Answer:0.017578

Step-by-step explanation:

Given

Nine coins are flipped

So the probability of getting a tail is \frac{1}{2}

Because on flipping a coin could either yield Head or tail

so getting a tail on nine trails is \frac{1}{2^9}

but this tail can come on first coin or second or third ....

So there are 9 possible ways

So probability of getting a tail on flipping nine coin is 9\times \frac{1}{2^9}

=\frac{9}{2^9}=0.017578

Answer:

70

Step-by-step explanation:

The angle not marked in the top triangle is 40 degrees since it is an isosceles triangle.  That makes the angle opposite it in the other triangle 40 degrees since they are vertical angles and vertical angles are equal.

The bottom triangle has 3 angles that sum to 180 degrees,  The other angle not marked is also y since it is an isosceles triangle.

40 + y +y = 180

Subtract 40 from each side and combine like terms

40-40 +2y = 180-40

2y = 140

Divide by 2

2y/2 = 140/2

y = 70
