Answer:
Yellow.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes. Experimental probability is found taking into account previous experiments.
In this question:
6 + 5 + 4 + 10 = 25 total marbles.
The experimental probabilities are:
6/25 probability it is red.
5/25 = 1/5 probability it is yellow. Thus, the answer is yellow.
4/25 probability it is blue.
10/25 = 2/5 probability it is green.
Answer:
Roy is 6 years old and Aaron is 1 year old.
Step-by-step explanation:
A is Aaron's age,
R is roy's age,
A = R - 5
R + 4 = 2(A+4)
We can distribute first,
R + 4 = 2A + 8
Subtract 4 from each side,
R = 2A + 4
Since A = R - 5, you can substitute in R - 5 for A in the equation,
R = 2(R-5) + 4
Distribute,
R = 2R - 10 + 4
Since - 10 + 4 = -6, we can do this,
R = 2R - 6
Subtract R from both sides,
0 = R - 6
Add 6 to both sides and you have part of your answer;
R = 6
Since A = R - 5,
A = 6 - 5
A = 1, so Aaron's age is 1.
