Answer:
x=8
y=1/6x+4/6
y= 2
Step-by-step explanation:
-2x + 18 =2
Move the constant to the right
-2x =2 - 18
Calculate the difference
-2x = -16
Divide both sides of the equation by -2
And that’s how I got x=8
The other one is x - 6y = -4
X= 6y - 4
Move the variable to the left hand side by adding it’s opposite to both sides
X - 6y = 6y - 4 - 6y
Since two opposites add up to zero,remove them from the expression
And that’s how x - 6y = -4

For the given functions f and g, find the requested composite function value.
f(x) = x - 8
x , g(x) = x2 + 6; Find ( g H f)(-2).
Answers
Answer:
106
Step-by-step explanation:
Composite function:
A composite function is represented by:
[tex](g \circ f)(x) = g(f(x))[/tex]
In this question:
[tex]f(x) = x - 8[/tex]
[tex]g(x) = x^2 + 6[/tex]
[tex](g \circ f)(x) = g(f(x)) = g(x-8) = (x-8)^2 + 6[/tex]
Find ( gof)(-2).
When x = -2. So
[tex](g \circ f)(-2) = (-2-8)^2 + 6 = (-10)^2 + 6 = 100 + 6 = 106[/tex]
The answer is 106.
The first step in analyzing a transaction is to determine:
O A. if the account balance will increase or decrease.
OB. the accounts that are involved.
O C. the type of accounts that are involved.
OD. which accounts are to be debited and credited.
Answers
Answer:
B. the accounts that are involved.
Step-by-step explanation:
Financial accounting is an accounting technique used for analyzing, summarizing and reporting of financial transactions like sales costs, purchase costs, payables and receivables of an organization using standard financial guidelines such as Generally Accepted Accounting Principles (GAAP). Examples of financial statements includes Balance sheet, cash-flow and income statement.
On the other hand, managerial accounting also known as cost accounting is an accounting technique focused on identification, measurement, analyzing, interpretation, and communication of financial information to managers for better decisions making and pursuit of the organization's goals.
The first step in analyzing a transaction is to determine the accounts that are involved. Since a company would have more than one transaction type, it is very important to determine what account is involved in the transaction process such as sales, purchase of inventory, payment of employee salaries and other types of expenses.
Researchers doing a study comparing time spent on social media and time spent on studying randomly sampled 200 students at a major university. They found that students in the sample spent an average of 2.3 hours per day on social media and an average of 1.8 hours per day on studying. If all the students at the university in fact spent 2.2 hours per day on studying, with a standard deviation of 2 hours, the sampling distribution of the time spent studying has approximate distribution
Answers
Answer:
The sampling distribution of the time spent studying has an approximately normal distribution, with mean 2.2 and standard deviation 0.1414.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Each student:
Mean of 2.2 hours, standard deviation of 2 hours.
Sampling distribution of the time spent studying has approximate distribution
Sample of 200.
By the Central Limit Theorem,
Approximately normal
Mean 2.2
Standard deviation [tex]s = \frac{2}{\sqrt{200}} = 0.1414[/tex]
The sampling distribution of the time spent studying has an approximately normal distribution, with mean 2.2 and standard deviation 0.1414.

2) 1) A 6 ft tall lawn ornament standing next to a baby elephant casts a 18 ft shadow. If the baby elephant casts a shadow that is 12 ft long, then how tall is it?
Answers
Answer: 4 feet.
Step-by-step explanation:
Proportion from lawn ornament to its shadow = 6ft : 18ft = 1 : 3
Proportion from baby elephant to its shadow = x : 12ft
These proportions have to be equal, because if it is the same time of day, the different object's shadows will have the same proportions.
In order to solve this problem, we need to cross multiply. (Attached image)
So, 3x = 12.
By solving this equation, we find that x = 4
The height of the baby elephant is 4 feet.

The probability of drawing a blue ball from Bag A is 1/5 and the
probability of drawing a red ball from Bag B is 2/3.
What is the probability of drawing a blue ball from Bag A AND a red
ball from Bag B?
Answers
Answer:
the probability of drawing a blue ball from bag A is 1/5 and the probability of drawing a red ball from bag B is 2/3.
The probability of drawing a blue ball from Bag A and a red ball from Bag B will be 2/15.
What is the definition of probability?
Probability denotes the likelihood of something happening. It is concerned with the occurrence of an unpredicted event.
Probability can only have a value between 0 and 1. Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of events is known as the favorable event ratio.
The probability of drawing a blue ball from Bag A is, 1/5
The probability of drawing a red ball from Bag B is, 2/3.
P(A)=1/5
P(B)=2/3
The probability of drawing a blue ball from Bag A and a red ball from Bag B will be;
P(A and B)=P(A). P(B)
P(A and B)=(1/5)×(2/3)
P(A and B)=(2/15)
Hence,the probability of drawing a blue ball from Bag A and a red ball from Bag B will be 2/15.

The time taken by Nick to do his statistics homework follows a normal distribution with a mean of 25 minutes and a standard deviation of 5 minutes. Jasmin’s homework time also follows a normal distribution with a mean of 50 minutes and a standard deviation of 10 minutes. They hate each other’s guts and never work together so we can assume that Nick’s homework completion is independent of Jasmine’s homework completion.
a) Define the random variable D to be the difference between the amount of time spent on a randomly selected assignment of Jasmin’s and a randomly selected assignment of Nick’s. So D = N – J. Find the mean and the standard deviation of D.
b) Calculate the probability that Nick spent longer doing his assignment than Jasmin did. Show your method clearly.
Answers
Answer:
a) Mean of D = -25
Standard deviation of D = 11.18
b) P(N > J ) = 0.9875
Step-by-step explanation:
Given - μₙ = 25, σₙ = 5 , μₐ = 50 , σₐ = 10
where μₙ is mean of nick and μₐ is mean of jasmine
σₙ = 5 is standard deviation of nick and σₐ is standard deviation of jasmine
To find - a) Define the random variable D to be the difference between the amount of time spent on a randomly selected assignment of Jasmine’s and a randomly selected assignment of Nick’s. So D = N – J. Find the mean and the standard deviation of D.
b) Calculate the probability that Nick spent longer doing his assignment than Jasmine did. Show your method clearly.
Proof -
a)
Mean of D = Mean of nick - Mean of jasmine
= 25 - 50 = -25
standard deviation of D = √Standard deviation of Nick + jasmine
= √5² + 10² = √25 + 100 = √125 = 11.18
∴ we get
Mean of D = -25
Standard deviation of D = 11.18
b)
We have to find - P(N > J)
If N > J , then D > 0
Now,
The z-score is expressed as
z = [tex]\frac{0 - (-25)}{11.18} = \frac{25}{11.18} = 2.24[/tex]
Now,
P(N>J) = P (D > 0) = P(Z < 2.24)
= 0.9875
⇒P(N > J ) = 0.9875
