Answer:
the answer is A. One graph uses an open circle, but the other graph uses a closed circle. Also, the rays use arrows that point in opposite directions, but they have the same endpoint.
Answer:
the percentage change in the volume of the oil is -3.22%
Step-by-step explanation:
The computation of the percentage change in the volume of the oil is given below:
= -(6,000 - 0) ÷ (186,000)
= -3.22%
This negative sign represents the decrease in the volume
Hence, the percentage change in the volume of the oil is -3.22%
Answer:
Independent event
Step-by-step explanation:
Since the second and third spins do not depend on the results of the previous spins, this is an independent event.

Answer: (x+1)(x+3)</h3>
===================================================
Explanation:
Let's assume it factors into (x+a)(x+b)
The goal is to find the two numbers a and b.
FOIL out (x+a)(x+b) to get x^2+(a+b)x+ab
Note how a+b is the middle term and ab is the last term.
In the original expression, 4 is the middle term and 3 is the last term.
So we need to find two numbers that
There are two ways to multiply to 3 and they are
- 1 times 3 = 3
- -1 times -3 = -3
But only the first way has the factors add to 4. So that means a = 1 and b = 3.
Therefore (x+a)(x+b) = (x+1)(x+3)
And x^2+4x+3 = (x+1)(x+3)
