A survey was conducted regarding the number of automotive vehicles owned per household. The results of the survey are as follows:\(\begin{array}{c|c} \text{Vehicles}&\text{Households}\\ \hline 0&3\\ 1&9\\ 2&10\\ 3&2\\ 4&1\\ \end{array}\)

Express the average number of vehicles per household as a decimal rounded to the nearest tenth.

Take each line and multiply it  and sum them      0 *3      +    1*9     +     2*10      etc  

    then divide by the total of the second column   3 +  9 + 10 ......
