oh.

Answer 6

The sentence just doesn't make sense to me.

Answer 7

I don't get what it's asking. D:

Answer 8

I think that your exercise is asking for the best value of the quantity which is represented by your distribution
here is the value of the weighted average:
\[\frac{{2 + 3 + 2 \times 3 + 2 \times 4 + 3 \times 5 + 4 \times 6 + 3 \times 7 + 3 \times 8 + 2 \times 9 + 11}}{{22}}\]

Answer 9

i got 65920.590909 :/

Answer 10

Could it just be 66 (i rounded)

Answer 11

no, please here are more steps:
\[\begin{gathered}
\frac{{2 + 3 + 2 \times 3 + 2 \times 4 + 3 \times 5 + 4 \times 6 + 3 \times 7 + 3 \times 8 + 2 \times 9 + 11}}{{22}} = \hfill \\
\hfill \\
= \frac{{5 + 6 + 8 + 15 + 24 + 21 + 24 + 18 + 11}}{{22}} = \hfill \\
\hfill \\
= \frac{{34 + 69 + 29}}{{22}} = \frac{{132}}{{22}} = ... \hfill \\
\end{gathered} \]

Answer 12

Answer 14

it is 6

Answer 15

:D Yay! Just curious, how did you get all those numbers?

Answer 16

Sorry I have made an error, in reading your values, here is the right weighted average:
\[\begin{gathered}
\frac{{1 + 2 + 2 \times 3 + 2 \times 4 + 3 \times 5 + 4 \times 6 + 3 \times 7 + 3 \times 8 + 2 \times 9 + 11}}{{22}} = \hfill \\
\hfill \\
= \frac{{3 + 6 + 8 + 15 + 24 + 21 + 24 + 18 + 11}}{{22}} = \hfill \\
\hfill \\
= \frac{{32 + 69 + 29}}{{22}} = \frac{{130}}{{22}} = ... \hfill \\
\end{gathered} \]

Answer 17

1) 49426.0454545
2) 5.909090
3) 5.909090
4) 5.9090
