Answer 2

`\huge\text{Hey there!}`

`\large\text{The mean of a particular data plot is known as your average. To find}\\\large\text{the mean/average you have to ADD of the numbers \& DIVIDE them}\\\large\text{by the total numbers it has in the plot.}`

`\text{Here's the formula: }\rm{(Sum\ of\ all\ your\ numbers\ in\ the\ plot)/(Total\ number\ in\ the\ data\ plot)= your\ average/mean`

`\huge\text{LET'S SOLVE FOR THE QUESTION}`

`\large\text{The equation: }\bf{(80 + 81 + 82 + 83 + 84 + 85 + 86)/(7) = mean/average}\\\\\bf{= (161 + 82 + 83 + 84 + 85 + 86)/(7)}\\\\\bf{= (243 + 83 + 84 + 85 + 86)/(7)}\\\\\bf{= (326 + 84 + 85 + 86)/(7)}\\\\\bf{= (410 + 85 + 86)/(7)}\\\\\bf{= (495 + 86)/(7)}\\\\\bf{= (581)/(7)}\\\\\bf{= 581/7}\\\\\bf{= 83}`

`\huge\textbf{Therefore, your answer is: \boxed{\mathsf{83}}}\huge\checkmark`
