A control is the normal behavior you are testing the variable against. There are two types of variables. The independent variable is what you change to test what the dependent variable is, which is the variable that changes due to the independent variable, and what you generally record your data over.

How is the earthworm adapted to its feeding habits
vovikov84 [41]
Hi there,

How is the earthworm adapted to its feeding habits?

Well a earthworms are tube shaped, some worms such as segmented worms can be found in soil.They are there to stay moist and to feed on organic matter.

So an earthworm's<span> digestive tract is laid out straight from the oral orifice to the anus. The parts of the digestive tract regulate or absorb the nutrients from every meal.

</span>Hope this helps!

I used to have a worm farm myself, it was really cool to see really up close on how worms live and how they feed on organic matter in the soil.

Linear equations are used to represent relations that have constant rates

The linear regression equation that models the data in this table is \^y = 2.40476x + 0.33333

<h3>Regression equation using a graphing calculator</h3>

To calculate the regression equation, we make use of a graphing calculator.

Using the graphing calculator, we have the following data:

  • Sum of X = 28
  • Sum of Y = 70
  • Mean X = 3.5
  • Mean Y = 8.75
  • Sum of squares (SSX) = 42
  • Sum of products (SP) = 101
<h3 /><h3>Formulating the regression equation</h3>

The regression equation is represented as:

\^y = b\^x + a

Where:

b = \frac{SP}{SSX} and a = MY - bMX

So, we have:

b = \frac{101}{42}

b = 2.40476

Also, we have:

a = MY - bMX

a= 8.75 - 2.4\times 3.5

a= 0.33333

Hence, the linear regression equation is:

\^y = 2.40476x + 0.33333
