Question

a survey was given to people who owned a certain type of car.what percent of the people surveyed were completely satisfied with the car.blue:compleletely satisfiedpurple: somewhat satisfiedgreen:not satisfied

Answer 1

The percent of people that were completely satisfied (%PS) can be calculated with the formula:

`\text{ \%PS=}(PS)/(TP)*100\text{\%}`

Where PS is the number of persons that were completely satisfied and TP is the total number of persons, in this case, the total number of persons is the sum of each number of persons from each category:

`TP=160+740+1100=2000`

And as we can see from the figure, the number of completely satisfied people is 1100, then the percent of people that were completely satisfied is:

`\begin{gathered} \text{\%PS=}(PS)/(TP)*100\text{\%} \\ \text{\%PS=}(100)/(2000)*100\text{\%} \\ \text{\%PS=}0.55*100\text{\%}=55\text{\%} \end{gathered}`

The percent of people that were completely satisfied is 55%

You just have to divide 1100 by the total people which is 2000, and then just multiply by 100, and that's it
