0 cannot be the answer. It makes no sense because you can get a probability of getting tails when flipping a coin.
The answer would be 1/2. You have '2' choices (heads or tails) and 1 out of those 2 times would you possibly get tails.
I'm pretty sure this would be because if I'm correct, the surveyors would not have known where and who they were gonna survey before they went. However, this wouldn't show accurate information because you should survey at least 100 people.
Answer:
each sold 60 tickets
Step-by-step explanation:
Apparently, you're supposed to set the expressions equal and solve for t; then find the values of the expressions.
60(t -1) = 20(t +1)
60t -60 = 20t +20 . . . . . eliminate parentheses
40t = 80 . . . . . . . . . . . . . . add 60 -20t
t = 2 . . . . . . . . . . . . . . . . . . divide by 40
__
60(2 - 1) = 60 . . . . . solve for Falcons sales
20(2 + 1) = 60 . . . . .solve for Eagles sales (should be equal; it is)
Each team sold 60 tickets.
Answer:
17 pencils
Step-by-step explanation:
Assume that cup C holds x pencils. In this case, cup A holds x + 1 pencils, and cup B holds x + 2 pencils. We know that all of the cups together hold 48 pencils. If we add what we got together, we would get x + x + 1 + x + 2 = 48. 2x + 1 + x + 2 = 48. 2x + x + 1 + 2 = 48. 3x + 1 + 2 = 48. 3x + 3 = 48. 3x = 48 - 3. 3x = 45. x = 45 / 3. x = 15. Now, we know that cup C holds 15 pencils, and from here, we can find the number of pencils in cup B by adding 2 to 15 and getting 17, and that would be your answer.
Tell me if I'm wrong :)
