Edwin Edwards and Karen Davis owned EEE, Inc., which owned three convenience stores, all of which sold gasoline. Reid Ellis delivered to the three convenience stores $26,675.02 worth of gasoline for which he was not paid. Ellis proved that Edwards and Davis owned the business, ran it, and in fact personally ordered the gasoline. He claimed that they were personally liable for the debt owed him by EEE, Inc. Decide. [Ellis v.
Edwards, 348 S.E.2d 764 (Ga. App.)]
Question Completion:
Note: This is a Law question, not Mathematics.
Answer:
Decision:
Edwards and Davis are not personally liable for the debts of EEE, Inc.
Step-by-step explanation:
That Edwin Edwards and Karen Davis owned EEE Inc. does not force them to be personally liable for the debts of EEE Inc. EEE Inc. is a separate legal entity. There is the legal separation of ownership and the liabilities of Edwards and Davis are limited to the capital they contributed or undertook to contribute to the corporation. The corporate veil is only lifted when it is ascertained that EEE Inc. was not run as a legal entity separate from the owners. We can also conclude that there is no evidence of abuse of the corporate form of EEE Inc. with comingling of assets or for the purpose of promoting fraud or injustice or evasion of tort or contractual responsibility on the part of Edwards and Davis. Therefore, Edwin Edwards and Karen Davis are not personally liable for the debts of EEE Inc. as claimed by Reid Ellis.

Answer:
x=33
Step-by-step explanation:
The angles have to add up to 180, so you get:
2x - 18 + 4x = 180
6x = 180 + 18
x = 198/6
x = 33
The local authorities in a certain city install 10,000 electric lamps in the streets of the city. If these lamps have an average life of 1000 burning hours with a standard deviation of 200 hours, assuming normal distribution, what number of lights might expected
Step-by-step explanation:
It is given:
[tex]\mu=1000[/tex], [tex]\sigma=200[/tex]
Let x be the random variable that denotes the number of hours the lamp lights up.
what number of lights might expected to fail in the first 800 burning hours
Answer: We are required to find the expected number of lights to fail in the first 800 burning hours.
First, we have to find the probability as:
P(Z < 800)
Using the z-score formula, we have:
Using the z-score formula, we have:
[tex]P(x <800)=P \left(z<\frac{800-1000}{200} \right )[/tex]
=P(z<-1)
Now using the standard normal table, we have:
P(x<800)=P(z<-1)=0.1587
Therefore, the expected number of lights to fail in the first 800 burning hours is:
[tex]\boldsymbol{0.1587 \times 10000=1587}[/tex]
After how many burning hours 10% of the lamps would be still burning?
We first need to find the z-value corresponding to area = 1- 0.10 = 0.90. Using the standard normal table, we have:
z(0.90)=1.28
Now using the z-score formula, we have:
[tex]z= \frac{x-\mu}{\sigma}[/tex]
[tex]1.28= \frac{x-1000}{200}[/tex]
[tex]1.28 \times 200= x-1000[/tex]
[tex]256= x-1000[/tex]
x= 1000+256
[tex]\boldsymbol{x= 1256 }[/tex]
Using the Zscore principle, the number of bulbs expected to Fail in the first 800 burning hours is 1587
Given the Parameters :
σ = 200μ = 1000x = 800The number of Lamps that might be expected to fail in the first 800 burning hours :
Recall:
Zscore = (x - μ) ÷ σZscore = (800 - 1000) / 200 = -1
Using the normal distribution table :
P(Z < -1) = 0.15866
The number of bulbs expected to fail :
P × total number of bulbs0.15866 × 10000 = 1586.6
Hence, 1587 bulbs are expected to fail in the first 800 burning hours.

as a graded class activity, your teacher asks your class to reflect a triangle across the y-axis and then across the x-axis. Your classmate gets upset because he reversed the order of these reflections and thinks he will have to start over. What can you say to your classmate to help him?
Answer:
Both processes will yield same results and he need not worry
Step-by-step explanation:
Let us firstly check if we will have same results on both steps
y before x
Let us have the point (x,y) on the triangle
y reflection
(-x,y)
then x reflection
(-x,-y)
Let us now get the order in which my friend followed
x reflection

