\bf \textit{volume of a rectangular prism}\\\\
V=Lwh~~
\begin{cases}
L=\stackrel{depth}{length}\\
w=width\\
h=height\\[-0.5em]
\hrulefill\\
h=7\\
w=4\\
V=28
\end{cases}\implies 28=L(4)(7)\implies \cfrac{28}{(4)(7)}=L\implies 1=L

Find the mean median range and mode for 3, 3, 4, 8, 9, 10, and 12
Alexeev081 [22]

Answer:

Mean: 7

Median: 8

Range: 9

Mode: 3

Step-by-step explanation:

First, to find the mean of a set of numbers you need to add up all of the numbers and divide that by the total amount of numbers. In this case that makes this equation, \frac{3+3+4+8+9+10+12}{7}, which is \frac{49}{7}, which is 7.

To find a median you need to find the middle number. A handy trick I use for this is to place my fingers on the first and last number, and then move them towards the middle, at the same time by one number until there is just one number left in the middle. If there are no numbers left after doing this, meaning there are an even amount of numbers given, the median is the mean of the last two numbers that were covered. In this case, this is not necessary, so the median is 8.

The range is the difference between the maximum and minimum of a data set. In this case that would give you the equation Range=12-3, which means the range is 9.

Finally, the mode is the number that occurs the most in a given data set. In this case the number that occurs the most is 3, which occurs twice compared to every other number which only occurs once.
