Bob has to own his land for 18 years if the price is increasing at the rate of 6% per year.
Given that land was bought by Bob for $16390, the price is increasing at the rate of 6%, price of land today is $46817.
We are required to find the time for which Bob need to own the land so that the price of the land is $46817 today.
Compounding means calculating amount on the principal and the amount added interest.
Rate of increasing the price of land be 6%.
Price when Bob bought the land=$16390.
Price of land today=$46817.
It is like compounding of interest and the sum is calculated as under:
S=P*
In the above equation P is theamount at beginning,r is rate of increasing and n is the number of years.
46817=16390
46817/16390=
=2.8564
=
(Approximately)
From both the sides we will get n=18.
Hence Bob has to own his land for 18 years if the price is increasing at the rate of 6% per year.

The marginal tax rate is the rate paid on the last dollar of income; this would be whatever tax bracket the family is in. The average price is the total tax divided by the total revenue. </span><span>
Family A: </span><span>
</span><span>
total income $40,000: this includes $10,000 at 0%, $20,000 at 10% (tax of $2,000), and $10,000 at 20% (tax of $2,000). The last rate paid is 20% so that is the marginal rate; the total tax paid is $4,000, divide that by $40,000 total income, that is the average rate. </span><span>

total income $100,000: this includes $10,000 at 0%, $20,000 at 10% (tax of $2,000), $20,000 at 20% (tax of $4,000), $30,000 at 30% (tax of $9,000), and $20,000 at 40% (tax of $8,000). The last rate paid is 40% so that is the marginal rate; the total tax paid is $23,000, divide that by $100,000 total income, that is the average rate.</span>
Answer:
A) discrete random variable.
Explanation:
Discrete random variables can assume only a finite number of values, and their combined total probabilities must equal 1.
On the other hand, continuous random variables can take any value with an interval or collection of intervals, which means that the possible values are infinite.
A complex random variable is a combination of two real random variables that have rel and imaginary parts.
Answer:According to the article, when companies earn patents specifically to prevent competition, it hinders the innovation of products that might actually be better. For instance, Bruce Nolop describes how his company had to pay more attention to the "minefield of existing patents than on the expected value that we could bring to customers." Rosabeth Moss Kanter suggests a "use it or lose it" solution to this problem. She thinks that a company that patents an item would be forced to use the patented idea or product or risk losing the patent. This idea would encourage more competition and prevent patent abuse.
