Select all the statements that would be true in a probability model for rolling a cube with faces numbered 1 through 6.

Sample space: 1, 2, 3, 4, 5, 6

P(1) = 16

P(2) = 26

P(6) = 16

The outcomes of the trial: 2, 2, 2, 5, 3, 2, 6, 5, 6, 1

Answers

Answer: A,B, D and E.

Step-by-step explanation:

When a cube with faces numbered 1 through 6 is rolled:

(A)The sample space is 1,2,3,4,5,6. Option A is correct

(B) P(rolling a 1) =1/6, Option B is correct

(C)P(rolling a 2)=1/6, therefore option C is incorrect.

(D)P(rolling a 6)=1/6, Option D is correct

(E)In an experimental trial, the outcome must be members of the sample space. Therefore, the outcomes in option (E), 2, 2, 2, 5, 3, 2, 6, 5, 6, 1 are valid.

Answer:

a) 4x+6

b) 28

Step-by-step explanation:

The perimeter is equal to 1+x+1+x+1+1+1+x+1+x.

Simplifying we have 4x+6.

If we plug in 5.5 for x, we get 4*5.5+6=28

Ten rabbits are put in an enclosed wildlife ranch and the rabbit population triples each year, as shown in the table.

Year Rabbit Population
0 10
1 30
2 90
3 270
4 810
5 2,430
Complete each of the 2 activities for this Task.
Activity 1 of 2
Write an equation where y represents the number of rabbits in x years.

Activity 2 of 2
A second population of 10 rabbits is placed in a second enclosed wildlife ranch and doubles each year.

Select all statements that are TRUE when comparing the equation of the second group of rabbits to the first group.

A.
The base of the exponent will change from 3 to 2.

B.
The function will become quadratic.

C.
The y-intercept will change.

D.
The second population will increase less rapidly.

Answers

Answer:

Step-by-step explanation:

First, we have to find the equation that will give the rabbit population as a function of time and the initial population.

The equation we need turns out to be Population = a0 x 3y where a0 is the initial population and y is the number of years,

To find the rabbit population when a0 = 30 and y =3, use the equation to get Population = 30 x 33 = 810.

You can now find the difference in the number of rabbits at year 3 for the different starting populations.

What sequence of transformations, when applied to △ABC , shows that △ABC is similar to △ A ′ B ′ C ′ ? dilation with respect to the origin by a scale factor of 2 followed by a translation of 2 units left dilation with respect to the origin by a scale factor of 1 2 followed by a translation of 2 units right translation of 2 units right followed by a dilation with respect to the origin by a scale factor of 1 2 translation of 2 units left followed by a dilation with respect to the origin by a scale factor of 1 2

Answers

Answer:

The correct sequence of transformations that shows that △ABC is similar to △A′B′C′ is:

translation of 2 units left followed by a dilation with respect to the origin by a scale factor of 12.

Step-by-step explanation:

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object.

In this case, we can see that a dilation with respect to the origin by a scale factor of 12 would stretch or shrink the triangle, but would not change the angles.

Therefore, we need to apply a translation first to move the triangle into the correct position.

So, we first translate the triangle 2 units left, which does not change its shape or size, but moves it to a position where it can be more easily compared to the other triangle.

Then, we apply a dilation with respect to the origin by a scale factor of 12, which stretches or shrinks the triangle but does not change its shape.

A cone has a height of 10 yards and a diameter of 8 yards. What is the volume?

Answers

Answer: 167.55 units cubed

Step-by-step explanation:

To find this, you must know the formula for a cone. The area is A=πr(r+h2+r2). We can get that the A=π4(4+102+(4)2). We got this from plugging in the numbers. The radius is equal to half the diameter, so the radius is 4. The answer is 167.55 units cubed.

Latasha deposits 250$ into a account savings. The simple intrest rate paid is 3.5%. how much interest does Latasha earn in one year?

Answers

Multiply $250 by 3.5% = 8.75
250 + 8.75 = 258.75

The amount of interest that Latasha earns in one year will be $8.75.

What is simple interest?

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

The formula for interest is written as,

I = (PRT)/100

Where P is the principal, R is the rate of interest, and T is the time.

Latasha deposits $250 into her account savings. The simple interest rate paid is 3.5%.

Then the amount of interest that Latasha earns in one year will be given as,

I = ($250 x 3.5 x 1) / 100

I = $875 / 100

I = $8.75

The amount of interest that Latasha earns in one year will be $8.75.

Eight hundred years ago a powerful king named Genghis Khan ruled an empire that stretched from eastern Europe to the Sea of Japan and included all of China. His armies marched on China and Persia, and Khan was known as the greatest king since Alexander the Great.B According to legend, one day Khan gathered some friends and servants and rode into the countryside to search for game. Everyone in the party had high hopes of bringing home enough meat for a great feast that night. In those days it was customary to bring a trained hawk along on hunting trips. On command, the hawk would leave its masters wrist and fly high into the sky. Then, using its exceptional eyesight, the hawk would spot its prey and swoop down on it, so the hunters would know where to follow.C On this trip the king had brought his favorite hawk. It was a hot summer day, and although the hunting party rode for hours, they had no luck finding game. At dusk they gave up and turned toward home. The king knew the area well, and while the hunting party took the fastest way home, the king rode off on his own between two large mountains, determined to have a successful hunt. In the valley, his hawk flew off.D As the king rode farther, he became parched and started looking for a spring of water. His thirst was growing, but the hot summer had dried up all the brooks that usually ran by the path. Finally, he spotted a trickle of water running over the edge of a steep rock. Quickly, he jumped from his horse, taking a small silver cup from his bag. He held the cup under the trickle of water until there was enough to drink.E However, as he raised the cup to his lips, there was a whooshing sound, and the cup was knocked from his hand to the ground. The king turned to see who could be responsible. Spotting his pet hawk, he wondered why the bird would do such a thing. Angrily, the king picked up the cup and again held it under the trickling water. This time he held the cup for just a few seconds before he began to raise it to his mouth. Just as the cup touched his lips, the hawk flew down again, rushed past the king, and again knocked the cup to the ground.F The king was very angry now. Again he filled the cup, and again the hawk kept him from having even the smallest drink. You awful bird! the king shouted. If you were near me I would kill you in an instant! As the king filled the cup for the fourth time, he spoke to the hawk. Now, you arrogant hawk, I warn you. If you value your life, let me drink. As he spoke, he held his sword ready. Again the bird flew down, knocking the cup from the kings hand; but this time, the king was ready. His sword flashed and the bird fell. The hawk dropped at his masters feet and died quickly.G That will teach you, said the king. Then Genghis Khan turned and looked for the cup, but it was nowhere to be found. I will drink now anyway, he said, and started climbing the steep rock toward the source of the water. It was a long climb, and the kings thirst grew and grew.H Finally, he reached the top and could see the water. As he walked closer, he could see something in the water. With one more step the king could see now that the huge thing was a dead snake, one of the most poisonous in his entire kingdom.I Now, the king stopped walking. He forgot his thirst, and his heart ached as he thought dismally of the dead hawk he had left lying on the ground below. He dropped his head and said, You were a true friend, Sir Hawk. You saved my life, and yet in anger I killed you. I will honor your memory and never forget the lesson you taught me.In paragraph A, the author most likely compares the king with Alexander the Great inorder to show that the kingA. was enormously powerfulB. hoped to become famousC. came from noble blood linesD. was humble despite his high position What is the area of khaptad lake Here is to gone as smile is to HELP PLEASE!!
