Using the simple interest formula, it is found that the APR for the loan is of 4.472%.
<h3>What is the simple interest formula and when it is used?</h3>Simple interest is used when there is a single compounding per time period.
The amount of money after t years in is modeled by:
In which:
- A(0) is the initial amount.
- r is the interest rate, as a decimal.
The parameters for this problem are:
A(t) = 6 x 511.18 = 3067.08, A(0) = 3000, t = 0.5.
We solve the equation for r to find the APR.
1 + 0.5r = 1.02236
r = (1.02236 - 1)/0.5
r = 0.04472.

Answer:
a. 7893600
Step-by-step explanation:
Given that there are 26 numbers out of which 5 numbers are to be chosen.
Here repetition is not allowed.
For each of the 5 cases, the total number of possibilities will keep on decreasing by 1.
1st case, number of possibilities = 26
2nd case, number of possibilities = 25
3rd case, number of possibilities = 24
4th case, number of possibilities = 23
5th case, number of possibilities = 22
a. Total number of possibilities = 26 25
24
23
22 = <em>7893600</em>
b. Probability of winning by choosing one number:
Formula for probability of an event E can be observed as:
Number of favorable cases = 1
Total number of cases = 26
So, required probability:
So, the answers are:
a. 7893600
