Answers

From the diagram given, line TR and RV are equal, using the obtained value of x, the value of the segment VS is 15 units

5x - 4 = 2x + 5

5x - 2x = 5 + 4

3x = 9

x = 9/3

x = 3

TS = VS

Hence, VS = 6x - 3

Substitute the value of x to obtain the value of VS :

VS = 6x - 3

VS = 6(3) - 3

VS = 18 - 3

VS = 15 units

Hence, the length of the segment VS is 15 units.

Assume a tax rate of 6.2% on $128,400 for Social Security and 1.45% for Medicare. No one will reach the maximum for FICA. Complete the following payroll register. (Use the percentage method to calculate FIT for this weekly period.)

Answers

Answer:

Claimed 4 allowances at a rate of $76.90 per allowance for weekly payroll.

Taxable income is therefore;

= 3,500 - (76.90 * 4 )

= $‭3,192.4‬0

Federal Income Tax (FIT).

With taxable income of $‭3,192.4‬0, Pat falls into the $3,073 to $4,597 bracket where tax is $565.15 plus 28% of anything above $‭3,073. Status is married.

= 565.15 + (28% * (‭3,192.4‬0 - 3,073))

= 565.15 + 33.43

= $‭598.58

Social Security

= Gross pay * 6.2%

= 3,500 * 6.2%

= $‭217‬

Medicare

= 3,500 * 1.45%

= $‭50.75‬

Net Pay

= 3,500 - 598.58 - 217 - 50.75

= $‭2,633.67‬

Step-by-step explanation:

John Doe, a super-genius student (known also under his nick-name Wile E. Coyote, super-genius) has just graduated from SPEA and found a job that will allow him to purchase a car to finally catch Roadrunner. He can either buy a new car at a cost of $22,000, buy a used car for $12000 or lease a new car for one year at a cost of $8,500 (assume total cash purchase up front, no financing or monthly payments required). The new car has a 20% chance of a serious break down resulting in a permanent impairment to the trade-in value. The trade-in value for the new car without a serious break down after one year is $18,000 but only $10,000 if the break down occurs. On the other hand, the used car has a 40% chance of suffering a major break down with a $8,000 decrease in the resale value. However, if it does not break down, Wile can sell it to a friend one year from now for $9,000 cash (assume he can also sell it to the friend for $4,000 if the breakdown occurs). Finally, the leased car has a 10% chance of breaking down with a repair cost of only $2,000, and if it doesn’t, Wile will not gain or lose anything by returning the car at the end of a one year lease period. NOTE: For the new and used car purchases all related repair costs resulting from a breakdown have been netted against the trade-in / resale value.
a. Construct a decision tree for Wile
b. What is the expected value of the new car?
c. What is the expected value of the used car?
d. What is the expected value of leasing the car?

Answers

Answer: See explanation

Step-by-step explanation:

a. Construct a decision tree for Wile

The solution to the question has been attached.

b. What is the expected value of the new car?

= [(0.2 × $10,000) + (0.8 × $18,000)] - $22,000

= $2000 + $14400 - $22000

= $16400 - $22000

= -$5600

c. What is the expected value of the used car?

= [(0.4 × $4000) + (0.6 ×$9000] - $12000

= $1600 + 5400 - $12000

= $7000 - $12000

= -$5000

d. What is the expected value of leasing the car?

= [(0.1 × -$2000) + (0.9 ×0)] - $8500

= -$200 - $8500

= -$8700

You have just opened a new nightclub, Russ' Techno Pitstop, but are unsure of how high to set the cover charge (entrance fee). One week you charged $7 per guest and averaged 345 guests per night. The next week you charged $10 per guest and averaged 300 guests per night.
(a) Find a linear demand equation showing the number of guests q per night as a function of the cover charge p. q(p) =

(b) Find the nightly revenue R as a function of the cover charge p. R(p) =

(c) The club will provide two free non-alcoholic drinks for each guest, costing the club $2 per head. In addition, the nightly overheads (rent, salaries, dancers, DJ, etc.) amount to $2,000. Find the cost C as a function of the cover charge p. C(p) =

(d) Now find the profit in terms of the cover charge p. P(p) = Determine the entrance fee you should charge for a maximum profit. p = $ per guest

Answers

(a) The number of guest per night=p,

and the cover charge for one night per person=q.

Let the liner demand equation be [tex]q(p)=mp+c\cdots(i)[/tex],

where m and c are constants.

