Answer:
31/40
Step-by-step explanation:
Probability is given by number of possible outcomes ÷ number of total outcomes
Number of possible outcomes = 270, number of total outcomes = 1200
Probability (the number of people from the suburbs attending the concert is 270) = 270/1200 = 9/40
Probability (the number of people from the suburbs attending the concert is fewer than 270) means that the number of people from the suburbs attending the concert is not 270 = 1 - 9/40 = (40-9)/9 = 31/40
Answer:
5x = (-2)
Step-by-step explanation:
x + y - 6x = y + 2
x - 6x = 2
-5x = 2
5x = (-2)
Answer:
About 3.18
Step-by-step explanation:
If u do the opposite of multiplication u get x
Probability is equal to the favorable outcome divided by the total outcomes. So, in this case, the favorable outcome is blue, which is 8. The total amount of outcomes is 14.
8/14 reduces to 4/7, which is the answer to the first part.
Now you have a total of 18 coins in the bag, because you added three and subtracted one. The favorable outcome is now red, and there were six originally. Adding the three, you now have 9.
9/18 reduces to 1/2, which is the answer to this part.
After you remove a red, you now have 8 reds in the bag. The total is now 20, because you added three and took away one.
8/12 reduces to 2/3, which is your final answer.
Good luck, and I hope my answer was helpful!
