Answer:

The three scenarios are following

1- Murder at a house

2- Robbery in Bank

3- Road Accident

Explanation:

1- Murder at a house

When narrowing down the suspects of Murder, investigators will examine fingerprints and DNA to create a list of genetic qualities present. DNA analysis is based on locating similar patterns from a human sample and samples located at the crime scene. The time frame can be constructed by using measurements such as the temperature of the victim and the surrounding area

2- Robbery in Bank

Crime-scene investigators will gather data and then compare this information to existing databases to determine information such as the physical characteristics of a suspect. Examining the foot prints , investigators are able to determine how much a suspect weighs by comparing the depth of the print to a list of constants

3- Road Accident

Whether it is blood splatters, accident investigators are able to use mathematics to determine the trajectory of a falling object. Every object that is propelled through the air falls in an arc that can be measured to determine the speed and location from which the object began.

As part of the initial investment, Jackson contributes accounts receivable that had a balance of $32,290 in the accounts of a so
yuradex [85]

Answer: $30,923

Explanation:

From the question, we are told that as part of an initial investment, Jackson contributes accounts receivable that had a balance of $32,290 in the accounts of a sole proprietorship. Out of the amount, $1,367 is deemed completely worthless and for the remaining accounts, the partnership will establish a provision for possible future uncollectible accounts of $848.

The amount debited to accounts Receivable for the new partnership will be the difference between the account receivable balance and the amount that was deemed worthless. This will be:

= $32,290 - $1,367

= $30,923

Therefore, the amount debited to Accounts Receivable for the new partnership will be $30,923

You are saving for a Porsche Carrera Cabriolet, which currently sells for nearly half a million dollars. Your plan is to deposit
nordsb [41]

Answer:

a.) $217,298.44

b.) $253,514.84.

c.) $239,061.37 .

Explanation:

<u>a. Determine how much you will have saved after 10 years</u>

This is an ordinary annuity question and you are required to find the Future value (FV) at year 10. Using a financial calculator, key in the following inputs;

Total duration of investment; N = 10

Recurring payment; PMT = -15,000

Interest rate ; I/Y = 8%

PV = 0

then compute Future value;  CPT FV = 217,298.437

Therefore, in 10 years, you will have saved $217,298.44 which does not meet your goal of half a million dollars.

<u>b. Determine the amount saved if you were able to deposit $17, 500 each year.</u>

With the recurring payment increasing to 17,500 per year and the interest rate remaining at 8%, find the new Future value by keying in the following inputs;

Recurring payment; PMT = - 17,500

Interest rate ; I/Y = 8%

Total duration of investment; N = 10

PV = 0

then compute Future value;  CPT FV = 253,514.843

Therefore, in 10 years, you will have saved $253,514.84.

<u>c. Determine the amount saved if you deposit $15,000 each year, but with 10 percent interest.</u>

It is still an ordinary annuity question , however, the recurring payment(PMT) will be 15,000 as before but with an annual interest rate(I/Y) of 10%.  Using a financial calculator, key in the following inputs;

Total duration of investment; N = 10

Recurring payment; PMT = -15,000

Interest rate ; I/Y = 10%

PV = 0

then compute Future value;  CPT FV = 239,061.369

Therefore, in 10 years, you will have saved $239,061.37 .

A production center is available for 8 hours per day in a factory. It is comprised of several rotary parts, and the worker opera
cricket20 [7]

Answer:

75%

Explanation:

Since the production center is available for 8 hours per day in a factory, and the worker operating it is required to lubricate these rotary parts once each day.

If it takes 2 hours to remove these parts from the equipment, lubricate them, and re-assemble them and the production center is not available for production during these times;

Then the availability of the production center is 75% which is derived by : [8 hours total - 2 hours downtime / 8 hours total availability] x 100 = 75%

uppose you buy a bond with a coupon of 7.8 percent today for $1,080. The bond has 5 years to maturity. Assume interest payments
Mariulka [41]

Answer:

45.58%

Explanation:

Rate of return is the expected gain or loss on an investment, over a specific time period. It is derived as a percentage of the investment's original value or cost.

ROR = [CV - IV]/ IV × 100

CV is the current value of the investment (value at the end of the investment period)

IV is the initial value of the investment.

Note also, the assumption that interest payments are reinvested.

At the end of year 1, interest payment is $1,164.24

End of year 2 - $1,255.05

End of year 3 - $1,352.95

End of year 4 - $1,458.48

End of year 5 - $1,572.24

[Interest rate - 7.8%]

ROR = (1572.24 - 1080)/1080 × 100

ROR = 45.58%
