Answer 2

`\huge\textsf{Hey there!}`

`\bullet \large\textsf{ Finding the mean you have to add up all of your numbers \& divide it}\\\large\textsf{by the total numbers in your data plot}`

`\mathsf{(20 + 5 + 45 + 90 + 60 + 45 + 30 + 10 + 20+ 45 + 15 + 25)/(12)}`

`\mathsf{20 + 5 + 45 + 90 + 60 + 45 + 30 + 10 + 20+ 45 + 15 + 25}`

`\mathsf{= 25 + 45 + 90 + 60 + 45 + 30 + 10 + 20 + 45 + 15 + 25}`

`\mathsf{= 70 + 90 + 60 + 45 + 30 + 10 + 20 + 45 + 15 + 25}`

`\mathsf{= 160 + 60 + 45 + 30 + 10 + 20 + 45 + 15 + 25}`

`\mathsf{= 220 + 45 + 30 + 10 + 20 + 45 + 15 + 25}`

`\mathsf{= 265 + 30 + 10 + 20 + 45 + 15 + 25}`

`\mathsf{= 295 + 10 + 20 + 45 + 15 + 25}`

`\mathsf{= 305 + 20 + 45 + 15 + 25}`

`\mathsf{= 325 + 45 + 15 + 25}`

`\mathsf{= 370 + 15 + 25}`

`\mathsf{= 385 + 25}`

`\mathsf{= \bf 410}`

`\mathsf{= (410)/(12)}`

`\mathsf{(410)/(12) \approx \bf 34.1667}`

`\boxed{\boxed{\huge\textsf{Thus, your ANSWER is: \boxed{\mathsf{ \bf \underline{{\star 34.1667\star}}}}}}}}\huge\checkmark`
