What is the value of p?
asambeis [7]

Answer:94°

Step-by-step explanation:

The sum of the interior angles of the polygon: 180°(n-2)

180°(5-2)=540°

The sum of the interior angles of the pentagon is 540°

So:

P+Q+R+S+T=540°

(4x+2)°+132°+(4x-10)°+(5x-11)°+128°=540°

4x+2+4x-10+5x-11+260=540

13x=299

x=23°

P=4x+2°=4×23°+2°=94°

jekas [21]

Answer: The required expected value is $3.46.

Step-by-step explanation:

Since we have given that

Number of value of 4 or less are

2,3,4

So, there are 12 in numbers.

So, probability would be

\dfrac{12}{52}

Since Aces are considered as the highest card in the deck.

So, remaining probability would be

\dfrac{40}{12}

Amount paid or value of 4 or less = $165

Amount not paid for other case = $45

So, the expected value would be

\dfrac{12}{52}\times 165-\dfrac{40}{52}\times 45\\\\=\dfrac{1980}{52}-\dfrac{1800}{52}\\\\=\dfrac{180}{52}\\\\=3.46

Hence, the required expected value is $3.46.
