Answer: i don't think that this is a school question please ask school related questions have a great day
Step-by-step explanation:
Maybe 2/2 I’m not sure. Sorry if it’s wrong.
Total up the number calls that each point suggests(y coordinates).
0+2+5+9+4+3+9+6+2+0 = 40 calls
Didn’t get the full problem, what is z equal to?
What we know here is that all 2500 shares together are worth 100 000 dollars in total. (it's 100 000.00 actually, but we can ignore the part after the point, as it's equal to 0).
This means that each of the shares is valid the whole sum divided by the number of shares, that is:
(first i divided both denominator and numerator by 100)
So each value is worth 40 dolars.
