A game involves drawing a single card from a standard deck. One receives 60 cents for an ace, 30 cents for a king, and 5 cents for a red card that is neither an ace nor a king. If the cost of each draw is 10 cents, what is the expected value?
Answer:
The expected game value is -1 cent
Step-by-step explanation:
Here, we want to calculate the expected value of the game
We have 4 aces and 4 kings, including 26 red cards
The number of aces is 4
Probability of drawing an ace is 4/52 = 1/13
Probability of drawing a king is also 4/52 = 1/13
There are 26 red cards
The number of red cards that are neither ace nor king
There are 2 red aces and 2 red kings
So the number of cards that are red but are not
aces nor kings are 26-2-2 = 22
The probability of selecting this is 22/52 = 11/26
So the expected value is simply the probability multiplied by the amount
Thus, we have;
(60 * 1/13) + (30 * 1/13) + (5 * 11/26)
= 60/13 + 30/13 + 55/26
= (120 + 60 + 55)/26 = 9.038 cents which is approximately 9 cents
we subtract this from the 10 cents we are playing with, thus we are left with 9-10 = -1 cent

Answer:
-3y + 2x - 4
Step-by-step explanation:
Answer:
-3y - 4 + 2x
Step-by-step explanation:
when it says combine like terms, it means combine the terms that have the same variable
-7y, -2y, and 6y all have the same variable: y
so when you combine them, you get -3y (notice that the variable doesn't change, only the number in front of it does)
-2 and -2 are like terms, they don't have a variable
when you combine them, you get -4
-4x and 6x are like terms, their common variable is x
when you combine these, you get 2x
now put your answers together to get -3y - 4 + 2x

11/5, 11/8, 17/15, 17/20.
Answer:
11/15
Step-by-step explanation:
17/8 is to 17/20 as 11/6 is to x.
(17/8) / (17/20) = (11/6) / x
(17/8)x = 17/20 * 11/6
(17/8)x = 187/120
(8/17) * (17/8)x = 8/17 * 187/120
x = 11/15
Answer:
11/15

Sara hired her brother James to help her sell
lemonade. Sara agreed to pay James $1.00, plus
$0.10 for each glass of lemonade that he sold.
Sara paid James $3.60. How many glasses of
lemonade did James sell?
Answer:
3 Lemonade
Step-by-step explanation:
We add $1.00 with $0.10, then we get $1.10
We then divide $1.10 to the amount Sara paid
$3.60/1.10, we will get the answer 3

The equations of the line that passes throught the point given in the table are as follows;
[tex]y = -\frac{1}{6} x+\frac{1}{3}[/tex]
[tex]y-2=-\frac{1}{6}(x+10)[/tex]
Equation of a straight lineThe linear equation of a striaght line is represented as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore,
m = 1 - 2 / -4 + 10
m = - 1 / 6
Let's find b using (-10, 2)
2 = - 1 / 6(-10) + b
2 = 5 / 3 + b
b = 2 - 5 / 3
b = 6 - 5 / 3
b = 1 / 3
hence,
[tex]y = -\frac{1}{6} x+\frac{1}{3}[/tex]
using y - y₁ = m(x - x₁)
y₁ = 2
x₁ = -10
m = - 1 / 6
Hence,
[tex]y-2=-\frac{1}{6}(x+10)[/tex]

Answer:
Please check the explanation.
Step-by-step explanation:
Given the right angled-triangle ABC as shown in the attached diagram
From the triangle:
Ф= ∠C = 30°
AB = 6 units
BC = y
tan Ф = opp ÷ adjacent
The opposite of ∠C = 30° is the length '6'.
The adjacent of ∠C = 30° is the length 'y'.
As Ф= ∠C = 30°
so
tan Ф = opp ÷ adjacent
tan 30 = 5 ÷ y
1 ÷ √3 = 5 ÷ y
y = 8.7 units
Therefore, the length of the unknown side length 'y' is 8.7 units.

The answer is, sin (2x)=4√21/25
What is trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Here, given that,
sin(x)=2/5
and tan(x)>0
Then, cos(x)=√21/25
tan(x)=2/√21
Now, sin (2x)=2tan(x)/1+tan²(x)
