Suppose a perpetuity bond with a face value of $1,000 has a 10% coupon rate. If market interest rates fall to 8%, the price of the bond
A. rises to $1,080.
B. falls to $750.
C. stays at $1,000.
D. rises to $1,250.​

Answers

Answer: rises to $1,250.​

Market Interest rate, i = 8%

The price of the bond will be:

= Annual coupon/Interest rate

= $100/8%

= $100/0.08

= $1250

Therefore, the price of the bond rises to $1,250.​ The correct option is D.

A health insurance policy pays for two medical exams each year and a dental exam. is this insurance in the sense of socializing risk?​

Answers

Answer:

Yes.

Insurance, by its very nature, socializes risks and losses while privatizing profits.

Explanation:

This has been the nature of insurance, health insurance inclusive.  All insurance is about spreading (socializing) the risks so thinly that each affected person does not feel any heavy burden.  A health insurance policy collects some amount of premium in order to cover unforeseen health risks for the insured.  There is no policyholder who pays for the full cost of her policy.  The cost is always spread out to the insuring public.

In counseling and psychotherapy groups, member-to-member contact outside of group often results in _____ and _____. COURSE HERO

Answers

Answer:

subgroups and hidden agendas

Explanation:

According to various research studies on Personal relationships among specialty group members, such as counseling and psychotherapy groups, it was concluded that member-to-member contact outside of the group often results in SUBGROUP and HIDDEN AGENDAS. Most of the time, this can lead to damaging situations. Thus it is considered a sensible strategy to prevent the formation of such subgroups.

While studying how objects change motion when they run into each other, Isaac Newton discovered that the force of an object’s impact equals the object’s mass multiplied by its acceleration.

He could not explain why this is, but it was clearly true to anyone else who conducted experiments, and it remains just as true today.

Is Newton’s statement a law or a theory?

1. It is a theory because it developed and changed over time as new technology provided new observations.
2. It is a theory because it is a statement of fact that does not need any more experimental support.
3. It is a law because it developed and changed over time as new technology provided new observations.
