A history is an interview of the patient that includes the following elements:

An investment earned the following returns over a four-year period: 28 percent, 21 percent, 1 percent, and -36 percent. What is

riadik2000 [5.3K]

Answer:

A) 0.0618

Explanation:

Variance is given by:

$V = \frac{\sum(Xi - \mu)^2}{n}$

Where 'Xi' is the value for each term 'i' in the sample of size 'n' and μ is the sample mean.

The mean investment return is:

$\mu = \frac{0.28+0.21+0.01-0.36}{4} \\\mu = 0.035$

The variance is:

$V = \frac{\sum(Xi - \mu)^2}{n}\\V = \frac{(0.28- 0.035)^2+(0.21- 0.035)^2+(0.01- 0.035)^2+(-0.36- 0.035)^2}{4}\\V= 0.0618$

The variance of the returns on this investment is A) 0.0618.

Today, you turn 21. Your birthday wish is that you will be a millionaire by your 40th birthday. In an attempt to reach this goal

Degger [83]

Answer:

rate of 0.000171716533316905 = 0.017% daily

Explanation:

we need to solve for the rate of an annuity for 19 years with daily deposits of 75 dolllars to yield a principal of 1,000,000 dollars

365 days x 19 years = 6,935 days

we use goal seek on excel as follow:

on A1 we write 0.01 this will be a placeholder for the rate

then on A2 we write =FV(A1;6935;75)

then with goal seek we definethat we want A2 equal to 1,000,000 changing A1 (rate)

which give us:

0.000171717 = 0.017% per day to achieve the goal:

$C \times \frac{(1+r)^{time} -1}{rate} = FV\\$

C 75

time 6935

rate 0.000171717

$75 \times \frac{1-(1+0.000171716533316905)^{-6935} }{0.000171716533316905} = FV\\$

FV $999,999.9999

Henrietta, the owner of a very successful hotel chain in the Southeast, is exploring the possibility of expanding the chain into

Sholpan [36]

Answer:

a. The amount Henrietta can deduct in the current year for investigating the possibility of expanding the hotel chain a city in the Northeast is $67,000.

b. Amount she can deduct in the current year is $2,088.88.

Explanation:

a. Determine the amount Henrietta can deduct in the current year for investigating the possibility of expanding the hotel chain.

Since the primary business of Henrietta is the hotel business, all the expenses she incurred in investigating the possibility of expanding the chain into another city is deductible in the current year despite that she decides not to expand.

Therefore, the amount Henrietta can deduct in the current year for investigating the possibility of expanding the hotel chain a city in the Northeast is $67,000.

b. Determine the amount Henrietta can deduct in the current year for investigating opening a restaurant.

Since the primary business of Henrietta is not a restaurant business, the amount she can deduct in the current year can b determined as follows:

Of the$51,000, an amount of $4,000 [$5,000 − $1,000 (reduction for excess over $50,000)] can be immediately expensed.

The balance of $47,000 ($51,000 − $4,000) is amortized over a period of 180 months at the rate of $261.11 per month ($47,000 ÷ 180) starting from May. Therefore, we have:

Amount she can deduct in the current year = Amount deductible per month * Number of months between May 1 to December 31 = $261.11 * 8 = $2,088.88

If the total revenue variance is favorable and the revenue price variance is unfavorable, then the revenue volume variance must

Ostrovityanka [42]

Answer: a.exceed the revenue price variance and be favorable

Explanation:

Revenue Volume x Revenue Price = Total Revenue

From the above formula, for the Total Revenue to be variated positively and yet the Revenue Price is of Negative Variance, it would follow logically that the other variable in the transaction contributed to the favorable variance of the Total Revenue apart from the Revenue Price.

The only other variable is the Revenue Volume. The Revenue volume must therefore have been large and favorable enough to offset the Negative Variance of the Revenue Price.
