Question:

The question is incomplete.  The snapshot of a system was not added. See below the remaining part of the question and the answers.

                Allocation Max     Available            Available

                   ABCD                   ABCD                 ABCD

PO               2001                      4212                 3321

P1                  31 21                    5252

P2                2103                      2316

P3                  1312                     1424

P4                   1432                   3665

Answer:

(a) safe sequence is P0 , P3, P4, P1, P2

(b) The request can be granted

(c) The request can be granted

Explanation:

a.

Need Matrix

Need [i, j] = Max [i, j] – Allocation [i, j]

       A B C D

P0 2 2 1 1

P1 2 1 3 1

P2 0 2 1 3

P3 0 1 1 2

P4 2 2 3 3

Available = (3 3 2 1)

1. Need(P0) < Available so, P0 can take all resources

Available = (3 3 2 1) + (2 0 0 1) (Allocation of P0) = (5 3 2 2)

2. Need(P3)<Available so, P3 will go next

Available = (5 3 2 2) + (1 3 1 2) = (6 6 3 4)

Like wise next P4, P1, P2 will get resources.

So safe sequence is P0 , P3, P4, P1, P2

b.

Request from P1 is (1 1 0 0) and Available is (3 3 2 1)

As request(P1) < Available, we can grant request

c.

Request from P4 is (0 0 2 0) and Available is (3 3 2 1)

As request(P4) < Available, we can grant request

Answer:

Answer: (b) As request(P1) < Available, we can grant request

              (c) As request(P4) < Available, we can grant request

Explanation:

Need Matrix

Need [i, j] = Max [i, j] – Allocation [i, j]

              A B C D

P0        2 2 1 1

P1        2 1 3 1

P2        0 2 1 3

P3        0 1 1 2

P4        2 2 3 3

Available = (3 3 2 1)

1. Need(P0) < Available so, P0 can take all resources

Available = (3 3 2 1) + (2 0 0 1) (Allocation of P0) = (5 3 2 2)

2. Need(P3)<Available so, P3 will go next

Available = (5 3 2 2) + (1 3 1 2) = (6 6 3 4)

Like wise next P4, P1, P2 will get resources.

So safe sequence is P0 , P3, P4, P1, P2

b.

Request from P1 is (1 1 0 0) and Available is (3 3 2 1)

As request(P1) < Available, we can grant request

c.

Request from P4 is (0 0 2 0) and Available is (3 3 2 1)

As request (P4) < Available, we can grant request

Tems11 [23]

Answer: Focused differentiation strategy

Explanation: In focused differentiation strategy the focus of the entity providing the service is to make their product suitable and as per the expectations of the target market , which is very narrow in size and the requirements of the customers are very unique in such kind of target markets.

In the given case, as we know that vegetarian food is not very popular among the college students, since the preference towards health is usually seen in the age group of 25 to 35 working individuals.

Thus, the customer base of amy is very narrow.

Hence, we can conclude that Amy's is using focused differentiation strategy

Elan Coil [88]

Answer:

True. Yes, the theory can be falsified.

Explanation:

Theory X would more specifically refer to the theory of supply and demand, which states that individuals will buy more of a particular good if their income rises. From this theory, comes the concept of "normal good", which are precisely the goods that people buy more as their income rises.

This theory could be falsified by empirical observation: a study could be made, including a good number of subjects, to see whether their purchasing habits are directly related to their income.

The following provides data for an economy in a certain year. Consumption expenditures $50 Imports $40 Government purchases of g
wlad13 [49]

Answer:

$150

Explanation:

The formula to compute the GDP is as follows

GDP = Consumption + Investment + Government purchase + Net exports

where,

Consumption = Consumption of expenditure = $50

Investment = Business fixed investment + change in inventory + construction of new homes & apartments

= $30 + $10 + $30

= $70

The change in inventory is

= Ending inventory - beginning inventory

= $20 - $10

= $10

Government purchase = Government purchases of goods and services = $20

Net exports

= Exports - imports

= $50 - $40

= $10

So the value of GDP is

= $50 + $70 + $20 + $10

= $150

If patricia were to paint her living room alone, it would take 4 hours. her sister naomi could do the job in 5 hours. how long w
Mila [183]

Practicia completes the job in one hour = 1/4

Naoimi completes the job in one hour = 1/5

If Parcticia and Naoimi does it together,let us suppose in x number of hours.

The equation so form is:

(1/4)*x + (1/6)*x = 1 (i.e job finished)

The Least common multiple(LCM) of 4 and 6 = 12

12*(1/4)*x + 12*(1/6)*x = 12*1

Therefore, solving the equation we get,

3x + 2x = 12

5x = 12

x = 12/5

x= 2 2/5 hours or 2.24 hours

Therefore number of hours they took to complete the work is 2 hours and 24 minutes or 2.24 hours.
