Answer:
sopomores= 0.0397
juniors= 0.1481
seniors= 0.2063
Explanation:
Giving the following information:
There are two teams of students:
Team A with 3 sophomores, 8 juniors, and 13 seniors. Total of 24 students.
Team B with 5 sophomores, 7 juniors, and 6 seniors. Total of 18 students.
First, we need to calculate the probability of selecting any student on each team:
Team A:
sophomores=3/21= 0.1428
juniros= 8/21= 0.3809
senors= 13/21= 0.619
Team B:
sopomores= 5/18= 0.2778
juniors= 7/18= 0.3889
seniors= 6/18= 0.3333
Now, we can calculate the probability of selecting the same type of students:
sopomores= 0.1428*0.2778= 0.0397
juniors= 0.3809*0.3889= 0.1481
seniors= 0.619*0.3333= 0.2063
Answer:
Option C, Its marginal tax rate is 18.33%. is correct
Explanation:
The tax payable on its first $50,000 of income is shown below:
tax payable=$50,000*15%=$7500
The tax payable on the remaining balance of $25,000 is computed thus:
tax payable on the balance of $25,000=$25,000*25%=$6250
Total tax payable=$7,500+$6,250=$ 13,750.00
Marginal tax rate=tax payable/taxable income=$ 13,750.00/$75,000=18.33%

Explanation:
The supply-and-demand analysis is one of the most basic principles in economics. In simple terms, it states that when an item is scarce, but many people want it, the price of that item will rise. The theory can be applied to markets of <em>goods and services, labor, capital, </em>and <em>all the factors of production</em>. It could be useful to study the fluctuations of a firm or the overall economy.
