Answers and explanations:

1) A modification problem takes places when creating a database two different type of information is entered in the same chart row generating inaccuracy. The only form to solve this issue is creating a new row so each piece of information will be stored in one row particularly.

2) There are three (3) types of modification problems: the deletion problem (the single row containing information from different themes can be deleted losing data), the update problem (new information entered could lead to more inconsistency), and the insertion problem (similar to deletion, a new row can be inserted instead of the row causing problem but information will be missing).

KIM [24]

Answer;

Explanation:

two types of industries are made mention of in this question.

1)Local Fledgling Industries

2)Export Dependent Industries,who are being forced to buy products from local industries now.

Since the Government has placed a ban on the importation of the products that are being made by the local fledgling industries. The implication of this is that:

1. Buyers of those import products will experience a rise in the Cost of those products as the competition faced by the Fledging industries decreases.

2. Competing becomes difficult for Export dependent industries. This is because of inflation. They now have to buy the same product at an inflated cost, thereby reducing profits.

liubo4ka [24]

Answer:

See below

Explanation:

The above is an incomplete question. The concluding parts are assuming the following;

Selling price per unit = $54

Current total variable cost = $24.50

Total fixed cost = $69,000

New variable cost will increase by ($2.26 - $1.76)/2 = $0.25

New variable cost will be = ($24.50 + $0.25) = $24.75

Contribution margin = ($54 - $24.75) = $29.25

New fixed cost = ($0.25 × 2,339) + $69,000 = $69,585

Note:

Old break even units = $69,000/$29.5 = 2,335 units

Therefore,

New break even units

= Fixed cost/Contribution margin per unit

= $69,585/$29.5

= 2,397 units

Cozy would have to sell 2,397 units as opposed to 2,335 units in order to break even.

An investor is considering two investment, an office building and bonds. He can only invest on of them. The possible return from

Hitman42 [59]

Answer:

1) Calculate the expected return and variance of investing in office building.

expected return:

$50,000 x 0.3 = $15,000

$60,000 x 0.2 = $12,000

$80,000 x 0.1 = $8,000

$10,000 x 0.3 = $3,000

$0 x 0.1 = $0

expected return = $38,000

$50,000 - $38,000 = -$12,000² = $144,000,000

$60,000 - $38,000 = -$22,000² = $484,000,000

$80,000 - $38,000 = -$42,000² = $1,764,000,000

$10,000 - $38,000 = -$28,000² = $784,000,000

$0 - $38,000 = -$38,000² = $1,444,000,000

expected variance: (0.3 x $144,000,000) + (0.2 x $484,000,000) + (0.1 x $1,764,000,000) + (0.3 x $784,000,000) + (0.1 x $1,444,000,000) = $43,200,000 + $96,200,000 + $176,400,000 + $235,200,000 + $144,400,000 = $695,400,000

standard deviation = √$895,800,000 = $26,370

2) Calculate the expected return and variance of investing in bonds.

expected return:

$30,000 x 0.4 = $12,000

$40,000 x 0.6 = $24,000

expected return = $36,000

$30,000 - $36,000 = -$6,000² = $36,000,000

$40,000 - $36,000 = $4,000² = $16,000,000

expected variance: (0.4 x $36,000,000) + (0.6 x $16,000,000) = $14,400,000 + $9,600,000 = $24,000,000

standard deviation = √$24,000,000 = $4,899

3) Based on the expected return we should choose investing in a building, but if we consider the variance and the standard deviation of the investments, I would choose investing in bonds. The difference in expected returns is not that large (only $2,000) but the variance and standard deviations of investing in the office buildings is quite large, meaning that the risk is very high.
