Answer:

  • 103°

Step-by-step explanation:

  • <em>This is a cyclic quadrilateral (all vertices on the same circle)</em>

<u>Opposite angles are supplementary:</u>

  • ∠A +  ∠C = 180°
  • ∠B +  ∠D = 180°

<u>Find x:</u>

  • x + 5 + x - 7 = 180°
  • 2x - 2 = 180°
  • 2x = 182°
  • x = 91°

<u>Find D:</u>

  • ∠D = x - 14°
  • ∠D = 91° - 14° = 77°

<u>Find B:</u>

  • ∠B = 180° - 77° = 103°

On a Sunday night, there are four people on a bus. The bus has five stops left before it end sits route. Suppose each person wil
allochka39001 [22]

There are two possible outcomes of this experiment either success p or failure q. It has a given number of trials and all trials are independent therefore it is<u><em> binomial probability distribution.</em></u>

1-  5 ways

2- 5/16

3- 1/16

4- 1/16

In the question given above n= 5 p =1/2 q= 1/2  r is the given point.

  1. <u>Part 1:</u>

The number of ways in which different people get off the bus can be calculated using combinations since the order is not essential. Therefore

nCr= 5C4= 5 ways

<u>2. Part 2:</u>

The probability that all four people get off the bus on the first stop is given by :

P (x= 1)= 5C1 (1/2)^0(1/2)^4= 5(1/2)^4= 5/16

<u>3. Part 3:-</u> The probability that all four people get off the bus on the same stop.

P (x= x)= 5C5 (1/2)^0(1/2)^4= 1(1/2)^4= 1/16

<u>4. Part 4-</u> The probability that <u><em>exactly three of the four</em></u> people get off the bus on the same stop.

P (x= x)= 5C5 (1/2)^3(1/2)^1= 1(1/2)^4= 1/16
