A gambling game at a local carnival is played as follows: each time someone plays the game, he or she pays $3. A fair die is rolled, and if the die has an even roll (e.g. 2, 4, or 6), he or she wins nothing. If it is an odd roll, he or she wins the amount of money (in dollars on the face of the die—e.g. if he or she rolls a 1, he or she wins $1; a 3, he or she wins $3; a 5, he or she wins $5). The random variable [tex]X[/tex] represents the amount he or she wins per play of the game, not including how much he or she pays.
Part 1: Complete the given table.
Part 2: How much can someone expect to win on average per play of the game? Should he or she pay $3 to play this game? Why or why not?
Answers
Using a discrete probability distribution, it is found that:
1. The table is completed at the end of the answer.
2. The expected earnings for a single play of the game are of $1.5. Since $3 is greater than the average earnings, a person should not pay $3 to play this game.
What is the mean of a discrete distribution?The expected value, also called the mean, of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.
For this problem, we have that:
If it is an even roll, the person wins nothing. Out of 6 possible outcomes, 3 are even numbers, hence P(X = 0) = 3/6 = 1/2.If it is an odd roll, the person wins the amount played, hence P(X = 1) = P(X = 3) = P(X = 5) = 1/6.The table completed with these probabilities is given at the end of the answer.
Hence the expected earnings for the game are given as follows:
E(X) = 1/2 x 0 + 1/6 x (1 + 3 + 5) = $1.5.
If a person paid $3, the expected earnings would be of:
1.5 - 3 = -$1.5.
Negative earnings, hence the person should not pay $3 to play this game.

Tricia buys 18 apples for $27. The total cost, c, of the apples is proportional to the number of apples, a, that she buys. How much does one apple cost? Create an equation using c and a to represent the proportional relationship.
Answers
If Tricia buys 18 apples for $27 and the total cost c of the apples is proportional to the number of number of apples a that she buys, then the cost of one apple is $1.5 and the relationship between c and a is c = 1.5a
The cost of 18 apples = $27
Here we have to use unitary method to find the cost of one apple
The cost of one apple = 27/18
= $1.5
Consider the total cost of the apples as c and the number of apples she bought as a
Then the relationship will be
c ∝ a
c = ka
Here the k is the constant that will be the cost of one apple
The cost of one apple = $1.5
Then the relationship will be
c = 1.5a
Hence, if Tricia buys 18 apples for $27 and the total cost c of the apples is proportional to the number of number of apples a that she buys, then the cost of one apple is $1.5 and the relationship between c and a is c = 1.5a

Step-by-step explanation:
Since the two horizontal lines are parallel
angles with measures of 6y and 3y are supplementary angles and add up to 180°
So 6y + 3y = 180
9y = 190
y = 20

2x + 90 = 180
2x = 90°
x = 45
Answer:
x=45 y=20

Define slope intercept form.Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form. Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form. One of the formulas used to get a line's equation is the slope-intercept formula. Y = mx + b is the slope-intercept formula for a line with slope m and y-intercept b. Any point on the line is (x, y) in this case.

Answers
Given:
The length of yarn needed, l=23 1/4 feet.
The length of a yarn bundle, L=11 1/2 feet.
The number of bundles of yarn needed can be calculated as,
[tex]\begin{gathered} n=\frac{l}{L}=\frac{23\text{ }\frac{1}{4}}{11\frac{1}{2}} \\ n=\frac{\frac{23\times4+1}{4}}{\frac{11\times2+1}{2}} \\ n=\frac{\frac{93}{4}}{\frac{23}{2}} \\ n=\frac{93}{4}\times\frac{2}{23} \\ n=\frac{93}{2}\times\frac{1}{23} \\ n=\frac{93}{46} \\ n=2\frac{1}{46} \end{gathered}[/tex]Therefore, 3 bundles is needed by Jenna to make the scarf.
The part of leftover yarn is,
[tex]\begin{gathered} N^{}=3-2\frac{1}{46} \\ =3-(2+\frac{1}{46}) \\ =1-\frac{1}{46} \\ =\frac{46-1}{46} \\ =\frac{45}{46} \end{gathered}[/tex]Hence, 45/46 part of a bundle of yarn will be left.
Now, the length of leftover yarn is,
[tex]\begin{gathered} l^{\prime}=N\times L \\ =\frac{45}{46}\times11\frac{1}{2} \\ =\frac{45}{46}\times\frac{11\times2+1}{2} \\ =\frac{45}{46}\times\frac{23}{2} \\ =\frac{45}{2}\times\frac{1}{2} \\ =\frac{45}{4} \\ =11\frac{1}{4}\text{feet} \end{gathered}[/tex]Therefore, 111/4 feet of yarn will be left.

3(times)x ;
Rewrite: " 7(x + 4) = 8 − 3x ". This is the written expression.

7(x + 4) ;
Note the 'distributive property' of multiplication:

____
So: 7(x + 4) = 7*x + 7*4 = 7x + 28 ;
Now, let's write the entire equation:
7x + 28 = 8 − 3x ;
Let's add 3x , and subtract 8 ; from Each Side of the equation:
7x + 28 + 3x − 8 = 8 + 3x − 8 ;
→ 7x + 3x + 28 − 8 = 8 − 3x + 3x;
to get:
10x + 20 = 0 ;
Now: Subtract 20 from Each Side of the equation:
10x + 20 − 20 = 0 − 20 ;
to get:
10x = -20 ; Now, divide both sides of the equation by 10 ;

The expansion of ( 2x - y⁵)² using algebraic identity, as a polynomial is 4x² - 4xy⁵+ y¹⁰
What are algebraic identities?Algebraic identities are the identities which aids in solving products or powers of algebraic expressions. Most common identities are :
(a+ b)² = a² + 2ab + b²
(a- b)² = a² - 2ab + b²
a² -b² = (a+ b) (a- b), where a and b can be variable or constants or algebraic expressions.
For expanding (2x - y⁵)²
Use identity (a-b)² = a²-2ab+b², let a = 2x and b = y⁵
Then, ( 2x - y⁵)² = (2x)² - 2(2x)( y⁵) + (y⁵)²
⇒ ( 2x - y⁵)² = 4x² - 4xy⁵+ y¹⁰
