Answer:

Their duties are related, and their knowledge overlaps.

Explanation:

The Department of Labor of the United States, is the department that administers occupational safety, salary, working hours, etc. The department oversees the welfare of those who earn wages, seeking jobs, or retired people.

The Department of Labor grouped together the three separate occupations of plumbering, pipefitting, and steamfitting because their duties are somewhat related, and skills and knowledge intersect with each other.

The duties performed by plumbers, pipefitters, and steamfitters include installing of pipes, fixing pipes, inspection of pipelines and pipe systems, repairment of pipes, etc. And the knowledge of pipe of all three occupations is also similar. It includes pipe system design, safety, tool use, etc.

Thus the Department grouped them together because they have overlapping skills and knowledge, and similar duties. Therefore, the correct answer is the last option (D).

Marina CMI [18]

Answer:

Consider the following calculations

Explanation:

People end up tossing 12% of what they buy at the grocery store (Reader's Digest, March, 2009). Assume this is the true population proportion and that you plan to take a sample survey of 540 grocery shoppers to further investigate their behavior.

a- Show the sampling distribution of ( p¯ ), the proportion of groceries thrown out by your sample respondents

sampling distribution of ( p¯ ) is normal with

mean = 0.12 and

standard error = sqrt(p(1-p)/n) = sqrt(0.12*0.88/540) =0.0140

b- what is the probability that the sample proportion will be within ±.03 of the population proportion?

z value for 0.03 difference, z=0.03/0.014 =2.14

The required P= P( -2.14<z<2.14) = P( z <2.14) – P( z <-2.14)

=0.9838 - 0.0162

=0.9676

c- what is the probability that your survey will provide a sample proportion within ±.015 of the population proportion?

z value for 0.015 difference, z=0.015/0.014 =1.07

The required P= P( -1.07<z<1.07) = P( z <1.07) – P( z <-1.07)

=0.8577 - 0.1423

=0.7154

d- What would be the effect of taking a larger sample on the probabilities in parts (b) and (c)? Why?

Taking a larger sample will decrease the standard error. The probabilities in parts (b) and (c) will increase.

On January 1, Boston Company completed the following transactions (use a 7% annual interest rate for all transactions): (FV of $

GaryK [48]

Answer:

a) A sum of $6,000 is to be paid at the end of each year for 7 years and the principal amount $115,000 to be paid at the end of 7th year.

PV=$6,000/(1+0.07)^1 + $6,000/(1+0.07)^2 +$6,000/(1+0.07)^3 +$6,000/(1+0.07)^4 +$6,000/(1+0.07)^5 +$6,000/(1+0.07)^6 +$6,000/(1+0.07)^7 +$115,000/(1+0.07)^7

PV=$5,607.47 + $5,240.63 + $4,897.78 + $4,577.37 + $4,277.91 + $3,998.05 + $3,736.49 + $71,616.22

PV=$103,951.92

b) Let the single sum that will grow to $490,000 at 7% interest per annum at the end of 8 years be X

FV=PV(1+i)^n

$490,000 = X(1+0.07)^8

Thus,

X= $490,000/(1.07)^8

X = $490,000/1.7182

X = $285,182

Thhus, a single sum of $285,182 needs to be deposited for 8 years at 7% interest p.a.

The total amount of interest revenue is ($490,000-$285,182) = $204,818

c) PV = $75,000/(1.07)^1 + $112,500/(1.07)^2 + 150,000/(1.07)^3

PV = $70,093.45 + $98,261.85 + $122,444.68

= $290,800

FV =$75,000*(1.07)^1 + $112,500*(1.07)^2 + 150,000*(1.07)^3

= $80,250 + $85,867 + $91,878

= $257,995

d) The cost of the machine is $170,000. Immediate cash paid $34,000. Loan Amount is ($170,000-$34,000)=$136,000

The PVA factor at 7% p.a compounded annually for 5 years is 4.1002

Thus, the PMT = 136,000/4.1002

= $33,169

Thus, the amount of each annual payment is $33,169 for 5 years.

The total amount to be paid is ($34,000+$33,169*5)

=$34,000+$165845

=$199845

The interest expense is ($199845 - $170,000)

= $29,845

Jason purchased ABC stock at $40 per share and DEF stock at $35 per share on the same day in 2015. Exactly 6 months later, the A

Pachacha [2.7K]

Answer:

C) ABC 5% and DEF 5.7%

Explanation:

Data provided in the question:

Purchasing Cost of Stock ABC purchased = $40 per share

Purchasing Cost of Stock DEF purchased = $35 per share

Time = 6 months

Selling price of share of ABC = $42 per share

Selling price of DEF share = $36

Dividend paid to the DEF = $0.5 each quarter i.e $0.5 twice in 6 months

Thus,

Total dividend paid to DEF = $0.5 × 2

= $1

Now,

For ABC

Total return = Selling price - Purchasing Cost

= $42 - $40

= $2 per share

thus,

Holding period return = [ Total return ÷ Purchasing cost ] × 100%

= [ $2 ÷ $40 ] × 100%

= 5%

For DEF

Total return = Selling price + Dividend received - Purchasing Cost

= $36 + $1 - $35

= $2 per share

thus,

Holding period return = [ Total return ÷ Purchasing cost ] × 100%

= [ $2 ÷ $35 ] × 100%

= 5.7%

Hence,

option C) ABC 5% and DEF 5.7%.
