Answer:
Probabilty of winning the next two matches in a row = 1/9
Step-by-step explanation:
The total number of possible outcome = 3
(Win, lose, draw)
The probability of obtaining a win in a single match = 1/3
The probability of winning in two rows is 1/3² = 1/9
The explicit formula for the geometric sequence is
Step-by-step explanation:
The formula of the nth term of a geometric sequence is
, where:
- a is the first term of the sequence
- r is the common ratio between the consecutive terms
The geometric sequence of is 6 , -2 , , ,
∵ = 6
∵
∵ = -2
∴
- Divide both term by 2 to simplify it
∴
∵
- Substitute the value of and r in the rule above
∴
The explicit formula for the geometric sequence is

Answer:
Step-by-step explanation:
for it to be a solution, it has to satisfy both inequalities....not just one
y > x.......(-1,2)....x = -1 and y = 2....now we sub
2 > -1.....2 is greater then -1......this is true
x + y > 0....(-1,2)...x = -1 and y = 2.....sub
-1 + 2 > 0
1 > 0......1 is greater then 0....this is true
so (-1,2) IS a solution to this system because it satisfies both inequalities
