A con is tossed n times. How many difference sequences of head and tails can you get?
ryzh [129]

Answer:

2^n

Step-by-step explanation:

So whenever you flip a coin, you can see it as 2 nodes branching off of each existing node. so for example when you flip a coin once you're going to have 2 sequences initially H and T, now when you flip a coin again for each of those 2 sequences 2 are going to branch off of that, making the total sequences 4, and the next flip 2 sequences are going to branch off each of the 4 sequences and so on. this can generally be described as: 2^n

I attached an image describing this a bit better but the bottom line is that for each 'end node'/sequence you're going to have 2 branch off of it, thus for each coin flip the number of sequences multiplies by 2

4(2x + 3) = 5x + 3x - 6
Likurg_2 [28]

Answer:

No solution.

Step-by-step explanation:

4\left(2x+3\right)=5x+3x-6\\4\left(2x+3\right)=8x-6\\4\left(2x+3\right)\\(a=4,\:b=2x,\:c=3)\\=4\cdot \:2x+4\cdot \:3\\=8x+4\cdot \:3\\=8x+12\\8x+12=8x-6\\8x+12-12=8x-6-12\\0=-18

If the final answer is 0 and both sides of this equation are unbalanced, that means there will be no solution.

If A = 30° and r = 12, find x. (Round your answer to the nearest whole number.)
Margaret [11]

Answer:

\boxed{12}

Step-by-step explanation:

A = 30° and r = 12

\sin A = \frac{r}{r + x}

\sin 30 = \frac{12}{12 + x}

\frac{1}{2} = \frac{12}{12 + x}

1(12 + x) = 2(12)

12 + x = 24

x = 24 - 12

x = 12

.

Happy to help :)
