The expectation to play the game is $2.5 and the fair price to play is $7.5.

The expectation is defined as the weighted average value of the random variable which is the product of the value of the random variable and its possibility.

Expectation= ∑P(win)*amount of win or loss of random variable

=∑x*P(x)

Here given that there are only two possible outcomes $5 and $10. And the possibility of every outcome is the same which is 0.5 as they occupy the same area.

As we know

Expectation= ∑P(win)*amount of win or loss of random variable

= 0.5(5-5) +0.5(10-5)

=0.5*0 + 0.5*5

=0+2.5

=$2.5

As fair price= expectation + cost of play

⇒fair price= $2.5 + $5

⇒fair price= $7.5

Therefore the expectation to play the game is $2.5 and the fair price to play is $7.5.

Step-by-step explanation:

First, you start by simplifying the fractions. 40/12 = 3 4/12 = 3 1/3, therefore A is correct. 35/4 = 8 3/4,  therefore B is correct. 23/6 = 3 4/6 = 3 2/3. The two fractions aren't equal so C is incorrect. 15/8 = 1 7/8, both fractions are the same so D is correct. 11/4 = 2 3/4, the fractions are not equal so option E is incorrect.

To determine the total cost of the game, we can set up an equation based on the given information.

Let's assume the total cost of the game is represented by the variable "x."

According to the problem, Tom has saved $18, which is two-thirds of the total cost. We can express this as the equation:

(2/3) * x = $18

To solve for x, we can multiply both sides of the equation by the reciprocal of 2/3, which is 3/2:

(3/2) * (2/3) * x = (3/2) * $18

x = $27

Therefore, the game costs $27.

Answer:A two-step equation is an algebraic equation you can solve in two steps. Once you've solved it, you've found the value of the variable that makes the equation true. Example 1 We're given an equation and asked to solve for x x: 3 x + 2 = 14 3x + 2 = 14 We need to manipulate the equation to get x x by itself.

Answer:

(1.3^9)/(1.3^3)= Last Column: (1.3)^6

(-5/6)^2= First Column: -5^2/6^2

(-5/6)^1: Third Column: -5/6

(1.3)^0: Second Column: 1

Answer:

first row last column, second row first column, third row third column, last row second column

Step-by-step explanation:

first row last column: doing division w/ exponents means you have to subtract the exponents. 9-3=6 and since they have the same base, you don't have to do anything with it, so the answer is the last column.

second row first column: properties show that the square of -5/6 is equal to -5^2/6^2 or 5^2/-6^2. therefore, the answer is the first column.

third row third column: anything to the power of one is itself.

last row second column: anything to the power of zero is one.

Hello there!

First things first, place the 2 on the y-axis. 2 is your "y" intercept.

Rule of thumb:  if there is a constant(single number) alone and without any variable next to it, it's going to be your y-intercept.

Next we need to count up three units from the y-intercept and over four units.

Overall:

The 2 should be plotted on the y-axis.

The new coordinate should be (5,4)

Step-by-step explanation:

Answer:

Jon is 10 years old

Step-by-step explanation:

This is solved using linear equations. We use the information given to make equations.

Let's use K for Kylie, E for Ellie, and J for Jon:

K = E + 5

K = J x 3

Now, we rearrange these equations so that K is on the right side:

E = K - 5

J = K/3

Now, with only one variable, we make a new equation:

K + (K - 5) +  (K/3) = 65

Simplify:

2K - 5 + K/3 = 65

Isolate k:

\(\frac{7k}{3}-15=65(3) = 195\\7k=196+15=210\\k = \frac{210}{7}=30\)

Now we can plug K in to find Jon's age:

J = K/3

J = 30/3

J = 10

If Kylie is 5 years older than Ellie and triple Jon's age. If the sum of their ages is 65 then Jon is 12 years old.

Let's assume Jon's age is "J" years.

According to the given information:

1. Kylie is 5 years older than Ellie, so Ellie's age is "J + 5" years.

2. Kylie's age is triple Jon's age, so Kylie's age is "3J" years.

The sum of their ages is 65, so we can set up the equation:

J + (J + 5) + 3J = 65

Now, combine like terms:

5J + 5 = 65

Next, isolate "5J" by subtracting 5 from both sides of the equation:

5J = 65 - 5

5J = 60

Now, divide both sides by 5 to find the value of "J":

J = 60 / 5

J = 12

So, Jon is 12 years old.
