Four hospitals are located within a city at coordinate points P1=(10,20), P2=(14,12), P3=(8,4) and P4=(32,6). The hospitals are

served by a centralized blood bank facility that is located in the city. The number of deliveries to be made each year between the blood bank facility and each hospital is estimated to be 450, 1200, 300, and 1500 respectively. If it is desired to locate the blood bank at a point that minimizes the weighted distance traveled per year, where should it be located
(i) if travel is rectilinear in the city
(ii) if travel is measured in Euclidean distance.

Answer:

The coordinates of the location of the Blood bank = ( 20.7826, 9.73913 )

Explanation:

Coordinates of the Four(4) hospitals are

P1=(10,20),   P2=(14,12),   P3=(8,4) and   P4=(32,6)

Number of deliveries to be made each year for each hospital respectively:

450,   1200,    300, and 1500

conditions :

(i) if travel is rectilinear in the city

(ii) if travel is measured in Euclidean distance.

<u>Determine where the Blood bank is to located to minimize weighted distance travelled each year </u>

find the values of the below variables :

Total load of the Hospitals( ∑load ) = 450 + 1200 + 300 + 1500 = 3450

Lx = ∑x * load = ∑ 10*450 + -------- + 32*1500 = 71700

Ly = ∑y * load = ∑ 20*450 +--------- + 6*1500 = 33600

The coordinates of the Blood bank = [ ( Lx / ( ∑load ) ) ,  Ly /  ( ∑load ) ]

                                                          =[ (71700/3450) , (33600/3450) ]

Hence The coordinates of the  location of the Blood bank = ( 20.7826, 9.73913 )

The risk-free rate of return is 4%, the required rate of return on the market is 10%, and High-Flyer stock has a beta coefficien
Bess [88]

Answer:

the share should sell at $46

Explanation:

We use the CAPM method to know the required return of the capital

Ke= r_f + \beta (r_m-r_f)

risk free 0.04

market rate 0.1

beta(non diversifiable risk) 2

Ke= 0.04 + 2 (0.06)

Ke 0.16000 = 16%

Now we calculate with the dividends grow model the intrinsic value of the share:

\frac{divends}{return-growth} = Intrinsic \: Value

\frac{4.60}{0.16-0.06} = Intrinsic \: Value

$4.6/0.1 = $46

The following information relating to a company's overhead costs is available. Actual total variable overhead $ 75,000 Actual to
NARA [144]

Answer:

$5,000 favorable

Explanation:

The computation of the total variable overhead variance is given below:

= Budgeted machine hours allowed for actual output × Budgeted variable overhead rate per machine hour - Actual total variable overhead

= 32,000 hours × $2.50 - $75,000

= $80,000 - $75,000

= $5,000 favorable

Since the favorable is more than the actual so it should be favorable

3. Suppose that all households hold all their wealth in assets that automatically rise in value when the aggregate price level r
alexira [117]

Answer:

What happens to the wealth effect of a change in the aggregate price level as a result of this allocation of assets?

  • The consumers' wealth effect will rise since the slope of the aggregate demand curve increases as the prices of assets increases, i.e. the slope of the aggregate demand curve becomes steeper as customers become wealthier.

Will aggregate demand still be downward sloping? Why or why not?

  • The aggregate demand curve sill still be downward sloping because as the price of a good or service increases, the quantity demanded will still decrease. An inverse relationship exists between price changes and quantity demanded.

Furkat [3]

Answer:

The answer is D. All of the above are plausible
