Step-by-step explanation:
List them all out
Here it goes:
a. Because you have four blue marbles out of the 12 total marbles, the probability is 4/12. YOU MUST SIMPLIFY down to 1/3.
b. There are 12 marbles in the bag right now, and the probability is 4/12, you must add some marbles. 1/10 multiplied by 4 is 4/40. There are 4 blue marbles right now, and 40 minus the 12 there are right now is 38, so you would need to add 38 non-blue marbles.
Answer: 188 children and 200 adults were admitted.
Step-by-step explanation:
Let x represent the number of children that were admitted that day.
Let y represent the number of adults that were admitted that day.
On a certain day, 388 people entered the park. It means that
x + y = 388
The admission fee at the amusement park is $2.00 for children and $6.80 for adults. The admission fees collected that day totaled $1736. It means that
2x + 6.8y = 1736- - - - - - - - - - - 1
Substituting x = 388 - y into equation 1, it becomes
2(388 - y) + 6.8y = 1736
776 - 2y + 6.8y = 1736
- 2y + 6.8y = 1736 - 776
4.8y = 960
y = 960/4.8
y = 200
x = 388 - y = 388 - 200
x = 188
