**Answer:**

For many(n) tickets, the average payoff is 0.5n, in which n is the number of tickets.

**Step-by-step explanation:**

**1/1000 chance of winning.**

This means that there is an 1/1000 probability of you earning $500.

**1 - 1/1000 = 999/1000 chance of losing.**

In this case, you earn nothing.

**What is your average payoff from many tickets**

[tex]A = \frac{500*1}{1000} + \frac{0*999}{1000} = \frac{500}{1000} = 0.5[/tex]

Your average payoff from a ticket is 0.5. So for many(n) tickets, the average payoff is 0.5n, in which n is the number of tickets.

can't quite figure out the limit problem

Use the squeeze theorem; if

1 - *x* ²/4 ≤ *u(x)* ≤ 1 + *x* ²/2,

then taking the limit on each part as *x* approaches 0 gives

1 ≤ lim [*x* → 0] *u(x)* ≤ 1

and so the limit of *u(x)* as *x* → 0 is simply **1**.

**Answer:**

(0, 1) and (4, 7)

**Step-by-step explanation:**

We are going to find the equation that satisfy the question.

The equation of a line is: [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept.

The problem gives us the slope and a point the line passes through.

In order to find b, we plug in the given point (2,4) and solve.

[tex]4=\frac{3}{2} *2+b[/tex]

[tex]4=3+b\\1=b\\[/tex]

The equation for the line is:

[tex]y=\frac{3}{2} x+1[/tex]

By plugging in the points to see if it is true, we get that only (0,1) and (4,7) are on the line.

Consider the cylinder with a volume of 132 cm3.

What is the volume of a cone with the same radius and

height as the cylinder?

O 337 cm

O 447 cm

O 66 cm

O 132 cm

3

V = 132 cm

HELPPP

**Answer:**

447 cm or 337 cm can be both

The volume of the **cone** whose height and **radius **are equal to that of given **cylinder`s** height and radius is equal to 44cm³.

The volume of given **cylinder** is = 132cm³

The volume of a cylinder of radius r and height h is given by

V=πr²h

Therefore, πr²h=132

Now volume of **cone** of same radius and height is = (1/3)πr²h

=(1/3)×132

=44cm³

Hence, the volume of the **cone** with same radius and height as of given **cylinder** is 44cm³.

Eliminate the parameter. x = t^2 + 1, y = t^2 - 1.

**Answer:**

Eliminating the parameter, the equation is [tex]y = x - 2[/tex]

**Step-by-step explanation:**

**We are given the following parametric equations:**

[tex]x = t^2 + 1[/tex]

[tex]y = t^2 - 1[/tex]

We want to eliminate the parameter t. From the first equation:

[tex]x = t^2 + 1[/tex]

[tex]t^2 = x - 1[/tex]

**Replacing in the second equation:**

[tex]y = x - 1 - 1[/tex]

[tex]y = x - 2[/tex]

Eliminating the parameter, the equation is [tex]y = x - 2[/tex]

Solve x2 – 2x = 15 by applying the quadratic formula.

Using the** quadratic formula, **the value of x in the given situation is x = 4 ± √2+60x/2x.

The quadratic formula in elementary **algebra **is a formula that yields the answer to a quadratic problem.

In addition to the quadratic formula, other methods of solving quadratic equations include factoring, completing the square, **graphing**, and others.

A second-order equation of the form ax² + bx + c = 0 denotes a quadratic equation, where a, b, and c are real number coefficients and a 0.

We have:

x² – 2x = 15

x² – 2x - 15 = 0

The formula is:

x = -b ± √b² - 4ac/2a

Now, insert values as follows:

x = -b ± √b² - 4ac/2a

x = -(-2) ± √(-2)² - 4(x)(-15)/2x

x = 4 ± √2+60x/2x

Therefore, using the** quadratic formula, **the value of x in the given situation is x = 4 ± √2+60x/2x.

Is s=2/3 a solution of 6s−1=3s?

**Answer:**

nope

**Step-by-step explanation:**

No, s=2/3 is not a **solution **of 6s−1 = 3s.

Equations whose variables have a power of one are called **linear equations**. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.

Given:

A **linear **equation,

6s − 1 = 3s.

**Substituting**,

s = 2/3,

**Equation **is,

3 ≠ 2

**Simplifying**,

6s - 3s = 1

3s = 1

s = 1/3

That means, s = 1/3 is the only **solution **of the equation.

Therefore, s = 2/3 is not a solution to the **equation**.

Find the perimeter of the following shape, rounded to the nearest tenth

19.1

Step-by-step explanation:

i took the testttttt

**Perimeter **is the sum of the **length **of the sides used to make** **the given figure. The **perimeter **of the given shape is **19.1 units.**

The **distance **or length of any line on the graph,

[tex]{\rm Distance} = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]

where,

d = distance or **length** of the line between points 1 and 2,

(x₁ , y₁) = **coordinate **of point 1,

(x₂ , y₂) = **coordinate **of point 2,

To find the **perimeter **of the given figure we need to **calculate **the length of each line **segment **on the given graph. Therefore, the **length** of the different **sides **of the given **quadrilateral **can be written as,

AB = √[(5-0)²+(-1-0)²] = √26 units

BC = √[(5-3)²+(-1+5)²] = √20 units

CD = √[(3+2)²+(-5+4)²] = √26 units

AD = √[(-4 - 0)²+(- 2 - 0)²] = √20 units

**Perimeter **= AB + BC + CD + AD

= √26 units + √20 units + √26 units + √20 units

= 19.1423 units ≈ 19.1 units

Hence, the **perimeter **of the given shape is **19.1 units.**
