Answer:

-28.1%

Explanation:

Calculation for what would a​ 30% loss next year be outside the​ 95% confidence interval for the​ portfolio

The standard deviation of 95% confident will be 2

The first step is to find the Upper tail using this formula

Upper tail= Average return percentage +(Standard deviation of 95% confident *Standard deviation of its returns)

Let plug in the formula

Upper tail=0.113+(2*0.197)

Upper tail =0.113+0.394

Upper tail=0.507*100

Upper tail =50.7%

Second step is to find the Lower tail using this formula

Lower tail=Average return percentage -(Standard deviation of 95% confident *Standard deviation of its returns)

Let plug in the formula

Upper tail=0.113-(2*0.197)

Upper tail =0.113-0.394

Upper tail=-0.281*100

Upper tail =28.1%

Based on the above calculation the lower tail was -28.1% which means that it wouldn't in any way loss more than the 30% of it value next year outside the​ 95% confidence interval for the portfolio

kicyunya [14]

Matthew decides to buy expensive designer jeans. Less expensive jeans are available, but the added cost of the designer brand is worth it to Matthew most likely because His preference is for designer labels, since the assertions made by the other manufacturers, which claim that designer trousers are less expensive, are illogical. This is further explained below.

<h3>What is the cost?</h3>

Generally, payment is required before it can be obtained or completed.

In conclusion, Affluent designer jeans are Matthew's choice. There are cheaper jeans out there, but Matthew most certainly prefers designer labels since the arguments of the other manufacturers, who say that designer pants are less costly, are irrational.

Anna [14]

Answer:

$2.25

Explanation:

sale volume of company = 30,000 unit

total fixed cost are = $30,000

total variable cost $45,000 for 30,000 unit

1 unit = 45000/30000 =  $ 1 . 5

for the sale of 40,000 unit

the  total expected cost

    = Fixed cost + Variable cost

      = $30,000 + 40,000×$1.50

      = $30,000+$60,000

     = $90,000

Cost per unit:

 = $90,000/40,000

=  $2.25
