Song lengths (minutes) 3.2 3.5 3.2 3.8 7.2 4.2 3.4 3.5 3.5

Find the mean, median, and mode of the lengths.

Mean: 3.94

Median: 3.5

Mode: 3.5

Step-by-step explanation:

Mean:

Add all of the numbers and divide that sum by the number of numbers in the data set

Add:

3.2 + 3.5 + 3.2 + 3.8 + 7.2 + 4.2 + 3.4 + 3.5 +3.5 = 35.5

Divide:

35.5/9 = 3.94

Divide by 9 because there are nine numbers in the data set

Mean: 3.94

Median:

Line up all of the numbers from least to greatest and find the middle

Order:

3.2, 3.2, 3.4, 3.5, 3.5, 3.5, 3.8, 4.2, 7.2

Find the middle:

3.2, 3.2, 3.4, 3.5, 3.5, 3.5, 3.8, 4.2, 7.2

Median: 3.5

Mode:

The most common number in the data set

Look for the most common number:

3.2, 3.2, 3.4, 3.5, 3.5, 3.5, 3.8, 4.2, 7.2

Since '3.5' is featured three times, it is the mode.

Mode: 3.5

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested
