Answer:
n=2
Step-by-step explanation:
subtract 4n - 2n
2n=4
divide by 2 to get rid of the two on the n side
n=2
The value of n in the equation 4n - 2n = 4 is n = 2.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
To find the value of n in the equation 4n - 2n = 4, combine like terms on the left side of the equation:
4n - 2n = 4
(4 - 2)n = 4
2n = 4
To isolate n, we divide both sides of the equation by 2:
2n/2 = 4/2
n = 2
Therefore, the value of n in the equation 4n - 2n = 4 is n = 2.

1. You work for a mortgage lender that really encourages you to sell ARM loans to your clients. In fact, if 75% of the loans you close each month are ARM loans, you receive a very nice bonus. You have a customer on the phone that you don’t feel understands ARM loans very well despite all your efforts. He tells you repeatedly that he would be better off with a 30-year fixed rate mortgage. You proceed to take his application and send all the required documentation to him for a 5/1 ARM. He signs the documents and returns them to you. You process his loan and close it 30 days later.
A. Do you feel you ethically assisted your borrower with this loan?
B. What could you have done differently?
2. You have a co-worker at work that you are also friends with. One day, a borrower comes in and meets with him. You overhear the borrower tell your co-worker that he has a loan with his mom and dad for about $10,000 that he pays $300 a month. Your co-worker proceeds as if he didn’t hear your borrower at all. Once he has taken the application, he tells the borrower that he qualifies for maximum financing for a $250,000 home. However, that does not take into consideration the $300 a month the borrower pays his parents for the loan.
A. Did your coworker do anything unethical in this transaction?
B. Assuming you feel this was an unethical situation, how do you handle this?
Answer:
A
Well in this case i don't feel i have ethically assisted by borrower because the type of loan my costumer requested from me is the 30-year fixed rate mortgage but because of the bonus i will gain from closing ARM loan i sent him/her the documentation to him for a 5/1 ARM loan even though he has told me repeatedly that he would be better off with the 30-year fixed rate mortgage
B
What i would have done differently was to be more patient and explain him the benefits of the ARM loan and the if he / she insists that he still want the 30-year fixed rate mortgage, then i would have sent him /her the documentation for the 30-year fixed rate mortgage.
2
A
Yes my co-worker acted in an unethical manner by not recognizing the fact that the costumer is servicing another loan with $300 a month and then proceeding to qualify him/her for a maximum financing of $250,000 which will would increase the risk in the current transaction
B
Since i feel this is unethical, the next step i will take is to call my co-worker aside and bring to his notice the fact that the borrower is servicing another loan with $300 per month , and then i will ask my co-worker to bring this fact into consideration when determine his maximum financing which in this case he has to reduce , then if my co-worker does not agree with my advice then in order to ensure that the company does not loss funds i will call in a higher authority in the company.
Step-by-step explanation:
CIO and MAP are
supplementary MAP measures five times the other angle. What is the complement of the smaller anglo?
Provide the equation to solve for the unknown angle
Measure of Angle CIO
MAP
Complement of smaller angle
Answer:
Measure of CIO = 30°
Measure of MAP = 150°
Complement of smaller angle = 60°
Step-by-step explanation:
Given that <CIO and <MAP are supplementary, therefore:
m<CIO + m<MAP = 180°
Let x be m<CIO
m<MAP = 5x
Thus:
x + 5x = 180
Solve for x
6x = 180
Divide both sides by 6
x = 30°
The smaller angle = m<CIO = x = 30°
The bigger angle = m<MAP) = 5x = 5(30) = 150°
Complement of the smaller angle = 90 - 30 = 60°

