A pair of coins is tossed. What is the probability of no tails? <br> 0 <br> 1/2 <br> 1/4
lesya [120]
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.

If you were to randomly survey 20 people at 50 randomly chosen high schools, would this be a random sample? Why or why not?
prisoha [69]

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.

The table shows the number of tickets each team sold. If they sold the same, how many did each sell? Remember to continue beyond
BartSMP [9]

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.

Haley has 48 colored pencils and 3 cups (A, B, C). Cup A holds one more colored pencil than cup C. Cup B holds 2 more colored pe
Marina86 [1]

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 :)
