Answer:

Total bet amount= -$2

Explanation:

In a card deck of 52 cards we have 13 diamond cards. Cards are drawn without replacement.

Probability of the first card being diamond = 13/52

Probability of the send card being diamond= 12/51

So the probability for both cards being diamond = (13/52)*(12/51)= 0.0588235

Bet amount for 2 diamonds= probability* amount received

Bet amount for 2 diamonds= 0.0588235* $30= $1.765

Probability of no diamond= 1- 0.0588235

Probability of no diamond= 0.94118

Bet amount for no diamonds= 0.94118* (-$4)

Bet amount for no diamonds= -$3.765

Total bet amount= Bet amount for diamonds + bet amount for no diamonds

Total bet amount= $1.765+ (-$3.765)

Total bet amount= -$2

gizmo_the_mogwai [7]

Answer: 45%

Explanation:

Standard deviation for the portfolio will be a weighted average of the standard deviations of the individual assets.

Risky asset has standard deviation of 20%. Assume the weight is x.

Treasury bills have a standard deviation of 0 as they have no risk. Assume their weight is y.

Target Standard deviation is 9%.

Formula would be:

9% = (x * 20%) + (y * 0%)

20%x = 9%

x = 9% / 20%

x = 45%

Colt1911 [192]

Answer:

The maximum mortgage payment (PITI) a lender would allow for a conventional loan based on the housing expense ratio is:

$1,506.40

Explanation:

a) Data and Calculations:

Lisa works 40 hours at $18 an hour

Lisa weekly income = 40 * $18 = $720

Lisa monthly income = 40 *$18 * 4 = $2,880

Dave weekly income = $625

Dave's monthly income = $625 * 4 = 2,500

Total joint monthly income =            $5,380

b) If Lisa and Dave, her husband, file jointly for taxes, then the maximum mortgage payment (PITI) they can make is 28% of the gross income.

Therefore PITI = $5,380 * 28% = $1,506.40

c) The housing expense ratio is the percentage of your gross monthly income devoted to housing expenses, which should not exceed 36% of your monthly or annual gross income.  According to the general rule, the household expense payments, primarily rent or mortgage payments, cannot exceed more than 28% of the monthly or annual income.

Perth Mining Company operates two mines for the purpose of extracting gold and silver. The Saddle Mine costs $12,000/day to oper
stepan [7]

Answer:

Operate mine 1 four 4 days and mine 2 during 6 days to obtain minimum cost for the desired output of 850 gold and 18,000 silver

Explanation:

We generate the equation system on excel:

(50g + 3000s) Q_1 --> output generated on Mine 1

(75g + 1,000s) Q_2 --> output generated on Mine 2

12,000 Q1 + 17,000 Q2 = cost of the mines

we do solver to minimize the days of each mine considering a desired output of 18,000 silver and 650 gold:

and get the following:

M1  4 days  output: (50g + 3000s) 4 = 200 g    12,000s

M2 6 days  output: (75g + 1,000s) 6 =  450g      6,000s

Cost: 12,000 x 4 + 17,000 x 6 = 150,000
