Why are data organized into tables and graphs

Hey!

Data can be in graphs to show certain results. Such as, a pie graph can show the majority of votes wile data about a plant growing over time, you would use a line graph. Tables can explain rules such as, if the average person in a store buys 5 dollars worth of supplies, then if 7 people are in the store, the average would be 35 dollars.
Hope this helps! Make sure to do research before you submit!

the catch is that the top numbers are atomic masses the bottom numbers are the numbers of protons and electrons in an uncharged atom. they are the number of that atoms as you would find them on the periodic table. further, the numbers on the left are used to determine the missing numbers on the right

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
