Answer:

(n-2)×180=1080

180n -360=1080

180n = 1080+360

180n =1440

dividing by 180

n=8

hence it is a regular polygon with 8 sides .I.e it is an octagon

Step-by-step explanation:

we are given the total interior angles in the polygon and we know that the formula to find the total interior angles of a polygon is (n-2) ×180

where n is the number of sides

Answer:

k=6, k=-1

Step-by-step explanation:

                         \dfrac{k+3}{3}-\dfrac{2}{k-5}=1

\implies \dfrac{(k+3)(k-5)}{3(k-5)}-\dfrac{3 \cdot 2}{3(k-5)}=1

\implies \dfrac{k^2-2k-15-6}{3(k-5)}=1

\implies k^2-2k-21=3k-15

\implies k^2-5k-6=0

\implies (k-6)(k+1)=0

\implies k=6, k=-1

1. A game is set up as follows: All the diamonds are removed from a deck of cards, and these 13 cards are placed in a bag. The c
Maurinko [17]

Answer:

the game must be played in groups of 13 draws, with a cost of $28 for the 13 draws.

Step-by-step explanation:

Probability of drawing any of the 13 balls is the same. So the expected value of play is the average of the values of each card.

The only losing card is the ace; the player loses $20 if that card is drawn.

Each of the 3 face cards wins $10; each of the remaining 9 cards wins $2.

So the average value of each draw is

\frac{-20+3\times10+9\times2}{13}

= 28/13

Therefore, on average the player will win $ 28/13.  to be a fair game the player must pay  $28/13 for a game.

that is not possible, unless the game must be played in groups of 13 draws, with a cost of $28 for the 13 draws.
