The same amount of principal is invested in different accounts earning the same interest rate. Which of the following
accounts would have the greatest accumulated value at the end of one year?
a. An account earning no interest
b. An account earning simple interest
C. An account earning interest compounded annually
d. An account earning interest compounded daily
Please select the best answer from the choices provided
.
А A
OB
С
D
Answer:
d. An account earning interest compounded daily
Step-by-step explanation:
An account earning interest compounded daily will have the greatest accumulated value at the end of one year.
Compound interest provides a higher return on value compared to simple interest even much more so when it is done daily.
Compound interest is an interest accrued on the principal and subsequent interest on capital. Simple interest is simply interest on the capital alone. The time duration plays an important role. A principal compounded daily at a certain rate will yield more value at the end of a year than one compounded weekly, monthly, quarterly or annually.Therefore, an account earning interest compounded daily will give a better return of value.

g Consider writing onto a computer disk and then sending it through a certifier that counts the number of missing pulses. Suppose this number X has a Poisson distribution with lamda = .2. a) What is the probability that a disk has exactly one missing pulse? b) What is the probability that a disk has at least two missing pulses? c) What is EX
Answer:
a) P(1) = 0.1637
b) \(P(x\geq 2) = 0.0176\)
c) E(x) = 0.2
Step-by-step explanation:
If X follows a poisson distribution, the probability that a disk has exactly x missing pulses is:
\(P(x)=\frac{e^{-m}*m^x}{x!}\)
Where m is the mean and it is equal to the value of lambda. So, replacing the value of m by 0.2, we get that the probability that a disk has exactly one missing pulse is equal to:
\(P(1)=\frac{e^{-0.2}*0.2^1}{1!}=0.1637\)
Additionally, the probability that a disk has at least two missing pulses can be calculated as:
\(P(x\geq 2)=1-P(x<2)\)
Where \(P(x<2)=P(0)+P(1)\).
Then, \(P(0)\) and \(P(x\geq 2)\) are calculated as:
\(P(0)=\frac{e^{-0.2}*0.2^0}{0!}=0.8187\\P(x\geq 2) = 1 - (0.8187 + 0.1637)\\P(x\geq 2) = 0.0176\)
Finally, In the poisson distribution, E(x) is equal to lambda. So E(x) = 0.2
Dingaka receives R12650R12650 when taking out a loan with an annual simple discount rate of 12,5%12,5%. The loan has to be repaid in eight months’ time. The amount that he has to repay is?
Dingaka took out a loan of R12650 with a simple annual discount rate of 12.5%. He has to repay R11595.83 in eight months, after deducting the simple discount of R1054.17.
To find the amount that Dingaka has to repay, we can use the formula for simple discount
Simple Discount = Principal * Rate * Time
Where Principal is the original amount borrowed, Rate is the annual simple discount rate, and Time is the time period in years.
We know that Dingaka received R12650 as the principal amount and the annual simple discount rate is 12.5%, which is equivalent to 0.125 as a decimal. The time period is 8/12 = 2/3 years, since the loan has to be repaid in eight months' time.
Plugging these values into the formula, we get
Simple Discount = 12650 * 0.125 * 2/3
= 12650 * 0.08333333
= 1054.166625
Therefore, the amount that Dingaka has to repay is the principal minus the simple discount, which is
Amount to Repay = Principal - Simple Discount
= 12650 - 1054.166625
= 11595.833375
So, Dingaka has to repay R11595.83 after eight months.

Heritage Company uses a job-order costing system to assign costs to jobs. It had no work in process or finished goods inventories on hand at the beginning of May. The table below provides data concerning the only three jobs worked on in May.
Job X Job Y Job Z
Direct labor hours 200 80 120
Direct materials $ 4,800 $ 1,800 $ 3,600
Direct labor $ 2,400 $ 1,000 $ 1,500
Jobs X and Y were completed in May; however, only 150 of the 200 units included in Job X were sold in May, whereas all 100 of Job Y’s units were sold in May. Job Z was not completed by the end of the month.
Overhead costs are applied to jobs based on direct labor-hours and the predetermined overhead rate is $45 per direct labor-hour. The company’s total applied overhead always equals its total actual overhead.
Required:
Compute the amount of overhead cost that would have been applied to each job during May.
Compute the work in process inventory that would be reported in the company’s May 31 balance sheet.
Compute the finished goods inventory that would be reported in the company’s May 31 balance sheet.
Compute the cost of goods sold that would be reported in the company’s income statement for May.
a) The amount of overhead cost that would have been applied to each job during May, based on the predetermined overhead rate, was as follows:
Job X Job Y Job Z
Overhead applied $9,000 $3,600 $5,400
b) The work-in-process inventory reported in the company's May 31 balance sheet was $10,500 for Job Z only.
c) The finished goods inventory that would be reported in the company’s May 31 balance sheet was $4,050.

Construct an equation that has k = 4 as its solution. Use k on both sides of the equation.
______=______
\(\frac{3}{2}k - 7 = \frac{k}{4} - 2\)
Since our fractions have two different denominators of 2 and 4 in this equation, we can get rid of the fractions by multiplying both sides of the equation by their common denominator, which is 4.
So we have \((4)(\frac{3}{2}k - 7) = (\frac{k}{4} - 2)(4)\).
Make sure you distribute the 4 through both
terms on both sides of the equation.
On the left, (4)(3/2k) is 6k and (4)(-7) is -28.
On the right, (4)(k/4) is k and (4)(-2) is -8.
So we have 6k - 28 = k - 8.
Now subtract k from both sides to get 5k - 28 = -8.
Now add 28 to both sides to get 5k = 20.
Finally, dividing both sides by 5, we find that k = 4.

The initial amount and the amount after 40 hours of the radioactive substance Uranium is 4300grams and 593.4grams respectively.
Some heavy elements like uranium and thorium are unstable in nature, they disintegrates constantly to become more stable by emitting certain particles, this property of such compounds is called Radioactivity and that substance is said to be Radioactive.
The half life of Uranium-240 has amount A left after t hours given by
A(t) = 4300(1/2)^t/14
We have to find the initial amount and the amount left after 40 hours.
For initial amount putting t = 0,
A(0) = 4300(1/2)^0
A(0) = 4300 grams.
Hence the initial amount is 4300 grams.
The amount left after 40 hours can be found by putting t = 40,
A(40) = 4300(1/2)^40/14
A(40) = 4300(0.138)
A(40) = 593.4 grams.
Hence, the amount left after 40 hours is 593.4 grams.
After 40 hours of radioactivity of uranium, 593.4 grams amount will be left while the initial un decayed amount was 4300 grams.

4x(x + 1) − (3x − 8)(x + 4)
The simplified form of the expression 4x(x + 1) − (3x − 8)(x + 4) is -3x^2 - 4x - 32.
To simplify the expression 4x(x + 1) − (3x − 8)(x + 4), we can expand the parentheses and combine like terms.
Expanding the first term, we get 4x^2 + 4x.
Expanding the second term, we have -(3x)(x) - (3x)(4) - (-8)(x) - (-8)(4), which simplifies to -3x^2 - 12x - (-8x) - (-32), further simplifying to -3x^2 - 12x + 8x - 32.