Nielsen has found that traditional television viewing habits vary based on the age of the consumer as an increasing number of people consume media through streaming devices (Nielsen website). The following data represent the weekly traditional TV viewing hours in for a sample of people aged and people aged .
Viewers aged 18–34 24.2 21.0 17.8 19.6 23.4 19.1 14.6 27.1 19.2 18.3
22.9 23.4 17.3 20.5
Viewers aged 35–49 24.9 34.9 35.8 31.9 35.4 29.9 30.9 36.7 36.2 33.8
29.5 30.8
Required:
a. Compute the mean and median weekly hours of traditional TV viewed by those aged 18–34.
b. Compute the mean and median weekly hours of traditional TV viewed by those aged 35–49.
c. Compare the mean and median viewing hours for each age group. Which group watches more traditional TV per week?
Answer:
Step-by-step explanation:
a) Mean = sum of variables/sample size
For Viewers aged 18-34
Data given
24.2 21.0 17.8 19.6 23.4 19.1 14.6 27.1 19.2 18.3
22.9 23.4 17.3 20.5
Sum of variables = 34+24.2+21.0+17.8+19.6+23.4+19.1+14.6+27.1+19.2+18.3 +22.9+23.4+17.3+20.5
= 288.4
Sample size = 14
Mean = 288.4/14
Mean = 20.6
Median is the value at the middle of the data after rearranging either ascending or descending order.
On re arranging
14.6, 17.3, 17.8, 18.3, 19.1, 19.2, )19.6, 20.5, (21.0, 22.9, 23.4, 23.4, 24.2, 27.1
Based on the arrangement it can be seen that the value at the middle is 20.5 and 19.6 so we will take the average of the values.
Median = 19.6+20.5/2
Median = 20.05
hence the median value is 20.05
b) For Viewers aged 35-49
Data given
24.9 34.9 35.8 31.9 35.4 29.9 30.9 36.7 36.2 33.8
29.5 30.8
Sum of variables = 24.9+34.9+35.8+31.9+35.4+29.9+30.9+36.7+36.2+33.8 +29.5+30.8
= 390.7
Sample size = 12
Mean = 390.7/12
Mean = 32.56
Median is the value at the middle of the data after rearranging either ascending or descending order.
On re arranging
24.9, 29.5, 29.9, 30.8, 30.9), 31.9, 33.8, (34.9, 35.4, 35.8, 36.2, 36.7
Based on the arrangement it can be seen that the value at the middle is 31.9 and 33.8. Taking the average vale;
Median = 31.9+33.8/2
median = 32.85
Hence the median of the data is 32.85
c) Based on both means, the mean value of the people between ages 35-49 is grater than that of ages 18-34. This shows that the people under age of 35-49 watches more traditional TV per week and due is due to the greater mean value they possess.
The median value of the people between ages 35-49 is also grater than that of 18-34 by 12.8 (32.85-20.05)

You may have polarized sunglasses that eliminate glare by polarizing the light. When light is polarized, all of the waves are traveling in parallel planes. Suppose vertically polarized light with intensity Io strikes a polarized filter with its axis at an angle of θ with the vertical. The intensity of the transmitted light It and θ are related by the equation Cosθ= √ Io/It. If θ, write It as a function of Io,
Answer:
lt = lo/cos²θStep-by-step explanation:
Given the intensity of the transmitted light It and θ are related by the equation Cosθ= √ Io/It, we are to write lt as a function of lo
Given the equation
Cosθ= √ Io/It
Let us make lt the subject of the formula;
square both sides of the equation
(Cosθ)²= (√ Io/It)²
cos²θ = lo/lt
cross multiply
ltcos²θ = lo
divide both sides by cos²θ
ltcos²θ/ cos²θ= lo/cos²θ
lt = lo/cos²θ
Hence the expression of lt as a function of lo is lt = lo/cos²θ
Almost all companies utilize some type of year-end performance review for their employees. Human Resources (HR) at the University of Texas Health Science Center provides guidelines for supervisors rating their subordinates. For example, raters are advised to examine their ratings for a tendency to be either too lenient or too harsh. According to HR, "if you have this tendency, consider using a normal distribution—10% of employees (rated) exemplary, 20% distinguished, 40% competent, 20% marginal, and 10% unacceptable." Suppose you are rating an employee’s performance on a scale of 1 (lowest) to 100 (highest). Also, assume the ratings follow a normal distribution with a mean of 50 and a standard deviation of 15.
a. What is the lowest rating you should give to an "exemplary" employee if you follow the University of Texas HR guidelines?
b. What is the lowest rating you should give to a "competent" employee if you follow the University of Texas HR guidelines?
Answer and Step-by-step explanation:
Solution:
Given:
µ = 50
∂ = 15
Lowest rating given to exemplary.
The top 10 %of the employees are related exemplary:
P(x > L) = 10 % =0.10
The average probability table in the appendix contains the only probability of the form.
P (0 < x< L ) = p ( x > 0 ) – P ( x > L )
= 0.5 -0.10
= 0.40
z- Score in the normal probability table in the appendix corresponding to a probability of 0.40 or the closest probability.
Z = 1.28
The standardized score is the value x decreased by the mean and then divided by the standard deviation.
Z = x - µ / σ
L = x = µ +z0
= 50 + 1.28(15)
= 69.2
Lowest rating giving to competent:
The lower boundary of competent is boundary of bottom 30%
P(x < L ) = 30% = 0.30
The normal probability table contains only probability of the form p( 0≤z≤z0)
P( 0< x < -L) = P(L < x < 0)
= p(x < 0) – p(x < L)
=0.5 – 0.30
= 0.20
Z score in normal probability corresponding to the probability of 0.20
-z = 0.52
Z= - 0.52
Value x decreased by the mean and divide by standard deviation:
Z = x - µ / ∂
L = x = µ + zo
= 50 – 0.52(15)
= 42.2

