The requried function represents an absolute value parent function.

A graph is shown,

When we see at the points on the curve,
On x = -10 we have y = 10
simultaneously,
On x = 10 again we have y = 10

Step-by-step explanation:

The total amount of money collected from the ticket sales is:

$5/ticket x 3000 tickets = $15,000

The expected value for a person that buys a ticket can be calculated by adding up the probabilities of winning each prize multiplied by the amount of money for each prize:

E(X) = (1/3000) x $500 + (1/3000) x $250 + (1/3000) x $125 + (1/3000) x $50 - (2996/3000) x $5

Simplifying this expression:

E(X) = $0.1666667 + $0.0833333 + $0.0416667 + $0.0166667 - $4.9833333

E(X) = -$4.65

Therefore, the expected value for a person that buys a ticket is -$4.65, which means that on average, a person can expect to lose $4.65 for every ticket they buy.

Answer: $0.31

Step-by-step explanation:

1/3000 tickets will be worth $500.

1/3000 tickets will be worth $250.

1/3000 tickets will be worth $125.

1/3000 tickets will be worth $50.

The remaining 2996/3000 tickets will be worth $0. (Nobody else wins.)

So (1/3000)x500 + (1/3000)x250 + (1/3000)x125 + (1/3000)x50 + (2996/3000)x0 = $0.31.

Please note: This question asks for expected value. Expected value is a measure of what you should expect to get per game. The payoff of a game is the expected value of the game minus the cost.

The formula for v in terms of T is in the equation T = v/6 + 5 is v = 6T - 30.

Given the formula in the question:

T = v/6 + 5

To make v the subject of the formula T = v/6 + 5, we need to isolate v on one side of the equation.

First, we can subtract 5 from both sides of the equation to get:

T = v/6 + 5

T - 5 = v/6 + 5 - 5

T - 5 = v/6

Next, we can multiply both sides by 6 to eliminate the fraction:

6(T - 5) = 6(v/6)

6(T - 5) = v

Simplifying the right-hand side, we get:

6×T 6×-5 = v

6T - 30 = v

v = 6T - 30

Therefore, v as the subject of the formula is v = 6T - 30.

Logan will pay $18.02 more if he buys the wooden stacking toy instead of the plastic stacking toy.

The cost of the plastic stacking toy is 1/3 the cost of the wooden stacking toy:

Cost of plastic toy = (1/3) x $25.50 = $8.50

If Logan buys the wooden toy, he will pay:

Cost of wooden toy = $25.50

To find the amount of sales tax on either toy, we can multiply the cost of the toy by the tax rate of 6%:

Sales tax = 6% x cost of toy

Sales tax on the wooden toy = 6% x $25.50 = $1.53

Sales tax on the plastic toy = 6% x $8.50 = $0.51

If Logan buys the wooden toy, he will pay an extra:

Total cost difference = Cost of wooden toy - Cost of plastic toy + Sales tax on wooden toy - Sales tax on plastic toy

Total cost difference = ($25.50 - $8.50) + ($1.53 - $0.51)

Total cost difference = $17 + $1.02

A quota is a limit on the number of goods that a country can import or export during a specific time period, while an embargo is an official ban on trade with a particular country or good or service. Unlike a quota, an embargo is much more strict as it completely shuts down the trade, but a quota simply limits the amount of trade.

A quota limits the quantity of a specific product that can be imported, while an embargo prohibits the import or export of a particular product entirely.

The primary similarity between quotas and embargoes is that they both restrict the flow of goods between countries. Both policies are designed to protect domestic industries by limiting foreign competition and promoting local production.

The main difference between quotas and embargoes is the way they achieve their objectives. A quota sets a limit on the quantity of a particular product that can be imported into a country during a specified period. In contrast, an embargo prohibits the import or export of specific goods altogether, typically for political reasons such as national security concerns or human rights violations.

The missing values of the average annual precipitation over a 30-year period for Michigan and Nebraska are:

The average annual precipitations over a 30-year period for Michigan and Nebraska are calculated as follows:

The range of the data is 18.1 inches

Indiana has the greatest average annual precipitation of 41.7 inches

Hence, the smallest value = 41.7 - 18.1

The smallest value = 23.6 inches

From the table, this would be the value of either Michigan or Nebraska.

Also, the mean of the values for Michigan and Nebraska is 28.2 inches.

Let the unknown value be y

Hence; (23.6 + y) / 2 = 28.2

y = 56.4 - 23.6

y = 32.8 inches

Since Michigan has a greater amount of annual precipitation than Nebraska, the average annual precipitation over a 30-year period for Michigan and Nebraska is 32.8 inches and 23.6 inches respectively.

Answer:

A- All of the answers listed

Step-by-step explanation:

Let's consider each choices:-

B- A cone with the same height and radius would have a volume of 96π ft³.

In this case, we are replaced with the cone figure that has diameter of 12 feet and height of 8 feet. We know that the formula of cone's volume is:

[tex]\displaystyle{\dfrac{1}{3}\pi r^2 h}[/tex]

Our radius is half of diameter which is 12/2 = 6 feet. Therefore:

[tex]\displaystyle{V = \dfrac{1}{3}\pi \cdot 6^2 \cdot 8}\\\\\displaystyle{V = \dfrac{1}{3}\pi \cdot 36 \cdot 8}\\\\\displaystyle{V = \pi \cdot 12 \cdot 8}\\\\\displaystyle{V=96\pi \ \: \text{ft}^3}[/tex]

Therefore, the statement B is true.

C- The volume of the cylinder is 288π ft³

Finding the volume of cylinder, the volume's formula is [tex]\displaystyle{V = \pi r^2 h}[/tex]. Substitute known values:

[tex]\displaystyle{V = \pi \cdot 6^2 \cdot 8}\\\\\displaystyle{V = \pi \cdot 36 \cdot 8}\\\\\displaystyle{V=288\pi \ \: \text{ft}^3}[/tex]

Therefore, the statement C is also true.

D- The area of the base is 36π ft²

Finding the base's area, our base of cylinder is a circle shape. Therefore, the area of circle is [tex]\displaystyle{A=\pi r^2}[/tex]. Thus:

[tex]\displaystyle{A=\pi \cdot 36}\\\\\displaystyle{A=36\pi \ \: \text{ft}^2}[/tex]

Hence, the statement D is also true.

Therefore, every statements are true. Hence, All of the answers listed are correct answers.

The function g(x)=3a²-4x-1 given represents the quadratic function family.

A quadratic polynomial in mathematics is a polynomial of degree two in one or more variables. The polynomial function defined by a quadratic polynomial is known as a quadratic function.

Prior to the twentieth century, the distinction between a polynomial and its related polynomial function was hazy, therefore "quadratic polynomial" and "quadratic function" were nearly equivalent.

This is still the case in many elementary courses, where both names are sometimes shortened as "quadratic". A quadratic equation is formed when a quadratic function is equated with zero.

The zeros of the appropriate quadratic function are the solutions of a quadratic equation. A quadratic function may have an infinite number of variables.
