yes, but the only change I would make is to write 0.1666 as 1/60 instead

Answer 7

\[\sum_{i=1}^{4}\]
is the total of those 4 partial sums

Answer 8

so I calculated all of them, then summed them in the end

Answer 9

Yes, your first calculation says
\[\sum \frac{ 1 }{ 3 }\]
which is 1/3, the summation of 1/3

Answer 10

you did it correct, just the notation is slightly off

Answer 11

Oh okay okay. Thank you !

Answer 12

The first one is maybe, for i=1
\[f(x _{1},~y _{1}) = 1/3\]

Answer 13

not 1/3 sorry, the -10.67 you got

Answer 14

and you are finding the summation for i=1 to i=4
\[\sum_{i=1}^{4}f(x _{i}~,y _{i})\]

Answer 15

goodluck