Answer:
Kindly check explanation
Step-by-step explanation:
Given the data below :
x : 89.3 68.6 32.7 37.3 39.7 46.7 66.1 79.4 66.4 52.1 47.3 64.4 53.7 63.4 46.2 63.0 92.1 57.6
Mean(m) = ΣX / n
ΣX = 1066 ; n = number of observations = 18
Mean(m) = 1066 / 18
Mean = 59.22
Standard deviation (σ) :
Using the online standard deviation calculator :
σ = √(Σ(x - m)²/n-1)
σ = √264.198395
σ = 16.72
The mean amount poured into a glass for the 18 samples is 59.22 while the variation in the data samples from the mean value is 16.72.
typical amount poured into a short, wide glass is 19.7 mL. A typical deviation from the mean amount poured is_____mL.
(59.22 - 19.7) mL = 39.52mL
Mean amount poured into a tall slender glass = 51.283
Mean (short wide glass) = 59.22mL
Mean (tall slender glass) = 51.283mL
Short wide glass > tall slender glass

Within a company is a (micro)economy that is monitored by the accounting procedures. In terms of the accounts, the various departments "produce" costs, some of which are internal and some of which are direct costs. This problem shows how an open Leontief model can be used to determine departmental costs.
The sales department of an auto dealership charges 10% of its total monthly costs to the service department, and the service department charges 20% of its total monthly costs to the sales department. During a given month, the direct costs are $88,200 for sales and $29,400 for service. Find the total costs (in dollars) of each department. (Round your answers to the nearest whole number.)
sales department
service department
Answer:
The total cost of sales department is [tex]a = \$ 84,000[/tex]
The total cost of services department is [tex]b = \$ 21,000[/tex]
Step-by-step explanation:
From the question we are told that
The direct for sales cost is [tex]SC = \$88,200[/tex]
The direct cost for service department is [tex] SV = \$29,400[/tex]
Given that the sales department charges 10% of its total monthly costs to the service department
The indirect cost of service department is 10% of a = 0.10 a
Here a is the total cost of sales
Given that the service department charges 20% of its total monthly costs to the sales department
The indirect cost of sales department is 20% of b = 0.20 b
Here b is the total cost for service department
Generally the direct cost of sales can be mathematically represented as
[tex]SC = a + 0.20b [/tex]
=> [tex]88200 = a + 0.20b[/tex]
=> [tex]a = 88200-0.20b[/tex]
Generally the direct cost of services can be mathematically represented as
[tex]SV = b + 0.10a [/tex]
=> [tex]29400 = b + 0.10a[/tex]
substituting for a in the above equation
=> [tex]29400 = b + 0.10 [88200-0.20b][/tex]
=> [tex]b = \$ 21,000[/tex]
substituting this value into the equation for a
[tex]a = 88200-0.20 (21000)[/tex]
=> [tex]a = \$ 84000[/tex]
Can we conclude that x - 5 is a factor of the polynomial
x^3 − x^2 − 17x − 15
How do you know?
Answer:
use synthetic division
Step-by-step explanation:
use synthetic division to solve [tex]\frac{x^{3}-x^{2} -17x-15}{x-5}[/tex].
if solved correctly, you should get [tex]x^{2} +4x+3[/tex] with no remainder.
because there is no remainder, x-5 is a factor of the polynomial given.
[tex](x-5)[/tex] is a factor of the given polynomial because the value of the polynomial is [tex]0[/tex] at [tex]x=5[/tex].
Given:
The given polynomial is [tex]x^3-x^2-17x-15[/tex].
Explanation:
We know that, [tex](x-c)[/tex] is a factor of [tex]P(x)[/tex] if and only if [tex]f(c)=0[/tex].
We have,
[tex]P(x)=x^3-x^2-17x-15[/tex]
Substituting [tex]x=5[/tex] in the above polynomial, we get
[tex]P(5)=(5)^3-(5)^2-17(5)-15[/tex]
[tex]P(5)=125-25-85-15[/tex]
[tex]P(5)=0[/tex]
Since [tex]P(5)=0[/tex], therefore [tex](x-5)[/tex] is a factor of the given polynomial.

Use the graph of the function. Determine over what interval(s) the function is positive or negative.
Answer:
The function is positive
Step-by-step explanation:
As you can see, the line makes a U shape aiming for the positive side of the graph.
The function in which the function is positive is (- 2, -1] ∪ [1, 2) and negative is [-1 to 1].
We have a graph of a function f(x).
We have to determine over what interval the function is positive or negative.
Define Function.A function from a set X to a set Y is an assignment of an element of Y to each element of X. The set X is called the domain of the function and the set Y is called the codomain of the function. For example - shown below is a piecewise function -
[tex]f(x) = \left\{ \begin{array}{ll} x^2 \quad x > 0 \\ 0 \quad \text{else} \end{array} \right.[/tex]
According to the question, we have a graph.
It can be seen in graph that the function f(x) is '+' in ranges : - 2 to -1 and 1 to 2.
The interval in which f(x) is positive is → (- 2, -1] ∪ [1, 2).
In the interval of : -1 to 1, the function has a negative value.
The interval is → [-1 to 1]
Hence, the function in which the function is positive is (- 2, -1] ∪ [1, 2) and negative is [-1 to 1].
