Answer: 140 square units.
Step-by-step explanation:
The area of triangle with vertices is given by
Then area of triangle QRS with vertices (6,10), (2,-10) and (-9,5) is given by :-
The answer to the question is 1,059.512195
Probability simplified is almost like asking how much are you likely to do something,in this case; select a certain color of marbles.
The Probability of choosing a red marble is 4 expressed as a numerator to the total number of marbles.(4/12---> 1/3)
Green- (3/12---> 1/4)
Yellow- (5/12)
For this question you don't even have to calculate the probability. You're most likely to select the yellow ones because they're the majority.
Hope this helped:)
