Matt decided to go out to eat. He ordered a soda for $2.15, some chicken for $8.77 and a slice of cake for $4.10. What would his
nikklg [1K]

Answer:  $ 17.72

Step-by-step explanation:

Cost of soda = $2.15 , Cost of chicken = $8.77 , Cost of slice of cake = $4.10.

Total bill amount = (Cost of soda ) + (Cost of chicken) +(Cost of slice of cake)

= $ (2.15 + 8.77 +4.10)

= $ 15.02

Tip amount = 18% of Total bill amount

= 0.18 (15.02)

= $ 2.7036 ≈  $2.70

Entire bill = Total bill amount  + Tip amount

= $ ( 15.02+2.70)

= $ 17.72

Hence, entire bill = $ 17.72

You pick a card at random from an ordinary deck of 52 cards. If the card is an ace, you get 9 points; if not, you lose 1 point.
denis-greek [22]

Answer:

Step-by-step explanation:

In a deck of 52 cards there are 4 aces.

Therefore the probability of obtaining an ace is:

P (x) = 4/52

The probability of not getting an ace is:

P ('x) = 1-4 / 52

P ('x) = 48/52

In this problem the number of aces obtained when extracting cards from the deck is a discrete random variable.

For a discrete random variable V, the expected value is defined as:

Where V is the value that the random variable can take and P (V) is the probability that it takes that value.

We have the following equation for the expected value:

In this problem the variable V can take the value V = 9 if an ace of the deck is obtained, with probability of 4/52, and can take the value V = -1 if an ace of the deck is not obtained, with a probability of 48 / 52
