$\displaystyle 1\frac{1}{13} \times 7 = 7\frac{7}{13} ≈ 7,538461538 ≈ 7,5$

$\displaystyle \frac{41}{1\frac{1}{10}} = 37\frac{3}{11} ≈ 37,3$

I need help with math if you don't know the answer get out of the question and don't answer it and give the wrong answer or some

Answer:

Step-by-step explanation:

Frequency table for the height of the seedlings,

Height (in inches) Number of seedlings

$\frac{1}{2}$ 2

$\frac{3}{4}$ 4

$\frac{5}{8}$ 2

$\frac{7}{8}$ 2

Now we can draw the line plot as attached.

Average height of the seedlings = $\frac{2(\frac{1}{2})+4(\frac{3}{4})+2(\frac{5}{8})+2(\frac{7}{8})}{2+4+2+2}$

= $\frac{1+3+1.25+1.75}{10}$

= $\frac{7}{10}$
