Out of 3 coins, if you are given that 1 is on tails, then the most heads you could have is 3 coins - 1 tails = 2 heads.
The probability of getting 3 heads would be 0.
Answer: x = 11
Step-by-step explanation:
Complementary angles = 90*
Set the two equations equal to 90. Solve
4x + 6 + 4x - 4 = 90
8x +2 = 90
8x = 88
x = 11
Plug it in to see if it makes equation true
4 (11) + 6 + 4 (11) - 4 = 90
44 + 6 + 44 - 4 = 90
50 + 40 = 90
90 = 90
Mean = (19 +27 +25+21+44+22+45+34)/8 = 29.625≈30 years
Answer is 30.
Answer:
14.95
Step-by-step explanation:
every 1 pound is 2.99 so you would do 2.99 * 5
It would be D because you need to multiply 38 and 50. But x is the length of one classroom, and because we don't know it, you would get 38(50-x).
Good luck!!
