Given
A group of children 6 to 10 years old were asked how many video games they owned.
The scatter plot shows the results.
<h3>What is the range?</h3>The range is the difference between the lowest and highest numbers in a data set.
The range of video games owned for the cluster is 8 to 10.
Therefore,

Answer:
The car must have a speed of 25 kilometres per hour to stop after moving 7 metres.
Step-by-step explanation:
Let be , where
is the stopping distance measured in metres and
is the speed measured in kilometres per hour. The second-order polynomial is drawn with the help of a graphing tool and whose outcome is presented below as attachment.
The procedure to find the speed related to the given stopping distance is described below:
1) Construct the graph of .
2) Add the function .
3) The point of intersection between both curves contains the speed related to given stopping distance.
In consequence, the car must have a speed of 25 kilometres per hour to stop after moving 7 metres.
