I guess the correct answer is An increase in the costs of exploration and drilling for oil
A leftward shift of the supply curve for oil in the United States is most likely to result from an increase in the costs of exploration and drilling for oil.
Answer:
0.9
Explanation:
The formula to compute the four-firm concentration ratio is shown below:
= (Total firm sales of industry A) ÷ (Total firm sales of industry B)
where,
Total firm sales of industry A = $5 million + $2 million + $1 million + $1 million
= $9 million
And, the total firm sales of industry B would be
= $2.5 million × 4 firms
= $10 million
So, the ratio would be
= $9 million ÷ $10 million
= 0.9
This one is tricky, only because you aren't sure if they are adding the percentage before you deposit 4,000 more, or after. Since both are annually.
But I would add 11,122.76 and 4,000 =15,122.76 add 12% which is 1814.73 making your total for the first year = 16,937.49.
Then assume it again, you add 4,000. That's 20,937.49
add 12% of 20,937.49 which is 2512.50 so that equals =23,449.99 by the end of year 2.
so add 4,000 again, that's 27,449.99
find 12% and add it to get =3294 add that to the total =30,743.99 by year 3.
(I'm sure they want you to round, which I keep doing with my decimals, but it'll probably go faster if you round ahead of time, but I'm trying to be accurate)
Keep going....
34,743.99 which 12% added is 4169 or a total of $38,912.99 by end of year 4.
add 4,000 to get =42,912.99 and 12% that's roughly a total of 48,063 rounded by the end of year 5.
52,063 at 12% 58,310 by year 6.
58,000 add 12% = 64,960 at end of year 7
68,960 add 12%= 77235 at year 8
81,235 add 12% =90,983 by year 9
94,983 add 12% =106,380 by year 10 (this is where you can assume that they'd want you to double it and it's be 20 years and 210,000. But in real math, the amount is increasing so much because it's 12% of the current balance)
123,626.56 year 11
142,942 by year 12
164,574 by year 13
188,803 by year 14
203, 939 by year 15
So you'd go over 210 by year 16.
Now again, this depends if they add the 12% before or after you deposit 4,000 each year. It also has to have an easier equation, but to be accurate I did it this way. I'm sure that they want you to do like x=years and you'd go 11,122.76+4,000 multiplied by 12% and then try different years to see the number you get until you'd come to 16.
Answer: D. The auditor is likely to increase control risk because the computed upper deviation rate is greater than the tolerable deviation rate
Explanation: For this scenario, the only true option is that, the auditor is likely to increase control risk because the computed upper deviation rate is greater than the tolerable deviation rate.
Attributed sampling states that items being sampled will either or won't possess certain attributes or quantities.
