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:

$\^y = 2.40476x + 0.33333$

A large number species on Earth become extinct during a short time period about 65 million years ago. Based on this pattern of e

max2010maxim [7]

Answer and Explanation:

During the whole biota history, there occurred extinctions due to different reasons.

During the Cretaceous, which took place between 145-65 million years ago, there occurred a massive extinction that eliminated most of the species on the Earth. Many of the characteristic groups of this period were affected. Dinosaurs, Plesiosaurs, Ammonites, Tricodonts, Cycas, Gynkgos, Conifers, the recent angiosperms, birds, and mammals.

The extinction was caused by the volcanic eruptions, and the unusual fall of many different asteroids, which caused important changes on the Earth´s surface. The consequent climatic change was what ended affecting all the species directly. The extinction was gradual, although it occurred in a short geological lapse of time.
