Answer:

the standard deviation for the sample is 6.83%

Explanation:

∑ ( (x1-X)^2 ) / N-1

whre X is the mean of the sample and N is the number of samples.

Year Return

2010  21.00%

2009 12.50%

2008 25.00%

Average: (0.21 + 0.125 + 0.25 )/3 = 0.195

Difference between average and actual result squared:

(0.21-0.195)^2+(0.125 -0.195)^2+(0.25 -195)^2 =

(0.015)^2+(-0.07)^2+(0.055)^2 = 0.00815

1/(N-1) = 1/(3-1) = 1/2

standard deviation = √(0.00815/2) = 0.06837397166 = 6.83%

Lelechka [254]

Answer:

Compound interest; amortized loans; amortization schedule; largest; decline; smallest; increases.

Explanation:

An important application of compound interest involves amortized loans. Some common types of amortized loans are automobile loans, home mortgage loans, and business loans. Each loan payment consists of interest and repayment of principal. This breakdown is often developed in an amortization schedule. Interest is largest in the first period and declines over the life of the loan, while the principal repayment is smallest in the first period and it increases thereafter.

Amortization in accounting is used to periodically lower the book value of a loan principal or an intangible asset such as intellectual property over a set period of time.

The compound interest formula is given below;

A = P(1 + \frac{r}{n})^{nt}

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

CDF Appliances has assembly plants in Atlanta and Fort Worth where it produces a variety of kitchen appliances, including a 12-c
zloy xaker [14]

Answer:

Cappuccino machines should be produced in Atlanta and coffee makers in Fort Worth. The Fort Worth facility would need to operate 100 hours per week and the Atlanta facility would need to operate 140 hours per week.

Total costs associated to operating the facilities = ($2,400 x 100) + ($600 x 140) = $324,000

Explanation:

Since there is not constraint regarding the total number of labor hours that each plant can operate, then we must choose the plant that operates at the lower cost. The only restriction is total time = 7 days x 24 hours = 168 hours per week:

production costs Atlanta:

coffee maker = $600 / 160 = $3.75 per unit

cappuccino machine = $600 / 200 = $3 per unit

production costs Fort Worth:

coffee maker = $2,400 / 800 = $3 per unit

cappuccino machine = $2,400 / 200 = $6 per unit

Cappuccino machines should be produced in Atlanta and coffee makers in Fort Worth. The Fort Worth facility would need to operate 100 hours per week and the Atlanta facility would need to operate 140 hours per week.

Annie is self-employed and has $58,000 in income from her business. She also has investments that generated dividends of $3,000
8090 [49]
First, you need to know the self-employment taxes:
The self-employment tax is 92.35%
Social security tax is 12.4% and Medicare tax is 2.9% = (15.3%)

Dividends and interest are not a part of the income.

58000 * 92.35% *15.3% 
Turn the percentages into decimal form in order to multiply. You can do this by moving the decimals over twice or dividing each percentage by 100. 

58000*.9235 * .153 = $8,195.

Annie's self-employment tax for the year is $8,195.
