A- 4/6, B- 3/6
If both events happen, the probability is A*B= 4/6 * 3/6 = 12/36= 1/3
P(AnB)= 1/3
The equation that describes the relation between the number of games (g) and the number of teams (n) is given as follows:
g = n^2 - n
Now, we are given that the number of games is 132. This means that g=132. To know the number of teams, substitute with the given g in the given equation as follows:
g = n^2 - n
132 = n^2 - n
n^2 - n - 132 = 0 .......> factorize this expression
(n-12)(n-11) = 0
This means that:
either n = 12 teams
Or n = -11 teams (this solution is rejected as the number of teams cannot be negative)
Therefore, based on the above calculations, if the number of games is 132, then, the number of teams is 12
Answer:
X=61.2
Step-by-step explanation:
x/85 = 72/100
x*100/8500 = 6120/8500
x*100 must equal 6120 therefore x must be 61.2 because 61.2 * 100 is 6120
Answer:
6:13 or 6/13
Step-by-step explanation:
the total number of marbles is 26
the total number of red marbles is 12
6 to 13
6:13 OR 6/13
<em>(I was not sure if I was supposed to leave it as 12:26 or simplify it to 6:13, but I think 6:13 is more reasonable since it is asking for a ration)</em>