Given that for the first week: q=345 and p=$7 and

for the second night: q=300 and p=$10.

Put these values in equation (i), we have

345=7m+c

[tex]\Rigntarrow c=345-7m\cdots(ii)[/tex]

and

300=10m+c

[tex]\Rightarrow 300=10m+(345-7m)[/tex] [from equation (ii)]

[tex]\Rightarrow 3m=-45[/tex]

[tex]\Rightarrow m=-15[/tex]

and from equation (ii),

[tex]c=345-7\times(-15)=450[/tex].

Hence, the required demand equation is:

[tex]q(p)=-15p+450\cdots(iii)[/tex]

(b) Revenue = (Number of guests) x (Cover charge)

R=qp

[tex]\Rightarrow R(p)=(-15p+450)p[/tex] [from equation (iii)]

[tex]\Rightarrow R(p)=-15p^2+450p\;\cdots(iv)[/tex]

(c) The costs per night for drinks for the number of guest p is  $2p and the nightly overheads is $2000.

So, the required cost function is

[tex]C(p)=2p+2000\;\cdots(v)[/tex]

(d) Profit=(Revenue)-(Total costs)

i.e [tex]P(p)=R(p)-C(p)[/tex]

Using equations (iv) and (v), we have

[tex]\Rightarrow P(p)=(-15p^2+450p)-(2p+2000)[/tex]

[tex]\Rightarrow P(p)=-15p^2+448p-2000.[/tex]

Now we have the profit function as function of cover charge (entry fee) per person.

So, to get the maximum profit, P, differentiate the profit function with respect to the cover charge, q and equate it to zero to get the eqtremum point.

[tex]\frac {dP}{dq}=0[/tex]

[tex]\Rightarrow -30p+448=0[/tex]

[tex]\Rightarrow p=14.93[/tex]

This point is either maxima or minima, so differentiate the profit function twice to to ensure the value of p corrosponding to what.

[tex]\frac {d^2P}{dq^2}=-30[/tex]

This the second deravitive is negative, so p=14.93 is the value for maximum profit.

Hence, for the maximum profit, the cover charge per guest is $14.93.

Every time you conduct a hypothesis test, there are four possible outcomes of your decision to reject or not reject the null hypothesis: (1) You don’t reject the null hypothesis when it is true, (2) you reject the null hypothesis when it is true, (3) you don’t reject the null hypothesis when it is false, and (4) you reject the null hypothesis when it is false.
Consider the following analogy: You are an airport security screener. For every passenger who passes through your security checkpoint, you must decide whether to select the passenger for further screening based on your assessment of whether he or she is carrying a weapon. Suppose your null hypothesis is that the passenger has a weapon. As in hypothesis testing, there are four possible outcomes of your decision: (1) You select the passenger for further inspection when the passenger has a weapon, (2) you allow the passenger to board her flight when the passenger has a weapon, (3) you select the passenger for further inspection when the passenger has no weapon, and (4) you allow the passenger to board her flight when the passenger has no weapon.
1. Which of the following outcomes corresponds to a Type I error?A. You allow the passenger to board his flight when the passenger has a weapon.B. You select the passenger for further inspection when the passenger has no weapon.C. You allow the passenger to board his flight when the passenger has no weapon.D. You select the passenger for further inspection when the passenger has a weapon.2. Which of the following outcomes corresponds to a Type II error?A. You allow the passenger to board his flight when the passenger has no weapon.B. You select the passenger for further inspection when the passenger has no weapon.C. You select the passenger for further inspection when the passenger has a weapon.D. You allow the passenger to board his flight when the passenger has a weapon.As a security screener, the worst error you can make is to allow the passenger to board his flight when the passenger has a weapon. The probability that you make this error, in our hypothesis testing analogy, is described by _____.

Answers

Answer:

1. A. You allow the passenger to board his flight when the passenger has a weapon.

2. B. You select the passenger for further inspection when the passenger has no weapon.

Explanation:

1. Remember, a Type I error in simple words means that the assumption "the passenger has a weapon" (null hypothesis) is actually true, but the airport security screener incorrectly concluded it is false. In other words, he assumed the passenger had no weapon and allowed the passenger to board his flight when he actually did have one.

2. While, a Type II error means that the assumption "the passenger has a weapon" (null hypothesis) is actually false, but the airport security screener incorrectly concluded it is true. In other words, he assumed the passenger had a weapon and selected the passenger for further inspection when he actually didn't have one.
