Answer:
$27.41
Step-by-step explanation:
Meal Cost = $86.50
Sales Tax= 6.75% of the Meal Cost
= 6.75% X 86.50
= 0.0675 X 86.50
=$5.84
They tipped the Waiter 20%
20% of 86.50
=0.2 X 86.50
=$17.30
Total Bill= Meal Cost + Sales Tax + Tip
= 86.50 +5.84 + 17.30
=$109.64
Since the friends are four, each one will be expected to pay:
$109.64/4
=$27.41
Each of the friends should pay $27.41 to the nearest cent.
Step-by-step explanation:
4300$ - 100%
x$ - 8%
(4300 × 8) ÷ 100 = 344$
344 + 320 = 664$
answer: 664$ :))))
Complete question :
Suppose someone gives you 8 to 2 odds that you cannot roll two even numbers with the roll of two fair dice. This means you win $8 if you succeed and you lose $2 if you fail. What is the expected value of this game to you? What can you expect if you play 100 times.
Answer:
$0.5 ; win $50 with 100 rolls
Step-by-step explanation:
From a roll of two fair dice; probability of obtaining an even number :
Even numbers = (2, 4, 6) = 3
P = 3 /6 = 1 /2
For 2 fair dice ; probability of rolling two even numbers : independent event.
1/2 * 1/2 = 1/4
Hence, p(success) = 1/4 ; P(failure) = 1 - 1/4 = 3/4
Probability table
Winning = $8 or loss = - $2
X : ____ 8 ______ - 2
P(x) __ 1/4 ______ 3/4
Expected value : E(x) = ΣX*P(x)
E(x) = (8 * 1/4) + (-2 * 3/4)
E(x) = 2 - 1.5
E(x) = $0.5
Since expected value is positive, the expect to win
If played 100 times;
Expected value = 100 * $0.5 = $50
There are 16 cups in 1 gallon:
16 x 2.75 = 44 cups
