A line plot is a data display, along a number line, which shows frequency.
The frequency is indicated by a marker, like an X or a dot.
First, find the totals for each length.
There are 2
x's above
feet. Multiply
feet by 2.
ft × = ft × = ft = ft
There are 4
x's above
feet. Multiply
feet by 4.
ft × = ft × = ft = ft = ft
There are 3
x's above
feet. Multiply
feet by 3.
ft × = ft × = ft = ft
There are 2
x's above
feet. Multiply
feet by 2.
ft × = ft × = ft = ft
Now, find the sum of all of the totals.
ft + ft + ft + ft |
= |
ft + ft + ft + ft + ft + ft |
|
= |
ft + ft + ft |
|
= |
ft + ft + ft |
|
= |
ft + ft |
|
= |
ft + ft |
|
= | ft |
So, if placed end-to-end, the total length of all of the compact cars would be feet.
