Answer:

3/8

Step-by-step explanation:

There is 3/4 of pile and if half is eaten you are left with 3/8.

In Mathematics, when half of a pie (or '1/2') is eaten, the remaining fraction is the other half, which is also '1/2'. This is because a whole pie is considered '2/2', or 'one whole'.

The question is asking about a simple fraction operation in the realm of Mathematics. When you eat half of a pie, it essentially means you've consumed '1 out of 2' parts of the pie, or '1/2'. If this is the case, then the fraction that remains would naturally be the other half, or '1/2' as well.

This is because a whole pie is considered '2 out of 2' parts or '2/2', which equals 1, or 'one whole'. So if you eat half of it ('1/2'), the fraction that remains is the uneaten half, which is also '1/2'.

Answer:

x=-4 and x=6

Step-by-step explanation:

Factor the denominator of the equation and then set them equal to zero and you will get these answers.

The vertical asymptotes of the function f(x) = 7/(x² - 2x - 24) are found at x = 6 and x = -4, which are the values that make the denominator of the function equate to zero.

The function provided is a rational function, namely f (x) = 7/(x² - 2x - 24). To find the asymptotes for this function, we must identify the values of x that will make the denominator equate to zero, as these points result in undefined values within the function.

These points define the vertical asymptotes. To find these, we set the equation x² - 2x - 24 = 0 and solve for x. The solutions to this equation are the x-values of the vertical asymptotes.

By factoring the equation x² - 2x - 24 = 0, we get (x - 6)(x + 4) = 0. Therefore, the function will have vertical asymptotes at x = 6 and x = -4.

Answer:

437,500

Step-by-step explanation:

The percentage value of amount of money spent on radio advertising is given by R = $ 437,500

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the percentage value of amount of money spent on radio advertising be represented as R

Now , the total amount of revenue money = $ 50,00,000

The percentage of money spent on traditional media = 25 %

So , the amount of money spent on traditional media = percentage of money spent on traditional media x total amount of revenue money

On simplifying , we get

The amount of money spent on traditional media = ( 25/100 ) x 5000000

The amount of money spent on traditional media = $ 12,50,000

Now , the percentage of amount spent on radio advertising = 35 %

So , the amount of money spent on radio advertising = ( 35/100 ) x amount of money spent on traditional media

On simplifying , we get

The amount of money spent on radio advertising = ( 35/100 ) x 12,50,000

The amount of money spent on radio advertising = $ 4,37,500

Hence , the amount of money on radio advertising is $ 4,37,500

Answer:

How much water is in an empty glass that is 10cm high and has a diameter of 5 cm ?

= 196,25 cm

Step-by-step explanation:

diameter = 5 cm

radius = 1/2 × diameter

radius = 1/2 × 5 = 2,5

How much water is in an empty glass that is 10cm high and has a diameter of 5 cm?

= π × r × r × high

= 3,14 × 2,5 × 2,5 × 10

= 196,25 cm

The amount of water in an empty glass is 196.43 cubic centimetre.

Given diameter of glass is 5 cm.

So its radius is [tex]\frac{5}{2}[/tex] cm or 2.5 cm.

Height of glass is 10 cm.

Now we know that normal shape of glass is cylindrical,

So volume of glass = volume of cylinder= [tex]\pi r^{2} h[/tex]

= [tex]\frac{22}{7} \times2.5^{2} \times10[/tex]

[tex]= \frac{22}{7} \times6.25\times10[/tex]

[tex]=196.43 cm^{3}[/tex]

Hence the amount of water in an empty glass is 196.43 cubic centimetre.

Answer:

Walt has 37 quarters.  Hank has 33.

Step-by-step explanation:

Solve the given equation for q:

0.25q + 0.25q - 1.00 = 17.50

Simplify this, obtaining:

0.50q = 18.50

Simplifying this by multiplying both terms of this result by 100:

50 q = 1850

Thus, q = 1850/50 = 37

Walt has 37 quarters.  Hank has 33.

Note that 37 + 33 = 70, and that 70($0.25) = $17.50.  So our results are correct.

The statement that's is true is B. A population includes all of the elements from a set of data.

It's should be noted that a population of a given set of numbers consists of all the numbers. During research, a sample is gotten from the entire population and everyone has a chance of being picked.

It should be noted that there are several samples that can be gotten from the population. Also, a measurable characteristic of a population is not referred to as a statistic.

In conclusion, the correct option is B.

The correct statement is B) A population includes all of the elements from a set of data. This is because a population refers to the totality of subjects we wish to study, whereas a sample is a subset from which we collect data. A statistic is a measure of a sample, and a parameter is a measure of a population.

The question pertains to statistical terminology, specifically the definitions of sample, statistic, population, and parameter. B) A population includes all of the elements from a set of data. This statement is TRUE. A population refers to the entire set of subjects or elements that we are interested in studying. The definition can be applied across various contexts, such as all students in a school, all the birds in a forest, or all the cars produced by a factory.

Conversely, a sample is a subset of the population from which data is actually collected. This is because it is often impractical or impossible to collect data from the entire population. A statistic is a characteristic of a sample, such as the mean or standard deviation, which provides an estimate of the corresponding population parameter. A parameter, therefore, is a characteristic that describes the entire population. For instance, if we calculate the average height of a sample of students from a school, that average is a statistic that estimates the average height of the entire school population—an example of a parameter.

Statement A is incorrect because a measurable characteristic of a population is called a parameter, not a statistic. Statement C is incorrect because multiple samples can be drawn from the same population. Statement D is incorrect because a measurable characteristic of a sample is called a statistic, not a parameter.

DNA is akin to a cell's "brain" in that it contains all the instructional genetic information for the cell. The Central Dogma of Molecular Biology details how this information is transmitted within the cell to produce proteins, which ultimately define the cell's structure and function. Cell differentiation and function are determined by environmental signals and gene expression.

The analogy of DNA being like a cell's "brain" suggests that DNA serves a fundamental role in controlling the functions of a cell, much like the brain controls the functions of the body. DNA contains all the hereditary information necessary for protein synthesis, and these proteins determine the structure and function of the cell. The process by which DNA directs protein synthesis involves transcription (where instructions in DNA are converted into messenger RNA), and translation (where ribosomes read this RNA to build proteins based on the sequence of amino acids encoded within the DNA). This mechanism is known as the Central Dogma of Molecular Biology.

Each cell in our body, regardless of its specific role, contains the same DNA. However, the way in which this DNA is expressed – which genes are turned on or off – determines the function and type of the cell. This differentiation process is guided by the cell's environment and the signals it receives. Additionally, it's important to realize that while DNA contains the instructions, it's through the replication process, along with transcription and translation, that living cells are continuously renewing and passing on these instructions. Cells do not arise anew from DNA; instead, every cell comes from the division of a previous cell, carrying the genetic blueprint forward.

Step-by-step explanation:

Got it right

The measure of B'C' after the dilation of 3 is given by the equation BC = 15

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

Given data ,

Let the triangle be represented as ABC

Now , the dilated triangle is represented as A'B'C'

The dilation factor d = 3

The measure of side AB = 4 units

The measure of side BC = 5 units

The measure of side AC = 3 units

Now , after the dilation of 3 , we get

The measure of side A'B' = 12 units

The measure of side B'C' = 15 units

The measure of side A'C' = 9 units

Hence , the measure of side B'C' is 15 units
