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
Answer:
Limited liability company
Explanation:
In simple words, A limited liability corporation (LLC) is a type of private company structure. It's among the most frequent legal structures for forming a company. In a comprehensive partnerships all members are accountable for the firm and have unlimited accountability for its obligations.
Thus the limited liability structure is most suitable for the two.
Answer:
income summary 550 debit
retained earnings 550 credit
--to close income sumary against RE--
Explanation:
To complete the closing entries we should determinate the balance of the Income Summary account and then, transfer into Retained Earnings.
Income Summary
<u> Debit Credit </u>
2,450
<u> 3,000 </u>
Balance 550
We will debit income summary so his blanace ends in zero and credit retained earnings so net income is accumualted and added into equity to represent it in the balance sheet.
<span>The total equivalent warming impact (TEWI) takes into consideration both the direct and indirect global warming effects of refrigerants.
In addition to the direct impact of the refrigerant (which is conveniently estimated by GWP), any system or process, which requires energy input, indirectly affects the environment. This impact is originated from CO2 emissions from the energy production processes.
TEWI can be calculated using the equation below:
TEWI = direct emissions + indirect emissions = (GWP×L×N)+(Ea×β×n),
where
L – annual leakage rate in the system, kg (3% of refrigerant charge annually),
N – life of the system, years (15 years),
n – system running time, years (based on weather data, 4910 hours),
Ea – energy consumption, kWh per year (modelled for each refrigerant),
β – carbon dioxide emission factor, CO2-eq. emissions per kWh (165 g CO2/kWh).</span>
