Answer:

Total Number of Relays = 100

Number of 5V relays = 60

Number of 10V relays = 25

Number of 15V relays = 15

Probabilities:

All the drawn are 5V relays = 60 / 100 = 0.6

All the drawn are 10V relays = 25 / 100 = 0.25

All the drawn are 15V relays = 15 / 100 = 0.15

At least one is 10V relays = (60 / 100) x (59/99) + (25/100) x (25/99) + (15/100)(15/99)= 0.35758 + 0.06313 + 0.02273 = 0.44344 = 0.44

Answer:

$3

Explanation:

A price floor is when the government or an agency of the government sets the minimum price of a product. A price floor is binding if it is set above equilibrium price.

Price ceiling is when the government or an agency of the government sets the maximum price for a product. It is binding when it is set below equilibrium price.

Equilibrium price is the price at which quantity demand equal quantity supplied. Above equilibrium price there is a surplus - quantity supplied exceeds quantity demanded.

Below equilibrium price there is a shortage - quantity demanded exceeds quantity supplied

Shortage = $12 - $9 = $3

Katen [24]

Answer:

Longly will receive $1,817.43 from selling the bond.

Explanation:

As the coupon rate is 8%; we have annual coupon payment = 2,000 x 8% = $160.

The price of the bond Longly will receive is equal to the present value of 20 annual coupon payment plus the present value of $2,000 face value repayment in 20 years time; with the two streams of cash flow discounting at the market rate at the date of issuing 9%; which is calculated as:

[ ( 160/9%) x [ 1 - 1.09^(-20) ] ] + ( 2,000 / 1.09^20 ) = $1,817.43.

So, the answer is $1,817.43.
