Answer:
Step-by-step explanation:
After 6 weeks........................16,800 gallons left
10 weeks.......................5,600 gallons
this means that in 4 weeks they used 16,800-5,600=11,200 gallons
11200/4=2,800/week
5600/2800=2
10+2=12
we have 12 weeks of dry season
Because all outcomes are equally weighted, the probability you are looking for is given by :-
Number of favorable eventsTotal number of events
Number of favorable events
Total number of events
In your case: 6 or Even outcome={2,4,6}
6
or Even outcome
=
{
2
,
4
,
6
}
and Outcomes={1,2,3,4,5,6}
Outcomes
=
{
1
,
2
,
3
,
4
,
5
,
6
}
Hence:
Number of favourable eventsTotal number of events=36=12
Answer:no, there are always other ways. LIke this y> x.
Step-by-step explanation:
I use schoology too
Let n represent the number.
.. (n -9)^2 = n -3 . . . . . the square of 9 less than the number is 3 less than the number
.. n^2 -18n +81 = n -3
.. n^2 -19n +84 = 0
.. (n -7)(n -12) = 0
.. n = 7 or 12
The number could be 7 or 12.
_____
Check:
.. (7 -9)^2 = (-2)^2 = 4 = 7 -3 . . . . answer checks OK
.. (12 -9)^2 = 3^2 = 9 = 12 -3 . . . . answer checks OK
