mean

[marble sand]

How do I solve this <@&791435371564892232>

[burnt bluff]

mean is found by adding all the numbers and dividing by how many there are right

[marble sand]

Yes

[burnt bluff]

so the mean is

sum of the 5 people's ages + ages of 3 other people / 8

and this is equal to 19.5

[marble sand]

Mhm

[burnt bluff]

sum of the first five is 103

and the other 3 can be x

so 103 + x / 8 = 19.5

[marble sand]

I understand so far

[burnt bluff]

so now just find x

[marble sand]

X = 53

I think

[burnt bluff]

mhm

[marble sand]

And do I just divide it by 3

[burnt bluff]

yep
