The difference between the gas prices in 2013 and 2001 is 3.00
<h3>Graphing tool</h3>
See attachment for the graph of the line of best fit
<h3>The equation</h3>
Start by calculating the slope of the line of best fit using:
From the line of best fit, we have:
The regression equation is then represented as:
So, we have:
So, the linear regression equation is:
In 2001, the value of x is 1.
So, we have:
In 2013, the value of x is 13.
So, we have:
So, the difference (d) between the prices is:
Hence, the difference between the gas prices in 2013 and 2001 is 3.00

Answer:
b=22
Step-by-step explanation:
1 Remove parentheses.
b-11-29=-18b−11−29=−18
2 Simplify b-11-29b−11−29 to b-40b−40.
b-40=-18b−40=−18
3 Add 4040 to both sides.
b=-18+40b=−18+40
4 Simplify -18+40−18+40 to 2222.
b=22b=22
Remember foil and distributive property
note the invible -1
5a(2x-1)-1(8a-x)(2x-a)
look at first bit
5a(2x-a)=10ax-5a^2
2nd part
-1(8a-x)(2x-a)
-1(16ax-2x^2-8a^2+ax)
-1(17ax-2x^2-8a^2)
-17ax+2x^2+8a^2
now combine the 2 parts
10ax-5a^2-17ax+2x^2+8a^2
2x^2+3a^2-7ax
Answer:
1. There are a total of 19 marbles in the bag. The probability of picking a green marble out of them is 4/19 since there are only 4 green ones. The probability of picking a brown marble after replacing what has been initially picked is 1/19. The final probability is the product of the two probabilities and that is 4/361.
2. ?
3. 60%
Step-by-step explanation:
Balance sheet equation states that:
Assets, A = Liabilities, L + Equity, E => A=L+E
In the current case,
L = Long term debt + Current liabilities = $8,675+$1,865 = $10,540
E = $14,865
Therefore,
A = 14,865 +10,540 = $25,405
Now,
Current assets (excluding cash) = current liabilities+Net working capital, other than cash = $1,865+$2,315 = $4,180
Additionally,
A = Fixed assets+Current assets (excluding cash) + Cash
Therefore,
Cash = 25,405-20,660-4,180 = $565
