Mean = Average : Sum of the data ÷ Number of data

So find the average number of lates per student

4 = Lates

30 (sum of frequencies) = Frequencies

The temperature fell by 15 degrees Fahrenheit today.
katrin2010 [14]
<h3>Answer is   -15</h3>

We read this out as "negative 15" or you could write "negative fifteen".

The negative indicates the temperature went down. It doesn't necessarily mean that the final temperature is -15 degrees.

For example, if it starts being 50 degrees F, and drops by 15 degrees, then 50+(-15) = 50-15 = 35 degrees is the temperature after that drop. It might help to use a vertical number line.
