When constructing a graph that compares the land areas of the five largest countries, you choose to depict the five areas with s
quares of different sizes. If the squares are drawn so that the areas are in proportion to the areas of the corresponding countries, is the resulting graph valid? Why or why not? No, using area in graphs is always misleading.
Since we know that the area of a land of five largest countries is two-dimensional.
Also , if we are using a square figure which is also two-dimensional in order to describe the area of land then it would be valid because we just used a mathematical model of equal dimension to describe these lands.
If you are making a graph about the area of a country, that is a two dimensional measurement. It would be ok to make a graph that is also 2 dimensional.
Given that the number is x, 10% increase will give us a new number of: 110/100*x =1.1x 10% decrease will give us a new number of: 90/100*1.1x =0.99x This implies the new number is less than the original number
