Clara is playing a board game. The game has five cards with a different shape on each card. When a player draws a card, they go to the next spot on the board that has the shape shown on the card. The cards are shown below.

Complete the table by matching the number of trials and the expected frequency for each shape.

Answers

Answer: See the attached image below

==============================================

Explanation:

The problem doesn't state this, but I'm assuming we have the same amount of each type of card. For instance, we could have 10 of each card.

The probability of getting any one type is 1/5 = 0.2 since there's one type we're after out of 5 shapes total. If we had 10 of each card, then the probability of getting a diamond is 10/50 = 1/5 = 0.2; note how there are 5*10 = 50 cards total.

If we expect 50 diamonds, then this must mean that 50/0.2 = 250 trials were conducted. You have the correct answer for the first box.

If we do 200 trials, then we expect (1/5)*200 = 40 cards would be a pentagon card. That explains row 2.

If we do 150 trials, then we expect (1/5)*150 = 30 star cards. The value 30 goes in the second box.

The value 300 goes in the third box. We find this by computing 60/0.2, or we can multiply 5 by 60. Note how (1/5)*300 = 60.

Lastly, if we conduct 50 trials, then we expect 10 circle cards because (1/5)*50 = 10.

Side note: the values 100 and 20 are not used.

Choose the best method to solve the system of linear equations. Then choose a reason to justify your answer choice. x−3y=6 x−3y=−3

Answers

Answer:

No solution.

Step-by-step explanation:

The given equations are :

x−3y=6 ...(1)

x−3y=−3 ...(2)

We need to solve the above equations.

The above two lines are parallel. Forparallel lines,

[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}\ne \dfrac{c_1}{c_2}[/tex]

Here,

[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}[/tex]

It means, the above equations have no solution.

Z + y + 0 = z + y equals to what?

Answers

Answer:

y=0/0

Step-by-step explanation:

Step 1: Add -y to both sides.

y+z+−y=y+z+−y

z=z

Step 2: Add -z to both sides.

z+−z=z+−z

0=0

Step 3: Divide both sides by 0.

0/0=0/0

y=0/0

Answers

Answer:

x=55

Step-by-step explanation:

90 degree angle

Susan is making a large batch of salsa.
She can spend no more than $30 on ingredients. She buys all ingredients except for tomatoes for $6.50. Tomatoes cost $2 per pound.
How many pounds of tomatoes,x, can she buy?

INEQUALITY THAT REPRESENTS THIS SITUATION
30>= 6.50+2x

Answers

Answer:

She can buy 0 to 11.75 pounds of tomatoes.

Step-by-step explanation:

Consider the provided information.

It is given that Susan can spend no more than $30 on ingredients. She buys all ingredients except for tomatoes for $6.50. Tomatoes cost $2 per pound.

It means she can only spend less than or equal to $30. Let x be the pounds of tomatoes she can buy.

So, the required inequality should be:

[tex]30\leq 6.50+2x[/tex]

Now simplify the inequality.

[tex]30-6.50\leq 2x[/tex]

[tex]23.5 \leq 2x[/tex]

[tex]11.75\leq x[/tex]

Hence, she can buy 0 to 11.75 pounds of tomatoes.

Papa John's sold 236 pizzas last night. The manager wants to give the workers a prize if they can increase the number of pizzas sold by 24%. How many pizzas do they need to sell to get the prize? (Remember if there is a decimal to round up to the next whole number so 13.2 would become 14)

Answers

11 cheese pizzas and 43 pepperoni pizzas

Answer:

You need to increase the amount of pizza sold by 24%, you can do it one of two ways:

236*0.24 = 56.64 and then do 236 + 56.64 = 292.64

(this way you find out what 24% of 236 is and then add it to 236 to get an increase of 24% )

or you can do this:

236 *1.24 = 292.64

(this way you're finding out what 124% of 236 is. I find this way easier because there's less steps. it works because you're still finding out what 24% is, you're just keeping the 236 there)

either way they need to sell 293 pizza's to get the prize

What is the slope of the line graphed on the coordinate plane?
Put your answer in the box

Answers

Answer:

-8

Step-by-step explanation:

As we know, slope is rise over run. We count up and over until we get to the next dot. To get to the next dot, we count 8 up and -1 over (since we go to the left, not the right). We can put this in a fraction (rise/run). That gets us 8/-1, which can be simplified to -8.

Find the perimeter of a 35° slice of pizza that has a radius of 8 inches.

Answers

9514 1404 393

Answer:

20.9 inches

Step-by-step explanation:

The perimeter length is the sum of the lengths of the two straight edges and that of the curved edge.

P = r + r + rα . . . . . where α is the central angle in radians

35° is (35°/180°)π radians, about 0.6109 radians

Then the perimeter is ...

P = r(2 +α) = (8 in)(2 +0.6109) ≈ 20.9 in

The perimeter of the slice is about 20.9 inches.

I don't know if I'm right or not. I think it's C, but I'm not too sure. The Ancient Chinese were famous for their inventions and technology.

Other inventions led to great feats of engineering like the Grand Canal and the Great Wall of China.Firing a rocket using gunpowder The Diamond Sutra is the world's oldest Printed BookHere are some of the notable inventions and discoveries made by the engineers and scientists of Ancient China:Silk - Silk was a soft and light material much desired by the wealthy throughout the world. It became such a valuable export that the trade route running from Europe to China became known as the Silk Road. The Chinese learned how to make silk from the cocoons of silkworms. They managed to keep the process for making silk a secret for hundreds of years.Paper - Paper was invented by the Chinese as well as many interesting uses for paper like paper money and playing cards. The first paper was invented in the 2nd century BC and the manufacture later perfected around 105 AD. (Modern paper, not papyrus paper).Printing - Wood block printing was invented in AD 868 and then moveable type around 200 years later. This was actually hundreds of years before the invention of the printing press by Gutenberg in Europe.The Compass - The Chinese invented the magnetic compass to help determine the correct direction. They used this in city planning at first, but it became very important to map makers and for the navigation of ships.Gunpowder - Gunpowder was invented in the 9th century by chemists trying to find the Elixir of Immortality. Not long after, engineers figured out how to use gunpowder for military uses such as bombs, guns, mines, and even rockets. They also invented fireworks and made great beautiful displays of fireworks for celebrations.Boat Rudder - The rudder was invented as a way to steer large ships. This enabled the Chinese to build huge ships as early as 200 AD, well before they were ever built in Europe.Other - Other inventions include the umbrella, porcelain, the wheelbarrow, iron casting, hot air balloons, seismographs to measure earthquakes, kites, matches, stirrups for riding horses, and acupuncture.Fun Facts Gunpowder, paper, printing, and the compass are sometimes called the Four Great Inventions of Ancient China. Kites were first used as a way for the army to signal warnings. Umbrellas were invented for protection from the sun as well as the rain. Chinese doctors knew about certain herbs to help sick people. They also knew that eating good foods was important to being healthy. Compasses were often used to make sure that homes were built facing the correct direction so they would be in harmony with nature.
