$\huge\text{Hey there!}$

$\mathsf{7 + 6 - 9 \times(-2) + (-3)}$

$\mathsf{7 + 6 = \bf13}$

$\textsf{\bf 13}\textsf{ - 9 (-2) - 3}$

$\mathsf{9(-2) = \bf -18}$

$\textsf{13 - \bf(-18) }\textsf{- 3}$

$\mathsf{13 + 18 = \bf 31}$

$\mathsf{\bf 31}\textsf{ - 3}$

$\mathsf{\bf 28}$

$\boxed{\boxed{\large\text{ \huge \bf 28}}}\huge\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$

Alright, the mean is the sum of the ages divided by the number of peoplpe

ok, so example

let's say he has 3 people on his team (not realistic but it's an example)
4yr and 7yr and 4yr
3 people

4+7+7=15
15/3=5, mean is 5

if the 7yr old leaves and is replaced witha 6 year old
4+6+4=14
14/3=4.6666666666666666666666666666667
the mean is no longer 5 because one of the values changed
