To find the mean:
Take <span>3 4 5 3 4 5 6 5 4 3 2 3 4 5 6 4 8 4 3 2 and add them all together
=83
Now you divide 83 by the number of terms in the sample set, which is 20.
83/20 = 4.15
For rounding to the nearest tenth, look at the hundredths space, which is 5. Since it is 5 or higher, round the tenths up one.

Step-by-step explanation:
To find a percent of a number, change the percent to a decimal and multiply by the number. To change a percent to a decimal, move the decimal point of the percent two places left.
30% of 90 =
= 30% * 90
= 0.30 * 90
= 27
Step-by-step explanation:
Using this formula;
A = P(1 + rt)
A = Amount i.e. $5000
P = Principal or Initial payment
r = rate i.e. 12%
t = 4 years
5000 = P(1 + 0.12 × 4)
5000 = P(1 +0.48)
5000 = P(1.48)
P = 5000 / 1.48
= $3378.378
= $3378
