a) 20.9

    The mean is calculated by adding up the scores and dividing the total by the number of scores, it is also called the average.

    First, we can count and see there are 11 players (makes sense for a football team). Adding up the ages gives us 19 + 19 + 20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23 = 230. Divide by 11 and we get a mean of of about 20.9!

b) 30

To figure this out, we will set up an equation that looks like this:

[tex]\frac{19 + 19 + 20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23+x}{12} =22[/tex]

And now we will solve:

[multiply both sides by 12] 230 + x = 264

[subtract 130 from both sides] x = 30

So the age of the new player should be 30!

Have a nice day!

The mass of 1 L of water is 1 kg. The mass of gasoline is 0.68 times the mass of water. What is the mass of the gasoline in a full tank that holds 75 L.

Answers

I’m guessing it would be 51 kg

Hence, the mass of the gasoline in a full tank that holds [tex]75L[/tex] is [tex]680[/tex]grams.

What is the mass?

Mass refers to the quantity of matter in an object. Mass is generally measured by how much something weighs. The more matter something has, the more it will weigh.

Here given that,

The mass of [tex]1[/tex] L of water is [tex]1[/tex] kg. The mass of gasoline is [tex]0.68[/tex] times the mass of water.

As we know,

[tex]1L=1000ml[/tex]

So, [tex]0.68[/tex]×[tex]1000=680grams[/tex]

As per this the mass of water is greater than the mass of gasoline.

Hence, the mass of the gasoline in a full tank that holds [tex]75L[/tex] is [tex]680[/tex]grams.

A 6-pound bag of sugar costs $7.98. What is the unit price?

Answers

Answer:

1.33

Step-by-step explanation:

Lets start by making a quick equation:

Total cost is y, or 7.98, with the weight being 6 pounds. We are looking for the unit price, which will be our x.

7.98 = 6x

Divide 6 by both sides:

7.98 / 6 = 6x / 6

This gets rid of the 6 on the right, so we are left with:

1.33 = x

So the unit price is $1.33 per pound.

Answers

Answer:

The larger angle is 144 degrees and the smaller angle is 36 degrees

Step-by-step explanation:

Because this is a  supplementary angle you have to find out what x is to solve  this equation [tex]2.4x+9.6x=180[/tex]

Because 2.4x and 9.6x are like terms we add them [tex]2.4x+9.6x=12x[/tex]

So now to find x we divide 180 by 12 to get 15  [tex]\frac{12x}{12} =\frac{180}{12}[/tex]

We replace the x with 15 [tex]2.4(15)+9.6(15)=36+144[/tex]

We add 36 and 144 which equals 180

how can you find the product of positive and negative decimals

Answers

(I have attached an example for reference)

1) Product means multiply, so we will multiply the decimal numbers.

2) First multiply both the numbers just the way you multiply two whole numbers.

3) note that WHILE multiplying you DON'T put the decimal point. Put the decimal point once you get your FINAL answer.

4) Once multiplied, count the total number of places after the decimal in both the numbers which were given. i.e, in the example it's 2 decimal places, one decimal place in 24.5 and one in 3.2, which means the total decimal places here are two.

5) now in your answer, start counting the decimal places from the right side of the number. For example in 7840, we start counting two decimal places from the right side of it and stop at 4 and put a decimal point there. This way we get 78•40.

Read the story.The Speech A hush fell over the crowd as Samir approached the stage; he took a deep breath and tried to still the tremble in his hands. He had rehearsed the speech for days, practicing late into the night when the house was quiet. The night before, he had been putting the finishing touches on the speech when his mother snuck up the stairs and stopped by his bedroom door with a mug of tea. It looks like you will need this. Hows it coming? She tucked the long end of her sari under her leg and sat on his bed. The familiar smell that reminded him of trips to India tickled his nose as he took the warm mug from her; he pressed it to his lips and took a long sip. I dont think theyre going to understand it. Its okay if they dont understand it in their brains; its more important that they feel it here. She pressed her hand to his heart. My friends dont know what you went through to get here, and I want to get it just right because I need them to like the story. Your friends will like you no matter what. Practice it one more time, and then you need to get some sleep. He stared at the words that he had painstakingly crafted to tell the story of how his parents had immigrated to the United States from India. Even though he hadnt been born at the time, he could feel the heat on their skin as theyd packed up their belongings in Mumbai and boarded the plane for their new lives. After a twenty20-hour flight, they landed in the chill of Chicago; they hadnt brought enough heavy clothes with them and had to buy sweatshirts from the airport store before stepping out into snow for the first time. His mother had danced around in the swirling white like a fascinated child, tasting flakes on her tongue before the cab whisked them away to their new lives. He didnt know how his parents got by in those early days of loneliness and isolation, when they didnt know their neighbors and couldnt find their favorite spices or flavors in the local grocery store. He imagined his homesick mother making pungent curry in the tiny kitchen of the apartment that was their first homecurry that she didnt share with anyone except her husband because he was the only person she knew. Eventually they had made a life there, and one year after theyd brought Samir home as a newborn, his younger sister Aarti was born, and they became a family of four. Each year that his parents lived in Chicago, they spoke about Mumbai like it was more of a memory. Samir grew up hearing stories of Mumbai and taking summer trips where he heard his parents speak a language that was clumsy on his own English-speaking tongue. He couldnt imagine leaving his life and moving herefar away, but he knew that his parents had done it for him and his sister. It was the ultimate sacrifice, his mother had said, but it was worth it. When he had finished rehearsing his speech for his mother, she dabbed her face, and he knew she was crying. He didnt need to ask how the speech washer expression told him that it was perfect. Samirs thoughts came back to the present moment as he cleared his throat and stepped onto the stage in front of the entire middle schoolhis friends and teachers were all here. He had often felt different from his peers and wanted so much for them to understand his story. But looking out into the crowd at all the different faces he realized that his peers must have their own stories to tell as well. Perhaps they wanted to be understood, too. He realized the only way to be understood is to share those stories. Perhaps if he shared his own story, others would share theirs, too. Perhaps it would help them to understand one another. He found his moms eyes in the middle of the front row. When she nodded, he began. Im going to tell the story of how my parents became American citizens.How does the theme that stories can help us understand one another develop in "The Speech"?The theme develops through the author's depiction of how Samir changes from feeling different and separate from his peers to feeling not so different and comfortable with them after his mother tells him their family story.The theme develops through the author's depiction of how Samir learns to appreciate his classmates' different stories by listening to what their families went through.The theme develops through the author's depiction of how Samir feels more comfortable and confident delivering his speech after his mother offers him some tea and listens to what he has to say.The theme develops through the author's depiction of how Samir feels different and misunderstood before giving his speech but feels more comfortable and accepted once he realizes that everyone has a story of their own.