Suppose that 7 in every 10 auto accidents involve a single vehicle. If 15 auto accidents are randomly selected, compute the probability that at most 4 of them involve a single vehicle.
Answer:
[tex]\mathbf{P(X \le 4 ) \simeq 0.0006722}[/tex]
Step-by-step explanation:
From the information given:
p = x/n
p = 7/10
p = 0.7
sample size n = 15
Suppose X be the number of accidents involved by a single-vehicle.
Then;
[tex]X \sim Binom (15,0.7)[/tex]
Thus, the required probability that at most 4 involve in a single-vehicle is
[tex]P(X\le 4) \\ \\P(X \le 4) = P(X = 0) + P(X =1 ) + ... + P(X = 4)[/tex]
[tex]P(X \le 4 ) = (^{15}_0) *0.7^0 *0.3^{15-0} + (^{15}_1) *0.7^1 *0.3^{15-1} + (^{15}_2) *0.7^2 *0.3^{15-2} + (^{15}_3) *0.7^3 *0.3^{15-3} + (^{15}_4) *0.7^4 *0.3^{15-4}[/tex]
[tex]P(X \le 4 ) = (\dfrac{15!}{0!(15-0)!}) *0.7^0 *0.3^{15-0} + (\dfrac{15!}{1!(15-1)!}) *0.7^1 *0.3^{15-1} + (\dfrac{15!}{2!(15-2)!}) *0.7^2 *0.3^{15-2} + (\dfrac{15!}{3!(15-3)!}) *0.7^3 *0.3^{15-3} + (\dfrac{15!}{4!(15-4)!}) *0.7^4 *0.3^{15-4}[/tex]
[tex]P(X \le 4 ) =1.4348907 \times 10^{-8} +5.02211745 \times 10^{-7} + 8.20279183 \times 10^{-6} + 8.29393397 \times 10^{-5} + 5.80575378 \times 10^{-4}[/tex]

The elves and reindeer are getting ready for a meeting with Santa.
So far 14 of them have arrived.
If they have 38 legs between them, how many reindeer are at the meeting and how many elves are at the meeting?
Let [tex]e[/tex] and [tex]r[/tex] be the number of elves and reindeers, respectively.
We know that:
[tex]r+e=14[/tex] (so far 14 of them have arrived)
[tex]4r+2e = 38[/tex](each reindeer has 4 legs and each elf has two)
If we multiply the first equation by 2 we have [tex]2r+2e=28[/tex], and if we subtract this equation from the second we have [tex]2r=10[/tex] which implies [tex]r=5[/tex].
So, there are 5 reindeers and 9 elves (remember that they have to sum up to 14).
The number of reindeers is 5 and the number of elves is 9.
Two equations can be derived from the equation:
e + r = 14 equation 1
2e + 4r = 38 equation 2
Where:
e = number of elves at the meeting
r = number of reindeers at the meeting
In order to determine the value of r, multiply equation 1 by 2.
2e + 2r = 28 equation 3
Subtract equation 3 from 2
2r = 10
Divide both sides of the equation by 2
r = 5
To solve for e substitute for r in equation 1
5 + e = 14
e = 14 - 5
e = 9

What is the probability of the outcome being an A?
Answer:
The probability of the outcome being an A is 1/2.
Step-by-step explanation:
[tex]\frac{1}{2}[/tex] probability of the outcome being an A, option D.
---------------------------------------------
A probability is the number of desired outcomes divided by the number of total outcomes.
The spinner is divided into 8 regions, thus, there are 8 total outcomes.4 of those regions are A, so there are 4 desired outcomes.---------------------------------------------
The probability of the outcome being an A is:
[tex]p = \frac{4}{8} = \frac{1}{2}[/tex]
Thus:
[tex]\frac{1}{2}[/tex] probability of the outcome being an A, option D.

When reaching mile marker 7 on a trail, Natalie uses her GPS to find that her current elevation is 6350 feet. If she follows the trail until its end at mile marker 12, her elevation will be 8720 feet. What is the average change in elevation of Natalie’s position from mile marker 7 to mile marker 12, in feet per mile marker?
Find the difference in elevations:
8720 - 6350 = 2370 feet.
Difference in mile markers: 12-7 = 5
Average change = feet / markers
2370/5 = 474
The answer is 474 feet
