A deck of cards has 52 cards.

There are 4 suits, diamonds, hearts, clubs and spades. Each suit has 13 cards.

What is the probability that I will randomly pick a 2, put it back, then randomly pick a 4?

Answers

Answer: [tex]\frac{1}{9}[/tex]

Step-by-step explanation:

The probability that you get a 2 is [tex]\frac{4}{52}[/tex] and that simplifies into [tex]\frac{1}{3}[/tex]. It is the same probability that you get a 4 because you put the 2 back. [tex]\frac{1}{3}[/tex] x [tex]\frac{1}{3}[/tex] = [tex]\frac{1}{9}[/tex],

So for any designated number 1-6 = (p) = 1/6

Step-by-step explanation:

When there is just one event there will always be 6 possible outcomes for one number, so the number of favorable outcomes will be divided by 6 to get your probability.

A) 2 can occur 1 time. P(2) = 1/6

B) there are 3 even numbers. P(even) = 3/6 = 1/2

C) 4 or 5 are 2 possible outcomes. P(4,5) = 2/6 = 1/3

D) there are 3 odd numbers. P(odd) = 3/6 = 1/2

So for any designated number 1-6 = (p) = 1/6

1-6

The height of statue of liberty is 93 meters.

Step-by-step explanation:

Given : Howard has a scale model of the Statue of Liberty. The model is 15 inches tall. The scale of the model to the actual statue is 1 inch : 6.2 meters.

To find : Which equation can Howard use to determine x, the height in meters, of the Statue of Liberty?

Solution :

The model is 15 inches tall.

The scale of the model to the actual statue is 1 inch : 6.2 meters.

Let  x be the height in meters of the Statue of Liberty.

According to question, required equation is

[tex]\frac{1}{6.2} =\frac{15}{X}[/tex]

Answers

Answer: 240 Miles

Step-by-step explanation:

My answer is correct because, if 1 cm =15 miles and the distance is 16 cm apart, then all we have to do is multiply 16 times 15 (since there are 15 miles in 1 cm and theres 16 cm.) 15 x 16=240 so the naswer is 240 Miles!

Hope This Helps!

Answer:

240 miles.

Step-by-step explanation:

First, you are going to determine the ratio of centimeters to miles (1:15)

Since there are 15 miles to every centimeter, you may create an equation like this to help: 15 x c = m (m being miles and c being centimeters)

This means that for every centimeter there are 15 miles.

Since the distance between Town A and Town B is 16 centimeters, you may replace the variable "c" with 16 like so: 15 x 16 = m

Because there are 15 miles for every centimeter, you may multiply the centimeters by 15 to get the distance, using the aforementioned equation of 15 x 16 = m. 15 times 16 is 240.

Therefore there are 240 miles separating Town A and Town B.

Hope this helps!

The Kings HawkA Even the worlds greatest leaders sometimes learn things the hard way. 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 do the circled letters on the outside of the Punnett square in the attached figure represent?
