Answer:
The answer is option A) <em>r</em><em> </em>and <em>s</em>
First, we calculate for the effective interest given the
annual interest and the condition that it is compounded monthly.
<span> Ieff = (1
+ 0.0925/12)^12 – 1 = 0.09652</span>
The equation that would best represent the value of
Grace’s money after x years is equal to,
<span>
An = ($1000)(1.09652)^x</span>
<span>Where x is the number of years</span>
Answer:
(a) 1024 ways
(b) 243 ways
Step-by-step explanation:
When answers are independent, the total number of ways all questions can be answered is the product of the number of ways each question can be answered.
__
<h3>(a)</h3>
The first question can have one answer 4 ways. The second question can be answered 4 ways for each of the ways the first question was answered. That is, the two questions can be answered 4×4 = 16 ways. Similarly, each additional question multiplies the number of ways the questions can be answered by 4.
The 5 questions can be answered 4×4×4×4×4 = 4^5 = 1024 ways.

<h3>(b)</h3>
There are 3 ways to answer the first question incorrectly. Each additional question can be answered incorrectly 3 ways for each of the ways previous questions were answered. The total number of ways all questions can be answered incorrectly is ...
3^5 = 243
A student can answer all questions wrong in 243 different ways.
