The study design used in this scenario is an Epidemiological study design/ Epidemiologic study design. This type of study compares 2 groups whose characteristics are the same except for one factor. This type of study is usually used in the medical field. The purpose of a study design such as this is to determine if a factor is associated with health defects or injury.
Answer:
Nico invest $2500 at 9% interest rate and $800 at 4% interest rate.
Explanation:
He invests some money at 9%, and $1700 less than that amount at 4 %.
Let Nico invest $x at 9%.
It means he invest $( x-1700) at 4%.
The investments produced a total of $257 interest in 1 yr.




Add 68 on both sides.


Divide both sides by 0.13.

Nico invest $2500 at 9% interest rate.

Nico invest $800 at 4% interest rate.
Therefore Nico invest $2500 at 9% interest rate and $800 at 4% interest rate.
Answer: purchase foreign currency in order to purchase a U.S. treasury bond.

Currency convertibility has to do with the degree in which the domestic currency of a particular country can be converted into the currency of another country.

Answer:
invoice price (dirty price) = $1,004.13
Explanation:
semi-annual coupon = $1,000 x 7% x 1/2 = $35
clean price = $1,001.25
accrued interest = (Jan. 30 - Jan. 15) x $35 x 1/182 = $2.88
invoice price (dirty price) = clean price + accrued interest = $1,001.25 + $2.88 = $1,004.13
the dirty price or invoice price of a bond includes any accrued interest that the bond may have earned in the period between the last coupon payment and the transaction date.
Answer: D. will be less than the intrinsic value of stock Y
Explanation:
Based on the information given above, the intrinsic value of Stock X will be calculated thus:
D1 = Dividend in next year = $3
g = growth rate = 7%
r = = 13%
Therefore, intrinsic value of Stock X will be:
= D1 / (r-g)
= 3 / (13% - 7%)
= 3/6%
= 3 / 0.06
= $50
Therefore, the intrinsic value of stock X is $50.
Intrinsic value of Stock Y will b calculated thus:
D1 = $4
g = 7%
r = 13%
Intrinsic value of Stock Y will be:
= D1 / (r-g)
= 4 / (13% - 7%)
= 4/6%
= 4 / 0.06
= 66.67
Intrinsic value of Stock Y is $66.67
Therefore, the intrinsic value of Stock X will be less than the intrinsic value of Stock Y
