Answer:

1/512

Step-by-step explanation:

The probability is 2 out of 2^10 , because there are only two sequences when  same result (heads or tails) shows twice in a row exactly once in the ten tosses (HTHTHTHTHT and THTHTHTHTH) out of 2^10 possible sequences.

2/2^10 = 2/1024 =1/512

Answer:

1. a = 2

2.  x = 12

3. w = 2

Step-by-step explanation:

1. ok so 2a/5 we would want to separate it to 2/5 and a/5

2/5 x a/5 = 2a/5

next we want to subtract 2/5 from 8/10

8/10 - 2/5 or 8/10 - 4/10 = 4/10

now you have a/5 and 4/10

a/5 = 4/10

now you multiply each side by 5

a/5 x 5 = a

4/10 x 5 = 20/10 or 2

a = 2

2. ok so the x is kinda on it's own for this one but we still wan to get the x and the other numbers on opposite sides

1/16x + 1/4 - 1/4 = 1/16x

1/2 + 1/4 = 3/4

now we do that same last step

1/16x / 1/16 = x

3/4 / 1/16 = 12

x = 12

3. ill do one more and if you need more help just tell me

for this on we have the w on both sides so we have to get the variable(w) and the numbers on opposite sides

2w - 2 + 2 = 2w

1/2w + 7 - 1/2w = 7

2w + 1/2w = 5/2w or 2 1/2w

7 - 2 = 5

now we have to divide each side by 5/12 or 2 1/2

5/2w / 5/2 = w

5 / 5/2 = 2

w = 2

Anne can make 6 headbands 3/5 from meters of cloth. Which expression shows the amount of cloth needed to make 1 headband? What i
Marina CMI [18]

The amount of cloth needed to make 1 headband is 10 meters.

<h3>Unit value</h3>

  • Number of headbands Anne made = 6

  • Total clothes used = 3/5 meters

Cloth needed to make 1 headband = Number of headbands Anne made / Total clothes used

= 6 ÷ 3/5

= 6 × 5/3

= (6 × 5) / 3

= 30/3

= 10 meters

Therefore, the amount of cloth needed to make 1 headband is 10 meters.

1) Reflecting over y=x means (x, y) \longrightarrow (y,x). So, the coordinates of the image are:

V(-3, 0) \longrightarrow V'(0,-3)\\\\W(-1,0) \longrightarrow W'(0, -1)\\\\U(-2,-5) \longrightarrow U'(-5,-2)\\\\X(3,-3) \longrightarrow X'(-3, 3)


2) Rotating 90 degrees counterclockwise about the origin means (x,y) \longrightarrow (-y,x), so the vertices of the image are:

W(0,-1) \longrightarrow W'(1,0)\\\\X(3,-1) \longrightarrow X'(1, 3)\\\\V(0,-3) \longrightarrow V'(3,0)\\\\Y(1, -5) \longrightarrow Y'(5, 1)

3) The vertices of the image are:

C(2,0) \longrightarrow C'(-2, -2)\\\\D(2, 5) \longrightarrow D'(-2, 3)\\\\E(5,4) \longrightarrow E'(1, 2)
