This is binomial distribution problem. <span>
We are given that:</span>

n = sample size = 500

p = proportion which burns wood = 0.27,

q = proportion which does not burn wood = 1-p = 0.73 

<span>
A. Mean is calculated as:</span>

Mean = n*p

Mean = 500 * 0.27

Mean = 135 

<span>
B. Variance is calculated as:</span>

Variance = n*p*q

Variance = 500*0.27*0.73

Variance = 98.55 

<span>
C. Standard deviation is calculated as:</span>

Standard deviation = sqrt(variance)

Standard deviation = sqrt(98.55)

<span>Standard deviation = 9.93</span>

Suppose the typical Buffalo Bills fan has the following demand curve for Bills football games: P = 120 – 10G where G is the numb
Vika [28.1K]

Answer:

(a) If the Bills want to sell tickets to all 8 games by selling eight individual tickets, they have to set the price P = 120 − 10(8) = 120 − 80 = $40. This yields revenue of $40(8) = $320 from each fan.

(b) If the Bills practice second degree price discrimination, they can effectively charge

P = 120 − 10(1) = 120 − 10 = $110 for single games,

P = 110 + 100 + 90 + 80 = $380 = $95/ticket for a 4-game package, and

P = 110 + 100 + 90 + 80 + 70 + 60 + 50 +40 = $600 = $75/ticket for an 8-game package.

Determine the annual financing cost of a 6-month (182-day) 20,000 discounted bank loan at a stated annual interest rate of 10 pe
ratelena [41]

Answer:

10.52%

Explanation:

The computation of the annual financing cost is shown below:

First we have to calculate the interest cost that is shown below:

= $20,000 × 10% × 182 days ÷ 365 days

= $997.26

Now the used funds is

= $20,000 - $997.26

= $19,003

Now the annual financing cost is

= ($997 ÷ $19,003) × (365 days ÷ 182 days)

= 10.52%

We assume there are 365 days in a year

"jasper company, inc. Is a wholesaler that buys merchandise in large quantities. Its supplier's catalog indicates a list price o
Setler [38]

Answer: Jasper's net purchase price unit is $357.

Since Jasper orders in large quantities, Japser is eligible for the trader's discount at 30%.

So, the price per unit will be:

Price per unit after discount = 500 * (1 - 0.3) = 350

Shipping costs are charged by the shipper and Jasper doesn't get any discounts from the shipper. So, we add shipping costs per unit to the discounted price per unit to arrive at the purchase price per unit.

Purchase Price = Discounted Price + Shipping Costs

Purchase Price = 350 + 7 = 357
