Answer:
mean is 5
Step-by-step explanation:
<h2>
MEAN</h2>
mean is regarded as the average number of items
<h3>mean formula:</h3>
<em>(sum of terms) / (number of terms)</em>
<h3><u /></h3><h3><u>Firstly</u></h3>
the numbers in the data set are :
3,3,3,4,6,6,7,8
they are already arranged in order, so no need to rearrange.
<h3><u>Next </u></h3>
add the numbers together to find the total :
3 +3 +3 +4 +6+ 6+7 +8
= 40
ALSO,
find how many number of terms they are --- this is 8
Last
use the mean formula to solve :
<em>(sum of terms) / (number of terms)</em>
= 40/8
= 5
<h3><em>
<u>the mean is the 5 </u></em></h3>

Answer:
$1,229.75
Step-by-step explanation:
Lets use the compound interest formula provided to solve this:
<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First, change 3.25% into a decimal:
3.25% -> 
-> 0.0325
Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:
Lastly, subtract A from P to get the interest earned:
