All of your revenues and expenses are listed in your profit and loss statements. They also show whether operating expenses have been covered by profits earned by your business. In that case, you could claim that your business has made money. The profit and loss statement displays the profitability of a company.

We can start solving this problem by setting up an equation for the value of the TV over time. Let V be the value of the TV in dollars and t be the time in years. Then, we have:

V(t) = 1900 - 225t

We want to find the time it takes for the TV to be worth half of its original value, which means we want to find t when V(t) = 950. So, we can set up the following equation:

950 = 1900 - 225t

Solving for t, we get:

t = (1900 - 950) / 225

t = 4.22 years (rounded to two decimal places)

Therefore, it will take approximately 4.2 years for the television set to be worth half of its original value.

Step-by-step explanation:

Newton's first law of motion, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue in motion with a constant velocity, unless acted upon by an external force.

If you are standing on separate sheets of paper and start running, your body will experience a forward motion. However, the sheets of paper under your feet will initially resist the motion due to friction. The force of friction will create an equal and opposite force, causing the sheets of paper to slide backwards. As you continue to run, the friction between your feet and the paper will decrease, and the sheets of paper may eventually stop sliding and you will continue running with a constant velocity.

This is an example of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. The force you apply to the ground when running is the action, and the force of the ground pushing back on you is the reaction.

Step-by-step explanation:

Simplifying the expression (2+1)2, we can first perform the operation within the parentheses, which gives us:

(2+1)2 = 3 x 2

Then, we can multiply 3 by 2, which gives us:

3 x 2 = 6

Therefore, the simplified expression for (2+1)2 is 6

The sum of their 3 prime numbers is 24.

Let's start by finding the prime numbers that Jimmy, Kimmy, and Timmy are thinking of.

We know that the product of Jimmy's and Kimmy's prime is 34. Since 34 is not a prime number, it must be the product of two prime factors.

The only way to factor 34 as a product of two primes is 2 x 17.

So we know that Jimmy's prime is either 2 or 17, and Kimmy's prime is the other one. We also know that Kimmy's and Timmy's primes multiply to 85. Again, 85 is not a prime number, so it must be the product of two prime factors.

The only way to factor 85 as a product of two primes is 5 x 17.

Therefore, we know that Timmy's prime is 5.

So the three primes are 2, 17, and 5.

The sum of these three primes is 2 + 17 + 5 = 24.

The answer is D: [-4, ∞) and R: [0, ∞)

Imagine you draw a straight line down the middle of a piece of paper. This line is the line of symmetry. Anything you draw on one side of the line is going to have a mirror image on the other side of the line that looks exactly the same.

Now, if you have a point on the line of symmetry, that means the point is exactly in the middle of the line. And since the line is the same on both sides, that means the point is going to be the same on both sides too! So, the point on the line of symmetry stays in the same place and looks the same on both sides of the line.

Step-by-step explanation:

To solve the equation 7x + 5 = 12x - 10, we want to isolate the variable x on one side of the equation. We can do this by adding or subtracting terms from both sides of the equation until we have x by itself.

First, let's simplify both sides of the equation by combining like terms:

7x + 5 = 12x - 10

-7x -7x (subtracting 7x from both sides)

5x + 5 = -10

Next, let's isolate the term with x by subtracting 5 from both sides of the equation:

5x + 5 = -10

-5 -5 (subtracting 5 from both sides)

5x = -15

Finally, let's solve for x by dividing both sides of the equation by 5:

5x = -15

x = -3

Therefore, the solution to the equation 7x + 5 = 12x - 10 is x = -3.

26 = 24 - x

-24 -24 (subtracting 24 from both sides)

2 = -x

Next, let's isolate the variable x by multiplying both sides of the equation by -1:

2 = -x

-1 -1 (multiplying both sides by -1)

-2 = x

Therefore, the solution to the equation 26 = 24 - x is x = -2.

2(6x - 7) = 10

12x - 14 = 10

Next, let's isolate the term with x by adding 14 to both sides of the equation:

12x - 14 = 10

+14 +14 (adding 14 to both sides)

12x = 24

Finally, let's solve for x by dividing both sides of the equation by 12:

12x = 24

x = 2

Therefore, the solution to the equation 2(6x - 7) = 10 is x = 2.

Answer:

So, Fatima's curtain company needs to purchase 248 feet of fabric to make the curtains for the local hotel.

Step-by-step explanation:

To find out how many feet of fabric Fatima's curtain company needs, we first need to calculate the total length of fabric required for all 62 curtains.

Each curtain is 48 inches long, so the total length of fabric required for one curtain is:

48 inches = (48/12) feet = 4 feet

Therefore, the total length of fabric required for 62 curtains is:

62 curtains x 4 feet/curtain = 248 feet of fabric

So, Fatima's curtain company needs to purchase 248 feet of fabric to make the curtains for the local hotel.

The value of the transformed function after a vertical stretch in the y direction is h ( x ) = k ( | x | - 3 ) , where k is the scale factor

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the parent function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = ( | x | - 3 )   be equation (1)

Now , when the function is stretched in the y direction , we get

Vertical stretch by a factor k: y = k × f(x)

On simplifying , we get

Let the transformed function be represented as h ( x )

where the value of h ( x ) is

Let the scale factor of stretching be k

h ( x ) = k ( | x | - 3 )

Hence , the transformed function is h ( x ) = k ( | x | - 3 )

In probability and statistics, a probability mass function is a function that gives the probability that a discrete random variable is exactly equal to some value

Given is that there is a chance that a bit transmitted through a digital transmission channel is received in error. Let X denote the number of bits in error in the next four bits transmitted. Suppose the probability mass function is given by -

Pr(X = 0) = 0.55

Pr{X = 1) = 0.22

Pr(X = 2) = 0.13

Pr(X = 3) = 0.08

We can find the probabilities as -

{ 1 } - the probability that two or fewer bits are transmitted in error :

P{E} = P(0) + P(1) + P(2)/∑P{n}

P{E} = 0.9/1

P{E} = 0.9

{ 2 } - the probability that at least one bit is transmitted in error -

P{E} = P(1) + P(2) + P(3) + P(4)/∑P{n}

Using the given restrictions we can see that there are 37 balls on the box.

Let's assume that the total number of balls is B.

We know that in the box there are more than 25 and fewer than 40 tennis balls, so we have the inequality.

25 < B < 40

If we count in 3's, then there is one left over, so we can write:

B = 3*n + 1   (where n is an integer number)

And if we count in 5's there are 2 leftovers:

B = 5*m + 2  (where m is an integer, from this we conclude that the number ends in a 2 or a 7)

Then we have 3 restrictions:

25 < B < 40

B = 3*n + 1

B = 5*m + 2

notice that if n = 12

B = 3*12 + 1 = 37

if m = 7

B = 5*7 + 2 = 37

and 37 is a solution of the inequality, then we conclude that there are 37 balls on the box.

The real GDP per capita increased by 28% from 2012 to 2013.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

We need to Write the percent as a fraction in simplest form

16.24%

So, we can rewrite it as;

16.24 / 100

16 and 24/100 or 16 6/25

So the percent as a fraction is 16 6/25

We are given that;

The table with GDP deflator and population

Now,

i. The percentage change in nominal GDP from 2012 to 2013 can be calculated as follows:

[(Nominal GDP in 2013 - Nominal GDP in 2012) / Nominal GDP in 2012] x 100

= [(112 - 75) / 75] x 100

= 49.33%

Therefore, nominal GDP grew by 49.33% from 2012 to 2013.

ii. Real GDP is nominal GDP adjusted for inflation. To find real GDP, we need to use the GDP deflator:

Real GDP (in billions) = Nominal GDP (in billions) / (GDP Deflator / 100)

In 2012: Real GDP = 75 / (50 / 100) = £150 billion

In 2013: Real GDP = 112 / (54 / 100) = £207.41 billion

iii. The percentage change in real GDP from 2012 to 2013 can be calculated as follows:

[(Real GDP in 2013 - Real GDP in 2012) / Real GDP in 2012] x 100

= [(207.41 - 150) / 150] x 100

= 38.27%

Therefore, real GDP grew by 38.27% from 2012 to 2013.

iv. To determine if the growth in nominal and real GDP increased the standard of living, we need to look at the change in real GDP per capita. Real GDP per capita is calculated by dividing real GDP by the population:

Real GDP per capita in 2012 = 150 / 50 = £3 billion

Real GDP per capita in 2013 = 207.41 / 54 = £3.84 billion

The percentage change in real GDP per capita can be calculated as follows:

[(Real GDP per capita in 2013 - Real GDP per capita in 2012) / Real GDP per capita in 2012] x 100

= [(3.84 - 3) / 3] x 100

= 28%

An expression for e[z] by the given data is  E[z] = (n-1)/n * H_n-1.

An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.

If the initial term of a sequence is 'a' and the common difference is of 'd', then we have the arithmetic sequence as:

a, a + d, a +  2d, ... , a + (n+1)d, ...

Its nth term is

T_n = a + (n-1)d

And thus, the common difference is

T_nT_{n+1} - T_n

for all positive integer values of n.

Balls are thrown uniformly and independently in all bins

Now,

We can express z as the sum of these binary random variables:

[tex]z = z_1 + z_2 + ... + z_{n-1}[/tex]

The random variables z_i are not independent, since the probability of throwing a ball into a bin that already has at least one ball in it depends on the number of balls already in the bin.

However, we can still use the linearity of expectation to calculate the expected value of z:

[tex]E[z] = E[z_1 + z_2 + ... + z_{n-1}][/tex]

By the linearity of expectation, we can distribute the expectation over the sum:

[tex]E[z] = E[z_1] + E[z_2] + ... + E[z_{n-1}][/tex]

Using these probabilities, we can calculate the expected value of each z_i:

[tex]E[z_i] = 1 * P(z_i=1) + 0 * P(z_i=0)= P(z_i=1)[/tex]

= (i-1)/n-i+1

Substituting this into the expression for E[z], we get:

[tex]E[z] = (1-1/n) + (2-1/n-1) + ... + (n-1-1/2)= (n-1)/n + (n-1)/n-1 + ... + 1/2[/tex]

This is a finite arithmetic series with n-1 terms, with first term (n-1)/n and common difference -1/n. Using the formula for the sum of an arithmetic series, we get:

[tex]E[z] = (n-1)/n + (n-2)/n + ... + 1/n= (n-1)/n * (1 + 1/2 + ... + 1/(n-1))[/tex]

This sum is known as the n-th harmonic number, denoted H_n.
