Phil had a bag containing 90 marbles. He drew out a marble without looking and recorded the color. He then put the marble back in the bag and drew another marble without looking and recorded its color. He continued this for 10 draws. The table shows his results.

Based on the information shown in the table, what is the best estimate for the number of yellow marbles in the bag?

Marbles colors= red , yellow, blue

times chosen= 2, 3, 5

Answers

Answer 1

Answer:

27 yellow marbles

Step-by-step explanation:

3 yellow out of 10 marbles gives a probability of 3/10 to pick a yellow marble.

So, if y = no. of yellow marbles in the bag, then

y/90 = 3/10

10y = 270

y = 27 yellow marbles

The fourth is equal to 16

The required, greatest volume among the given number is [tex]16^{3/2}[/tex].

What is simplification?

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.

A culture of 100 bacteria grows at a continuous rate of 20%. Two hours later. 60 of the same type of bacteria are placed in a culture that allows a 30% growth rate. After how many hours do both cultures have the same population? Explain your answer.

Answers

Answer:

Both cultures will have the same population after 11 hours.

Step-by-step explanation:

Exponential equation for population growth:

The exponential equation for population growth is given by:

[tex]P(t) = P(0)(1+r)^t[/tex]

In which P(0) is the initial population and r is the growth rate, as a decimal.

A culture of 100 bacteria grows at a continuous rate of 20%.

This means that [tex]P(0) = 100, r = 0.2[/tex]. So

[tex]P(t) = P(0)(1+r)^t[/tex]

[tex]P_{1}(t) = 100(1+0.2)^t[/tex]

[tex]P_{1}(t) = 100(1.2)^t[/tex]

The other culture starts to hours later, and we want to take that time as a parameter. So

[tex]P_{1}(2) = 100(1.2)^2 = 144[/tex]

Which means that when culture 2 growth starts, the population size of culture 1 is described by the following equation:

[tex]P_{1}(t) = 144(1.2)^t[/tex]

Two hours later 60 of the same type of bacteria are placed in a culture that allows a 30% growth rate.

This means that [tex]P(0) = 60, r = 0.3[/tex]. So

[tex]P(t) = P(0)(1+r)^t[/tex]

[tex]P_{2}(t) = 60(1+0.3)^t[/tex]

[tex]P_{2}(t) = 60(1.3)^t[/tex]

After how many hours do both cultures have the same population?

This is t for which:

[tex]P_{1}(t) = P_{2}(t)[/tex]

So

[tex]144(1.2)^t = 60(1.3)^t[/tex]

[tex]\frac{(1.3)^t}{(1.2)^t} = \frac{144}{60}[/tex]

[tex](\frac{1.3}{1.2})^t = \frac{144}{60}[/tex]

[tex]\log{(\frac{1.3}{1.2})^t} = \log{\frac{144}{60}}[/tex]

[tex]t\log{\frac{1.3}{1.2}} = \log{\frac{144}{60}}[/tex]

[tex]t = \frac{\log{\frac{144}{60}}}{\log{\frac{1.3}{1.2}}}[/tex]

[tex]t = 11[/tex]

Both cultures will have the same population after 11 hours.

A cube has edge lengths of 11 ft. What is the volume of the cube?

Answers

Answer:

1331 ft³

Step-by-step explanation:

The volume of a cube = (edge length)³

From the above question,

Edge length = 11 ft

The volume of the cube = (11 ft)³

= (11 ft × 11 ft × 11 ft)

= 1331 ft³

The volume of the cube = 1331 ft³

The volume of a cylinder is 117.1 cubic feet, and its height is 15 ft. Find the diameter of the base of the cylinder.

Answers

Answer:

3.15 ft

Step-by-step explanation:      

                                                                                              V

Volume of a cylinder:  πr²h.  Solving for r², we get r² = ---------

                                                                                             πh

Here, we get r² = (117.1 ft³) / (3.14·15 ft) = 2.48 ft² and r = √(2.48 ft²), or

1.58 ft, so that the diameter is 2r, or 3.15 ft

The diameter of the base of the cylinder is 3.15 ft.

The two triangles are similar, so [tex]\triangle{NPO} \sim \triangle{YZO}[/tex].

Vertex N matches up with vertex Y.

Vertex P matches up with vertex Z.

Vertex[tex]\frac{NO}{YO}=\frac{1}{4}\\\\\frac{x}{124}=\frac{1}{4}\\\\4x=124\\\\x=31[/tex] O matches up with itself.

Corresponding sides are in proportion.  To find the proportion between the two triangles, you use known sides from each.

[tex]\frac{NP}{YZ}=\frac{23}{92}=\frac{1}{4}[/tex] meaning the small triangle is 1/4 the size of the large one.

To find  x , notice that it is side NO which corresponds to side YO from the large triangle.

Ashley average is a 85, but she forgets to do her finals. Which is the 20% of her grade. What is her final average now?

Answers

Answer:

Her final average now is 68.

Step-by-step explanation:

In order to find the grade average, you have to multiply each item for its percentage and add the results. Since the statement indicates that the final is 20% of the grade and she forgot to do it, that means that she got 0 for that 20%. Also, we can say that the average she has of 85 represents 80% of her grade and you have to multiply the average for the percentage:

85*0.8= 68

According to this, the answer is that her final average now is 68.

whats the answer for 18, tysm the list of actions bellow are examples of what Read the story The Heartbeat of New York.Music was at the heart of New York City. Whether listening to a street performer or hearing the cacophony of taxi horns, visitors and residents could feel the city's rhythm. Pedro was a New Yorker who loved to dance to the music of the city. He stomped out a beat with his feet, clapped a rhythm with his hands, and sang as he waited for the subway. Often, Pedro listened to street musicians performing on guitars, saxophones, or drums and wished that he could play a musical instrument.One day, Pedro learned that Carnegie Hall, a famous venue for musicians, was holding student concerts. Children would spend the year learning about instruments, orchestras, and how to play the recorder. Then, they would perform in a massive concert at Carnegie Hall. Pedro was beside himself with excitement, as he realized that his ambitious dream would come true!Pedro's father registered him in the program, and Pedro began to practice the recorder every day. At first, Pedro found the recorder very challenging to learn. He kept blowing too hard, which made the recorder squeak, and he kept forgetting where to place his fingers. After one practice session, Pedro slammed down his instrument and dashed to his room. When his father arrived, Pedro explained that the recorder was too onerous, so he had reversed his decision and would not be participating in the concert after all. Pedro's father lowered himself onto Pedro's bed, looking troubled."I know how excited you were about playing at Carnegie Hall," Pedro's father said. "It's an amazing opportunity, and I would hate for you to give up because the recorder is hard to learn. In life, many things are difficult, but you won't know all that you are capable of unless you try. Right now, you need to keep on trying, and eventually, it will get easier."Pedro was not happy about his father's advice because quitting was easier than trying, but he agreed to continue practicing. After weeks of practice, Pedro began to notice a difference. He was able to play the low notes without squeaking, and his fingers knew which positions they needed to be in to make each note. Playing the recorder became fun!At the end of the year, Pedro proudly took his place at Carnegie Hall beside other young musicians. When the conductor lifted his baton, Pedro raised his recorder to his mouth, along with hundreds of other students. As the orchestra began to play, Pedro heard his recorder join with the others to create a beautiful melody. There, in Carnegie Hall, Pedro felt the heartbeat of New York.What is the theme of The Heartbeat of New York? aPlaying any type of instrument can be rather difficult. bIf you never give up, your dreams can come true. cWhen you play the recorder, you will hear squeaks. dMusic has the power to encourage others to dream.
