The two main properties of sound are frequency and amplitude. The frequency of the sound waves determines the pitch of the sound. The amplitude of sound determines the loudness. The quality of sound is affected by the pitch and the loudness.
Linear equations are used to represent relations that have constant rates
The linear regression equation that models the data in this table is 
<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:
Where:
and 
So, we have:
Also, we have:
Hence, the linear regression equation is:

Answer:
The correct answer is - Anaphase.
Explanation:
Cell division can be either mitosis or meiosis. Mitosis cell division has these phases:
A. Interphase - non-dividing phase with to G1, S and G2 sub phase. In this genetic material doubles and cell size increases.
B. Prophase- chromosomes shorten and condense by coiling. Centrioles move in opposite directions.
C. Metaphase - spindle fibres bind to kinetochores and pulls it the chromosomes on the equator of the spindle forms a plate called the metaphase plate.
D. Anaphase- these get condense and centromeres split into two and the spindle fibres pull the daughter centromeres to opposite poles.
E. Telophase is the last phase of Mitosis.
The answer is chemical energy
