Answer:

2.361

Explanation:

Calculation to Find the value of the test statistic

Based on the given information let our:

p=0.25

x = 159

n = 540

Since our p is 0.25 the first step is to find q using this formula

q = 1 - p

Let plug in the formula

q = 1-0.25

q= 0.75

Second step is to find the psample using this formula

psample= x/n

Let plug in the formula

psample= 159/540

psample = 0.294

Last step is to find the value of the test statistic

Using this formula

z= (psample - p) / √(pq/n)

Let plug in the formula

z = (0.294 - 0.25) / √(0.25×0.75/540)

z=0.044/√(0.1875/540)

z=0.044/√(0.000347222222)

z=0.044/0.01863389

z=2.361

Therefore the value of the test statistic will be 2.361

Consider an offer to supply 5 paintings per year to an art gallery in Rome for the next five years. The contract is exclusive, m
IceJOKER [234]

Answer:

I will accept the offer if the price per painting is $56,312.41 or higher.

Explanation:

We will calculate the present value of the other option which is, selling our painting as a freelancer.

C \times \frac{1-(1+r)^{-time} }{rate} = PV\\

C 315,000.00

time 5

rate 0.2

315000 \times \frac{1-(1+0.2)^{-5} }{0.2} = PV\\

PV $942,042.8241

Now, we subtract the signing bonus of 100,000

942,042.83 - 100,000 = 842,042.83

And solve for the annual proceeds from the painting we need to equalize the opportunity cost:

PV \div \frac{1-(1+r)^{-time} }{rate} = C\\

PV 842,042.83

time 5

rate 0.2

842042.83 \div \frac{1-(1+0.2)^{-5} }{0.2} = C\\

C  $ 281,562.03

Now, we divide by the 5 painting per year:

$281,562.03 per year / 5 painting per year = $56,312.41

Whitepunk [10]

Answer with Explanation:

Tangible assets fall under the scope of International Accounting Standard IAS-36 Property, Plant and Equipment which says that assets that qualify following conditions, must be capitalized:

  • Assets that have life expectancy of more than a year.
  • Benefits of the Assets are controlled by the entity that will flow towards the company.

Now here, the life expectancy of laboratory equipment is unknown and also that we don't know if the asset can be resold in the market or not. This means, if the asset has life expectancy is no more than a year and that the future benefits will flow towards the company then it must be capitalized otherwise it must be expensed out as per the guidelines of International Accounting Standard IAS-38 Intangible Assets, which says that the research cost prior to the development expenditure must be expensed out.

The other two costs are revenue expenditure and must be expensed out under the name research and development cost as per the guidelines of IAS-38.

Real per capita GDP in Singapore in 1960 was about $450, but it doubled to about $900.00 by 1977. a. What was the average annual
aleksandrvk [35]

Answer:

4.16%

Explanation:

to calculate Singapore's economic growth rate we can use the future value formula (we could also use the rule of 72 but it is not very exact):

future value = present value x (1 + r) ⁿ

  • future value = 900
  • present value = 450
  • n = 17
  • r = ?

900 = 450 (1 + r)¹⁷

(1 + r)¹⁷ = 900 / 450 = 2

1 + r = ¹⁷√2 = 1.0416

r = 1.0416 - 1 = 0.0416 or 4.16%
