore, there is no difference between the two.
Answer: 1 hour
Step-by-step explanation:
Let distance1 = x km
Distance2 = 144 - x
Speed S1 = 63 kph
Speed S2 = 81 kph
Time = Distance / Speed
When the jets pass each other
(144-x) / 81 = x/63
63(144-x) = 81x
9072 - 63x = 81x
x = 9072 / 144
x = 63 km
Time = 63/63 = 1 hour
