Answer:
c. 65 and 85 months
Explanation:
Life tests performed on a sample of 100 batteries indicated:
(1) an average life of 75 months,
(2) a standard deviation of 5 months, and
(3) battery life is approximately normally distributed.
We create a 95% CI around mean.
If 95% is in the middle, then 5% is in the ends, 2.5% in each end.
Z score at .025 is -1.96, z score at .975 is +1.96
To convert z to battery life:
Z*sd + mean = battery life
-1.96*5 + 75 = 65.2, rounds to 65
+1.96*5 + 75 = 84.8, rounds to 85
Answer:
loanable amount after Fed operation = $950 M
Securities after fed operation = $50 M
attached below is the T-account table
Explanation:
Given data:
For assets : securities = $100 M , Loans = $800 M
For Liabilities : Constant demand deposit = $1000 M
difference between the assets and liability = $100 M and this makes the Banking system unbalanced hence the Banking system needs the intervention of the Fed. and the reduction in the required reserve ratio from 10% to 5% is the right action
How with the reserve ratio reduced to: 0.05
hence required Minimum required securities after operation = 0.05 * 1000 M = 50 M
Note : Total demand deposits = securities + loanable amount
therefore loanable amount after Fed operation = $1000 M - $50 M = $950
Attached below is the T-table
When both tables are compared it can be seen that there is a significant increase in the loanable amount after the Fed's operations and increase in Loanable amount transcends to increase in Monetary base
Answer:
The correct answer is B.
Explanation:
I had to look at the options so that I could solve the exercise correctly. The options are:
A) The forced vital capacity (FVC) is high.
B) The forced expiratory volume (FEV) is decreased.
C) Total lung capacity (TLC) is decreased.
D) Marked decrease in residual volume (RV).
The correct answer is option B. In people with chronic lung disease, FVC is decreased, FEV1.0 is decreased, and the ratio of FEV1.0 to FVC is decreased. Lung volume measurements indicate a large increase in VR, an increase in total lung Cc, and an elevation in the ratio of VR to TVC.
Have a nice day!
Answer:
Explanation:
Last year Current year
Selling Price 10 10
Varaible Price 5 6
Contribution Margin 5 4
Break even is the point where total cost is equal to total revenue mean no profit and loss.
company earns the contribution margin after covering the variable cost, now only fix cost remains for break even.
Break Even using FIFO method : first In first out system
Fix Cost = 86000
contribution from opening units(6000*5) = 30000
Remaining Fix cost that should be Covered from
current year products = 56000
Units to be sold for break-even ( 56000/4) = 14000
so we have break even units 6000+14000 = 20000
Fix cost = -86000
Opening 6000*5 = 30000
Current 14000*4 = 56000
Profit = 0
Break Even using LIFO method : Last in first out
Fix Cost = 86000
Break even = Fix Cost / Contribution margin
Break even = 86000/4 =21500
current production is 24000 which is higher than break even units so we can cover the fix cost from current year production because company is using lifo method. we do not need opening units for the break even.
