Answer: The manager should include 7 independent variables in her multiple regression analysis .

Explanation:

Given : The manager wants to forecast annual sales revenues of snekers of different categories.

The given categories are :-

Sports , color , gender.

Also when we have a categorical variable that assumes n different divisions then the number of dummy explanatory variable for multiple regression will be n-1.

Number of types of sports = 3

⇒ Number of dummy variables for types of sports = 3-1 =2

Number of types of color = 5

⇒ Number of dummy variables for types of color = 5-1 =4

Number of types of gender = 2

⇒ Number of dummy variables for gender = 2-1 =1

Now, the total number of independent variables = 4+2+1=7

Hence, the manager should include 7 independent variables in her multiple regression analysis .

victus00 [196]

Answer:

The investor will pay up the rereofitted pumps in a period of 22.52 months.

Explanation:

<em><u>First,</u></em> we solve for the amount of profit generate per month:

21,000 gallons a month x $0.09 per gallon = $1,890

Now, we calcualte the time at which an monthly income of 1890 discounted at 2% per month matches a present value of 34,000

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

C  $1,890.00

time    n

rate 0.02

PV $34,000.0000

1890 \times \frac{1-(1+0.02)^{-n} }{0.02} = 34000\\

(1+0.02)^{-n}= 1-\frac{34000\times0.02}{1890}

(1+0.02)^{-n}=  0.64021164

We use logarithmics properties to solve for n:

-n= \frac{log0.64021164021164}{log(1+0.02)

-22.52006579

n = 22.5200 = 22 and a half month.

son4ous [18]

Answer:

5.98  years

Explanation:

The computation of the payback period is shown below:

In year 0 = -$1,530,000

In year 1 = $305,000

In year 2 = $270,000

In year 3 = $240,000

In year 4 = $240,000

In year 5 = $240,000

In year 6 = $240,000

In year 7 = $240,000

In year 8 = $240,000

In year 9 = $240,000

In year 10 = $240,000

If we added the first 5 year cash inflows than it would be $1,295,000

Now we have to subtract the $1,295,000 from the $1,530,000 , so the amount would be $235,000 as if we sum the six year cash inflow so the total amount is exceeded to the initial investment. So, we subtract it

And, the next year cash inflow is $240,000

So, the payback period equal to

= 5 years + $235,000 ÷ $240,000

= 5.98  years

Alex777 [14]

Answer:

$47,605.83

Explanation:

future value of Takashi's savings = $30,000 x 7.3359 (FVIFA, 8%, 6 periods) = $220,077

the value of each distribution payment = $220,077 / 4.6229 (PVIFA, 8%, 6 periods) = $47,605.83

These are ordinary annuities, therefore, so we can find their annuity factors using a table.
