Answer:

\overset{\frown}{WX}= 66^{\circ}

Step-by-step explanation:

<u>Inscribed Angle Theorem</u>

The measure of an <u>inscribed angle</u> is half the measure of the <u>intercepted arc</u>.

First, use the Inscribed Angle Theorem to calculate the measure of arc WY.

  \displaystyle \angle WXY=\dfrac{1}{2} \overset{\frown}{WY}

\implies 57^{\circ}=\dfrac{1}{2} \overset{\frown}{WY}

\implies \overset{\frown}{WY}= 2 \cdot 57^{\circ}

\implies \overset{\frown}{WY}= 114^{\circ}

Assuming XY is the diameter of the circle:

\implies \overset{\frown}{WY}+ \overset{\frown}{WX}= 180^{\circ}

\implies 114^{\circ} + \overset{\frown}{WX}= 180^{\circ}

\implies \overset{\frown}{WX}= 180^{\circ} - 114^{\circ}

\implies \overset{\frown}{WX}= 66^{\circ}

In an experiment, a fair coin is tossed 13 times and the face that appears (H for head or T for tail) for each toss is recorded.
zalisa [80]

Answer:

1) 1 element

2) 13 elements

3) 22 elements

4) 40 elements

Step-by-step explanation:

1) Only one element will have no tails: the event that all the coins are heads.

2) 13 elements will have exactly one tile. Basically you have one element in each position that you can put a tail in.

3) There are {13 \choose 2} = 78 elements that have exactly 2 tails. From those elements we have to remove the only element that starts and ends with a tail and in the middle it has heads only and the elements that starts and ends with a head and in the 11 remaining coins there are exactly 2 tails. For the last case, there are {11 \choose 2} = 55 possibilities, thus, the total amount of elements with one tile in the border and another one in the middle is 78-55-1 = 22

4) We can have:

  • A pair at the start/end and another tail in the middle (this includes a triple at the start/end)
  • One tail at the start/end and a pair in the middle (with heads next to the tail at the start/end)

For the first possibility there are 2 * 11 = 22 possibilities (first decide if the pair starts or ends and then select the remaining tail)

For the second possibility, we have 2*9 = 18 possibilities (first, select if there is a tail at the end or at the start, then put a head next to it and on the other extreme, for the remaining 10 coins, there are 9 possibilities to select 2 cosecutive ones to be tails).

This gives us a total of 18+22 = 40 possibilities.
