Answer:
The total length would be [tex]2\frac{1}{4}\ inches.[/tex]
Step-by-step explanation:
The line plot figure is missing in the question, so below is the figure attached.
Now, to find the total length, if Kara lines up all the [tex]\frac{3}{4}[/tex] inch buttons.
So, from below figure we see that in the line plot [tex]\frac{3}{4}[/tex] inch buttons represents 3 buttons.
Length of buttons = [tex]\frac{3}{4}[/tex] inch.
Number of buttons = 3.
Now, to get the total length of [tex]\frac{3}{4}[/tex] inch buttons we multiply length of buttons by number of buttons:
[tex]Total\ length=Length\ of\ buttons\ \times\ number\ of\ buttons[/tex]
[tex]=\frac{3}{4} \times 3[/tex]
[tex]=\frac{9}{4}[/tex]
[tex]=2\frac{1}{4} \ inches.[/tex]
Therefore, the total length would be [tex]2\frac{1}{4}\ inches.[/tex]
