Answer:

50 A alleles

Explanation:

Since the question only wants information regarding the homozygous AA group, the information pertaining the other two groups may be disregarded.

Each individual with the AA genotype has two A alleles. Therefore, if there are 25 individuals that are homozygous AA, the number of A alleles in this group is:

n = 25*2=50\ A\ alleles

There are 50 A alleles in in the homozygous AA group.

A problem that the Fed faces when it attempts to control the money supply is that a. since the U.S. has a fractional-reserve ban
NeTakaya

Answer:

A) since the U.S. has a fractional-reserve banking system, the amount of money in the economy depends in part on the behavior of depositors and bankers.

Explanation:

Since US banks operate under a fractional reserve banking system, they have the capacity to create money through the money multiplier, e.g. you deposit $1,000 in bank A, then bank A borrows $850 to Steven and he purchases a new bike from Sarah. Then Sarah deposits the money in bank B, and bank B borrows $722 to George who buys a laptop from Henry. Henry then deposits the money in bank C, and bank C borrows $614 to Susan, and this goes on and on.

The problem that the Fed faces is that in order for the fractional reserve system to work, households must hold their money in banks. Ans that is something that the government cannot control, specially the amount or portion that is deposited. The other players are banks, that ideally should borrow all the money that they are allowed to.

Answer:

The IRR is 10%.

Explanation:

a) Calculation of Internal Rate of Return (IRR):

We choose a discount rate, say 10% and use it to discount the cash flows to their present values.  If the net present value (NPV) of all the cash flows equals zero, then that discount rate is accepted as the IRR.

b) Without 10% discount rate, the discount factors are for:

1st year = 1.1 (1 + discount rate) raised to power 1

2nd year = 1.21 (1 + discount rate) raised to power 2

3rd year = 1.331 (1 + discount rate) raised to power 3

c) These discount factors will divide the cash inflows for each year:

1st year, NPV = $15,364/1.1 = $13,967.27

2nd year, NPV = $15,364/1.21 = $12,697.52

3rd year, NPV = $15,364/1.331 = $11,543.20

Total NPV of inflows                 = $38,209 approximately

NPV of outflows                         -$38,209

NPV of inflows and outflows      $0

So, the IRR is 10%.

IRR is a capital budgeting metric to measure profitability by using a discount rate which makes the net present value of all cash flows to become zero.  To get a suitable rate, trial and error is involved, or one can make use of educated best guess.

Miguel, a recent​ 22-year old college​ graduate, wants to retire a millionaire. How much will he need to set aside annually to a
olga55 [171]

Answer

Miguel must set aside $62,745 annually

Explanation

N = Number of years till Miguel would retire = 43 years

FV = Future Value = $1,000,000

r = Interest rate = 10%

PMT = Annual payments (at the ending of the year) = ?? The question asks us to calculate this

We would use the future value ordinary annuity formula to calculate PMT

FV = PMT [\frac{(1+r )^{N} -1}{r} ]

1000000 = PMT [\frac{(1+0.10 )^{10} -1}{0.10} ]

PMT ≅ $62,745

Miguel must set aside $62,745 annually

Consider the market for socks. The current price of a pair of plain white socks is $6.00. Two consumers, Jeff and Samir, are wil
muminat

Answer:

consumer surplus = $3.5

producer surplus = $2

Explanation:

Consumer surplus is the difference between the willingness to pay of a consumer and the price of the good.

Consumer surplus = willingness to pay – price of the good

Jeff's consumer surplus = $7 - $6 = $1

Samir's  consumer surplus = $8.50 - $6 = $2.50

total consumer surplus = $1 + $2.50 = $3.50

Producer surplus is the difference between the price of a good and the least price the seller is willing to sell the product

Producer surplus = price – least price the seller is willing to accept

Manufacturer 1's producer surplus = $6 - $4.5 = $1.50

Manufacturer 2's producer surplus = $6 - $5.50 = $0.50

total producer surplus = $1.50 + 0.50 = $2
