Answer:
y = -2.5 + x
Explanation:
Given the data:
__X____Y
$20 __$17.50
$21 __ $18.50
$22__ $19.50
$23__ $20.50
Using a linear regression calculator :
The linear regression model obtained is :
y = -2.5 + x
Where ; - 2.5 = intercept ; gradient / slope = 1
Burning fossil fuels emits a number of air pollutants that are harmful to both the environment and public health. Sulfur dioxide (SO2) emissions, primarily the result of burning coal, contribute to acid rain and the formation of harmful particulate matter.
However, the use of solar panels is environment friendly. Solar power is renewable at absolutely no cost to supply energy infinitely. Also, it is very low maintenance. Once installed, the solar power system can last twenty to thirty years.
Similarly wind (turbines) and water (hydroelectric power plants) are an endless source of energy without negatively affecting the environment.
Answer:
Explanation:
Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions. And The difference between Applied and Pure Sciences is that Applied Sciences focuses on the scientific knowledge of nature, it is more related to engineering and technology. Pure sciences is more related to theories and predictions to understand the world of nature, often performed in a laboratory.
