Answer:

Explanation:

Experiments were performed for 240 people, 60 people test positive.

Step 1: we calculate the sample proportion; p= 60/240= 0.25.

Step 2: calculate the standard error for the sample, which is the square root of sample proportion,p = p(1-p)/n, n=100

0.25(1-0.25)/100

= 0.04.

Step 3: calculate the test statistics; assuming the hypothesis test percentage is 25%

Then, we say 0.25-1=0.75

-0.75/0.04

= -1.875.

In particular, the sample results are -1.875 standard error.

Probability of Z is less than -1.875.

Look up it value in the Z table

McGaha Enterprises expects earnings and dividends to grow at a rate of 28% for the next 4 years, after the growth rate in earnin
Sedbober [7]

Answer:

The current price of the common stock is $29.05

Explanation:

Cost of Equity = Rf + beta x MRP = 3% + 1.20 × 5.50% = 9.6%

Dividend in the n the year = D₀ × (1+g)^n

D₁ = $1.25 × 1.25 = $1.56255

D₂ = $1.5625 × 1.25  = $1.9531

D₃ = $1.9531 × 1.25   = $2.44

D₄ = $2.44 × 1.25 = $3.052

Terminal value = D₄ × (1+g5)/r5-g5

= $3.052 x (1+0.0) ÷ (9.60 - 0.0)

= $31.79

Total value in 4th year = $3.052 + $31.79 = $34.8409

Total cash flows = $1.5625, $1.9531, $2.4414,  $34.8409

(Present value Cash-flows at 9.60% ) $1.4256, $1.6260, $1.8544, $24.1461

= $29.05

Current price = $29.05

Lyrx [107]

Answer:

The principle of the Software Engineering Code of Ethics that Morris has violated is:

the Product principle.

Explanation:

The Product principle requires that Morris' program (product and related modifications) should meet the highest professional standards.  Staying within budget and rationalizing an error as minor are not requirements of the Software Engineering Code of Ethics that Morris subscribed to.

Other requirements of the code include acting in the best interest of the public, client, and employer; maintaining high product standards; integrity and independence in professional judgment; using an ethical approach; maintaining professional integrity and independence; being fair and supportive to colleagues; and ensuring participation in lifelong learning.

Jones borrowed $960 from the bank, issuing a 12.5%, 4-month promissory note. Assuming that the note is issued and paid in the sa
Anestetic [448]

Answer:

(A). A Debit to Notes Payable for $960

Explanation:

In case of a promissory note, there are three parties to it, namely,

  1. Maker i.e Jones here
  2. Payee, to whom money is to be paid i.e the bank here
  3. Holder i.e the one who currently holds the promissory note i.e the bank here

Upon issue of promissory note, in the books of the maker (Jones), the entry is,

Name Of The Bank A/C                    Dr. $960

      To Notes Payable A/C                              960

(Being a promissory note issued to bank against a payment of $960)

Upon maturity i.e date of payment, the entry would be,

Notes Payable A/C                           Dr.  $960

     To Cash/Bank A/C                                      960

(Being payment of promissory note honored)

Thus, the correct answer would be, (A) a debit to notes payable account for $960.

Stocks that don't pay dividends yet
mariarad [96]

Answer:

horizon value at year 5 = $94.3444

current intrinsic intrinsic value P₀ = $47.73

Assuming that the markets are in equilibrium, Goodwin's current expected dividend yield is and Goodwin's capital gains yield is <u>0(it pays no dividends)</u>.

Goodwin has been very successful, but it hasn't paid a dividend yet. It circulates a report to its key investors containing the following statement:

Goodwin's investment opportunities are poor.

Is this statement a possible explanation for why the firm hasn't paid a dividend yet?

<u>B. False</u>

Generally companies that are experiencing a rapid growth do not pay dividends, because they need all the cash that they can use to finance their expansion. Sometimes mature companies that have a steady growth rate will also choose not to pay dividends because they consider themselves as solid investments and not paying dividends allows them to grow more and should increase stockholders' wealth more.

Explanation:

D₃ = $5.50

D₄ = $7.073

D₅ = $9.096

D₆ = $9.642 (and a constant growth rate of 4.38%

Re = 14.60%

horizon value at year 5 = $9.642 / (14.6% - 4.38%) = $94.3444

intrinsic value P₀ = $94.3444 / 1.146⁵ = $47.73
