Question

I need help to Find the missing percentages and what is the independent and dependent variable.

Answer 1

From the given table;

Where, the November values is used as 100 percent;

To find the missing percentages of Elm leaves

For the month of May

`\begin{gathered} For\text{ the month of November: 3481} \\ For\text{ the month of May;} \\ =(1739)/(3481)*100\%=49.95690\approx50.0\%\text{ \lparen1 decimal place\rparen} \\ For\text{ the month of August} \\ =(35)/(3481)*100\%=1.00545\approx1.0\%\text{ \lparen1 decimal place\rparen} \end{gathered}`

To find the missing percentages of Hazel leaves

`\begin{gathered} For\text{ the month of November:}1723 \\ For\text{ the month of May;} \\ =(501)/(1723)*100=\:29.07719\approx29.1\%\text{ \lparen1 decimal place\rparen} \\ For\text{ the month of August;} \\ =(62)/(1723)*100\%=3.59837\approx3.6\%\text{ \lparen1 decimal place\rparen} \end{gathered}`

What is the independent and dependent variable?

An independent variable is a variable that does not depend on any other variable.

For example,

`3y=4x+1`

x is an independent variable because for every value of x, there is a different value of y

A dependent variable is a variable whose value depends upon an independent variable.

For example;

`y=5x`

From the expression above, the value of y depends on the value of x
