Answer 1

Given :   Eitan rolls a fair six-sided die and a fair four-sided die simultaneously. A be the event that the sum of the dice is 8 and B be the event that Eitan rolls doubles

To find : probability of event A  , event B  , Event A or B  , Event A & B

Solution:

Six  Sides  Dice has { 1 , 2 , 3 , 4 , 5 ,6  }

4 Sides Dice has  = {  1 , 2 , 3 ,  4 }

Total possible outcome = 6 * 4  = 24

n(S) = 24

A  = Sum of Dice  = 8

(4 , 4)  , ( 5 , 3) , ( 6 , 2)

n(A) = 3

B  =   Double  ( means same number on each Dice )

B = ( 1 , 1) , (  2, 2) , ( 3 , 3) , ( 4, 4)

n(B) = 4

A U B  = ( 1 , 1) , (  2, 2) , ( 3 , 3) , ( 4, 4) ( 5 , 3) , ( 6 , 2)

n (A U B )   =  { 6 }

A ∩ B = { 4 , 4}

n(A ∩ B)  = 1

Probability of Event A  =  3/24  = 1/8

probability of Event B = 4/24   = 1/6

Probability of Event A or B  = 6/24  = 1/4

Probability of Event  A and B = 1/24

Determine whether [3x + 12 + x] is equivalent to [4(3 + x)]. Use properties of operations to justify your answer.

Answers

Answer:

3x + 12 + x = 4x + 12 becuase 3x and x are like terms so you can add them

4(3 + x) = 12 + 4x because 4 times 3 is 12 and 4 times x is 4x so you add them to get 12 + 4x which can be rearranged to equal 4x + 12

So in short: 3x + 12 +x is equivalent to 4(3+x)

So our equation currently is ⇒ [tex]x^2+y^2-10x+8y-8 = 0[/tex]

Let's first move all the constant to one side and group 'like variables' together:

      [tex](x^2-10x)+(y^2+8y) = 8[/tex]

Now lets complete the square of both equations

    [tex](x^2-10x+25)+(y^2+8y +16) = 8 + 25 + 16\\(x-5)^2+(y+4)^2 = 49\\(x-5)^2+(y+4)^2 = 7^2[/tex]

Now we know the circle's general equation format is:

   ⇒[tex](x-h)^2+(y-k)^2 = r^2[/tex]

(h, k) ⇒ coordinate of the center of the circler ⇒ length of radius of circle

Thus the radius of the circle is 7

d) You have a difference of squares:

Recall the identity,

a² - b² = (a - b) (a + b)

So,

e) Pull out the common factor 3 from each term:

3x² - 3x - 90 = 3 (x² - x - 30)

Now use the sum-product method. Notice that we can write 30 = 5 • 6, and 5 - 6 = 1, so

In an RPG game, each player can choose among 5 basic classes: Mage, Warrior, Archers, Priests, Monks. Each basic class can advance to 4 sub-classes. If each character can have two sub-classes at the same time, how many different combinations are there?

Answers

Answer:

In RPGs a Character Class is a designation that determines a player's abilities and fighting style (and depending on the game possibly even their origin, education, and home area) often in the form of a job or archetype. A character class is defined by the abilities that it lends to a character — as such, two different characters with the same class are theoretically interchangeable, in that they have the same "power set" and can play the same role in gameplay because of their similar abilities. However, character class systems can come with varying levels of customization — ranging from characters of a given class being literally identical to having so much variety that character class is no longer even a good indicator of that character's abilities. While most common in fantasy Role-Playing Games, they have recently began to appear in other genres, such as trading card games and MOBAs.

answer:288
since it’s a cube , all side lengths will be equal- in this case , 6 feet.
to get the area of one wall , you do height x width- in this case 6x6.
that equals 36 , which is the area for 1 wall.
since they’re painting all 8 walls , you multiply 36x8
that gets you the answer 288 (feet squared)

What is the volume of a right triangular prism?

A right triangular prism is a 3-dimensional triangle with two congruent triangular faces and 3 rectangular faces that connect the triangular.

The volume of a right triangular prism = ( height × Base Area)

A. The length of the tent to the nearest foot, from the front to the back

= 15 + 6 + 15+ 6

= 42 ft

B. Given that the tent is in the shape of a triangular prism the volume of the prism will be given by:

The volume of a right triangular prism = ( height × Base Area)

                           

height = √(36 - 9)

In fact, all domestic dogs are descended from wolves. There are several species of wolf, including the gray wolf, the arctic wolf, the red wolf, the white wolf, and the Mexican wolf. Wolves are some of the most widespread mammals. Populations of wolves exist in almost as many places around the globe as humans do.Wolves are exceptional pack hunters. This is why they are able to take down large prey such as moose or deer by working together as a seamless team. Wolf pups as young as eight months old begin helping on the hunt. Wolves can reach speeds of up to 40 miles per hour when chasing prey, and their thick, double-coated fur enables them to keep warm in even the coldest arctic temperatures. Their large, powerful paws can reach up to 5 inches across and help to propel them quickly across the snow.Next time you're playing fetch with your furry friend, think about its ancestor, the wolf. That terrier or pug might only be able to take down a ball or a bone, but it gained its instincts to chase and hunt from those greatest of hunters, the wolves.Read the article "The Necessity of Hybrids".What do you get if you cross two different species? Depending upon the species, you might end up with a grolar bear, a wolfdog, or a Savannah cat, among many others. What do these animals have in common? They're hybrids. Sometimes hybrids happen naturally in the wild, but usually, hybrids are the result of humans selectively breeding animals.Grolar bears and pizzlies are the result of crossing polar bears and grizzly bears. These hybrids were first seen in zoos, as the bears' natural habitats did not normally overlap. Recently, these hybrids have started appearing in the wild. Due to climate change, the bears' once-separate habitats are beginning to overlap. Bigger and more aggressive than their parents, grolar bears and pizzlies could pose a risk to natural habitats and humans.Wolfdogs are, as their name suggests, the result of crossing a wolf with a domestic dog. Bred for the pet trade, these hybrids do not often happen in the wild. Wolfdogs do not make good pets, however, as they can be destructive and aggressive. Many states have outlawed keeping wolfdogs because they can pose a danger to people.Savannah cats are another example of human-made hybrids that were developed to be pets. Savannahs are the result of crossing a small wildcat called a serval with a domestic housecat. They look like miniature versions of the wildcat, which is why many people like keeping them as pets. Like the wolfdog, however, Savannahs do not make ideal house pets. They can be destructive, and usually, they keep the wild nature of the serval.There are many more examples of human-made hybrid animals. Some hybrids, such as the mule, have been helpful to humans. Unfortunately, others, like the wolfdog or Savannah cat, should not have been made in the first place.How is the overall structure of "The Wolves Among Us" similar to the structure of "The Necessity of Hybrids"?
