Answer:

Explanation:

Number of bulbs = 20

Success of a bulb lightning properly = 0.92

Success of a bulb not lightning properly = 0.08

We have to find the probability of atmost 3 bulbs not lightning properly -

The random Variable X follows binomial distribution

= 0.929385

Mean and variance of bulbs in a string that are not lightning properly is given by

Mean of binomial distribution or E(X) = n*p = 20*0.08 = 1.6

Variance of binomial distribution or V(X) = n*p*(1-p) = 20*0.08*0.92 = 1.472

Sindrei [870]

Answer:

12 bananas or 8 apples are needed to purchased

Explanation:

The computation of the number of bananas or the apples is shown below:

Since the income is $24

And, the price of an apple and the price of banana is $3 and $2 respectively

So, the number of bananas is

= $24 ÷ $2

= 12 bananas

And, the number of apples is

= $24 ÷ 3

= 8 apples

Therefore 12 bananas or 8 apples are need to purchased

d. Suppose that the increase in input price does not occur but, instead, that productivity increases by 25% percent. What would
worty [1.4K]

Answer:

decreased by 20%

Explanation:

Supposed we have input price of $30,000 and it produced an output of 300 units on the first year of operation. The cost per unit on the first year is $100 each ($30,000/300).

On the second year we still have the same input expense of $30,000 but the productivity output increased by 25%. So we have 375 units produced on the second year’s operation. The new cost per unit would be $30,000/375=$80 per unit.

Therefore we conclude that based on the example given, the new unit cost per product decreases by 20%.

$100-80 = $20

$20/$100 = 20%

Which of the following changes in the loanable funds market will decrease the equilibrium real interest rate?
LuckyWell [14K]

Answer:

The answer is Option C

Explanation:

Any event that would either decrease the demand for loanable funds or increase the supply of loanable funds will decrease the equilibrium interest rates. Supply of loanable funds is affect by the amount of national savings. National savings in turn, is the sum of private savings, public saving and net capital inflow.

In option C, capital inflows are increasing. This means that there would be an excess supply of money in the economy which can be converted into loanable funds. This would, therefore, push the supply curve to the right thereby reducing the real interest rate equilibrium.

Answer:

(C) debit to Foreign-Currency Transaction Loss-$1040

Explanation:

Foreign currency related Financial assets and financial liabilities are usually revalued with any difference as a result of the exchange rates posted as a gain or loss in the income statement.

On transaction date, cost of assets

= 520000 * $0.034

On payment date, the amount paid

= 520000 * $0.036

The amount paid is higher than the liability recorded before hence the difference is recognized as a loss on foreign exchange.

= 520000 * $0.036 - 520000 * $0.034

= $1040
