The total growth, in inches, of Isabella's plant is [tex]4\frac{1}2[/tex] inches
From the line plot, the total growth can be represented as:
[tex]Total = \frac 18 * 4 + \frac 28 * 2 + \frac 38 * 3 + \frac 48 * 1 + \frac 58 * 3[/tex]
Evaluate the products
[tex]Total = \frac 48+ \frac 48 + \frac 98 + \frac 48 + \frac {15}8[/tex]
Evaluate the sum
[tex]Total = \frac{4+4+9+4+15}8[/tex]
Evaluate the numerator
[tex]Total = \frac{36}8[/tex]
Evaluate the quotient
[tex]Total = 4\frac{1}2[/tex]
Hence, the total growth, in inches, of Isabella's plant is [tex]4\frac{1}2[/tex] inches
