The statement that One disadvantage of the DBMS is that it increases the risk of data security breaches is false. In contradiction the DBMS decreases the security risk.

I think this statement is false because instead DBMS actually decreases the security risk of data security breaches. DBMS is a system software for creating and managing data. It is the only way of accessing the data in a database and does not reveal much of the databases internal complexity to the application programs and users.

Two investment advisers are comparing performance. One averaged a 19% return and the other a 16% return. However, the beta for t

finlep [7]

Answer: Adviser B is the superior stock selector.

Explanation:

For the comparision between the two investment advisers, the Jenson's Alpha will be utilized.

Jenson's Alpha:

= Portfolio Actual Return - CAPM(Benchmark Portfolio Return)

T Bill Rate(Risk free rate) = 6%

Market return(E(Em) = 14%

Beta of Investment Adviser A = 1.5

Beta of Investment Adviser B = 1

For Adviser A:

CAPM = Risk free return + Beta ( E(Rm) - Risk free return)

CAPM(Benchmark Portfolio) = 6 + 1.5 (14-6)

= 6 + 12

= 18%

Actual Return = 19%

Jenson's Alpha = 19% - 18% = 1%

For Adviser B:

CAPM = Risk free return + Beta ( E(Rm) - Risk free return)

CAPM(Benchmark Portfolio) = 6 + 1(14-6) = 6 + 1(8) = 14%

Actual Return = 16%

Jenson's Alpha = 16% - 14% = 2%

Adviser B is a better selector because he has a larger alpha of 2% compared to Adviser A who has 1%.

T Bill Rate(Risk free rate) = 3%

Market return(E(Rm) = 15%

Beta of Investment Adviser A = 1.5

Beta of Investment Adviser B = 1

For Adviser A:

CAPM = Risk free return + Beta ( E(Rm) - Risk free return)

CAPM(Benchmark Portfolio) = 3 + 1.5 (15-3)

= 3 + 18

= 21%

Actual Return = 19%

Jenson's Alpha = 19% - 21% = -2%

For Adviser B:

CAPM = Risk free return + Beta ( E(Rm) - Risk free return)

CAPM(Benchmark Portfolio) = 3 + 1(15-3) = 3 + 1(12) = 15%

Actual Return = 16%

Jenson's Alpha = 16% - 15% = 1%

Given the changes, Adviser B is still the better selector because he has a larger alpha of 1% compared to Adviser A who has -2%.

Mission Foods produces two flavors of tacos, chicken, and fish, with the following characteristics:

postnew [5]

Answer:

1. $858,000

2. Chicken = 24,000 units and Fish = 36,000 units

Explanation:

The computation is shown below:

1. The anticipated level of profits for the expected sales volumes is

= Expected sales of chicken × (Selling price per taco - Variable cost per taco) + Expected sales of fish × (Selling price per taco - Variable cost per taco) - total fixed cost

= 200,000 × ($3 - $1.50) + 300,000 × ($4.50 - $2.25) - $117,000

= $300,000 + $675,000 - $117,000

= $858,000

2. The break even volume is

Let we assume the sale units be X

So, total units sold for chicken = 40X

And, for the fish it is = 60X

Sale units of chicken × (Selling price per taco - Variable cost per taco) + Sale units of chicken × (Selling price per taco - Variable cost per taco) = Total Fixed cost

0.40X × (3 – 1.50) + 0.60X × (4.50 – 2.25) = $117,000

0.60X + 1.35X = $117,000

1.95X = $117,000

So, the X is 60,000 units

So for chicken it is 60,000 × 40% = 24,000 units

And for fish it is 60,000 × 60% = 36,000 units

Storico Co. just paid a dividend of $2.05 per share. The company will increase its dividend by 24 percent next year and then red

VikaD [51]

Answer:

A share of stock sell for $74.21 today.

Explanation:

This can be calculated as follows:

Dividend per share in year 1 = Year 0 dividend * (1 + growth rate of year 1 dividend) = $2.05 * (1 + 24%) = $2.5420

PV of year 1 dividend per share = Year 1 dividend / (1 + rate of return)^1 = $2.5420 * / (1 + 10%)^1 = $2.31090909090909

Dividend per share in year 2 = Year 1 dividend * (1 + growth rate of year 1 dividend) = $2.5420 * (1 + (24% -6%)) = $2.5420 * (1 + 18%) =$3.00

PV of year 2 dividend per share = Year 2 dividend / (1 + rate of return)^2 = $3.00 / (1 + 10%)^2 = $2.47933884297521

Dividend per share in year 3 = Year 2 dividend * (1 + growth rate of year 2 dividend) = $3.00 * (1 + (18% -6%)) = $3.00 * (1 + 12%) =$3.36

PV of year 3 dividend per share = Year 3 dividend / (1 + rate of return)^3 = $3.36 / (1 + 10%)^3 = $2.5244177310293

Dividend per share in year 4 = Year 3 dividend * (1 + growth rate of year 3 dividend) = $3.36 * (1 + (12% -6%)) = $3.36 * (1 + 6%) =$3.5616

PV of year 4 dividend per share = Year 4 dividend / (1 + rate of return)^4 = $3.5616 / (1 + 10%)^4 = $2.43262072262824

Dividend per share in year 5 = Year 4 dividend * (1 + growth rate of year 4 dividend) = $3.5616 * (1 + 6%) = $3.775296

Price at year 4 = Year 5 dividend / (Rate of return – growth rate) = $3.775296 / (10% - 6%) = $94.3824

PV of price at year 4 = Price at year 4 / (1 + rate of return)^4 = $94.3824 / (1 + 10%)^4 = $64.4644491496482

Share price to day = PV of year 1 dividend per share + PV of year 2 dividend per share + PV of year 4 dividend per share + PV of year 4 dividend per share + PV of price at year 4 = $2.31090909090909 + $2.47933884297521 + $2.5244177310293 + $2.43262072262824 + $64.4644491496482 = $74.21
