1) 99 is correct
2) I would call it a change of +3, since the water level rose going from summer to winter.
He has a total of 378 points now.
Total possible for 5 tests is 500 points.
0.92 * 500 = 460 needed for 92%
460 - 378 = 82% needed on next test.
2) The difference is 3 meters
for no 1)
I'm confused the data is:
86 96 88 91 which = 361
with a test score of 99
added in its;
86 96 88 91 and 99 = 460 /5 = 92%
and i dont understand how you get 3 meters
i got -3 meters
-2 + -1 = -3
I'm sorry. I was wrong for number 1. I added the wrong group of numbers.
DrWLS is right (as usual) :-)
OK SO 1ST ONE IS 99
I Still dont understand how its +3 difference?
can you explain?
It was 2 meters below normal at the end of the summer. It was 1 meter ABOVE normal at the end of winter. The water rose 3 meters in the intervening months.
OK I get it now
