Using proportions and the percentage concept, it is found that:

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using a rule of three, that can be either direct(cross multiplication) or inverse(line multiplication), deriving from proportional relationships. One example of application of proportions is for percentage problems.

This is because a percentage of an amount a divided by a total amount b is given by the following proportion:

P = a/b x 100%.

From the image, we have that 3 out of 12 apples are of the Jonagold variety, hence:

3/12 x 100% = 0.25 x 100% = 25%.

Each apple in the image is equivalent to 7 apples, hence:

9 x 7 = 63.

63 apples are not of the Jonagold variety.

Alan drive if he uses 4 gallons of gas is 75 miles distance

The following function calculates the distance (in miles) he travels on gallons of gas. D(g)=25g

Where D(g) is the distance traveled in gallons.

and g denoted the quantity of gasoline used

We are asked to calculate the distance traveled in three gallons of gasoline. To do this, we will set the value of g to 3 in our function.

D(3)=25 x 3 = 75

As a result, Chris's automobile traveled 75 miles on three gallons of petrol.

The equity capital the firm raise from this sale is $15 million.

Equity capital refers to the funds paid into a business by investors in exchange for common or preferred stock. It can be solved by subtracting the total liabilities from the total assets.

Equity Capital = Total Assets – Total Liabilities

If a company sold 1 million shares of common stock at $10 book value, then its total liabilities is $10 million.

If the stock price then rose to $25 per share on the New York stock exchange, then the total assets is $25 million.

Equity Capital = Total Assets – Total Liabilities

Equity Capital = $25 million – $10 million

The scatterplot is the correct answer.

A scatter plot uses dots to represent values for two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables.

The dots in a scatter plot not only report the values of individual data points but also patterns when the data are taken as a whole.

Identification of correlational relationships is common with scatter plots. In these cases, we want to know, if we were given a particular horizontal value, what a good prediction would be for the vertical value.

The magnitude of the sum of these two vectors is approximately 11.791 units.

In this question we have the representations of two vectors on a Cartesian plane, of which we must find the magnitude of the two vectors. There are different methods to find it, we decide to use a vectorial method. First, sum the two vectors:

R(x, y) = A(x, y) + B(x, y)

R(x, y) = 7.70 · (cos 27.8°, sin 27.8°) + 16.3 · (- sin 20°, - cos 20°)

R(x, y) = (6.811, 3.591) + (- 5.574, - 15.317)

R(x, y) = (1.237, - 11.726)

Second, use the Pythagorean theorem:

R = √[1.237² + (- 11.726)²]

R ≈ 11.791

The magnitude of the sum of these two vectors is approximately 11.791 meters.

The values of x are 8, -11/2 + ✓243i/2, -11/2 - ✓243i/2

[tex] {(x + 1) }^{3/2} [/tex] - 2 = 25

Adding 2 on both the sides of the equation we get

[tex] {(x + 1) }^{3/2} [/tex] - 2 + 2 = 25 + 2

[tex] {(x + 1) }^{3/2} [/tex] = 27

On squaring both the sides of the equation we get

[tex] {x + 1}^{3/2 \times 2} [/tex] = 27²

(x + 1)³ = 729

Now, using the identity (a + b)³ = a³ + b³ + 3ab(a + b), we get

x³ + 1 + 3x² + 3x = 729

x³ + 3x² + 3x - 728 = 0 : Equation 1

By hit and trial method x = 8 is the solution of the equation 1.

Now, by remainder theorem we can write the equation 1 as

x³ + 3x² + 3x - 728 = (x - 8)(x² + 11x + 91) + 0

On solving quadratic equation x² + 11x + 91, we get

x = -b+✓(b² - 4ac)/2a and -b-✓(b² - 4ac)/2a

x = -11+✓(11² - 4×1×91)/2×1 and -11-✓(11² - 4×1×91)/2×1

x = -11+✓(121 - 364)/2 and -11-✓(121 - 364)/2

x = -11+✓(-243)/2 and -11-✓(-243)/2

x = -11/2 + ✓243i/2, -11/2 - ✓243i/2

Thus, the values of x are 8, -11/2 + ✓243i/2, -11/2 - ✓243i/2

Answer: The value of p(x) = (-2,6) or p(x) = (-2,0)

Step-by-step explanation:

Given that,

p(x) = x^3-4x^2-8x

p(x) = [tex]x^{3}[/tex] - [tex]4x^{2}[/tex] - 8x

and replace with '0'.

x^3-4x^2-8x = 0

Now, factorizing equation is,

(x+2) ([tex]x^{2}[/tex] - 6x) = 0

(x+2) = 0

x= -2

Therefore, x = -2

and,

([tex]x^{2}[/tex] -6x) = 0

([tex]x^{2}[/tex] -6x+0) = 0

using quadratic formula = - [b ± √[tex]b^{2}[/tex]-4ac] / 2a

substitute the values,

a = 1, b = -6 , c = 0

                          p(x) = - [-6 ± √[tex]-6^{2}[/tex]-4.1.0] / 2.1

                           p(x) = - [-6 ± √36-4.1.0] / 2.1

                            p(x) = - [-6 ± √36-(0)] / 2.1

                             p(x) = - [-6 ± √36] / 2.1

                             p(x) = - [-6 ± 6] / 2

                              p(x) = [6 ± 6] / 2

                             p(x) = 3 ± 3

Therefore, p(x) = 3+3 = 6

                  p(x) = 3-3 = 0

So, that we can say the value of p(x) = (-2,6) or p(x) = (-2,0).

The value of x using the properties of logarithm is 1.

What are the various properties of the logarithm?

Out of several properties of logarithms, some of the main properties are given below:

Product Rule

log (ab) = log a + log b

Change of base

log ₇ x = log x / log 7

Power Rule

log a² = 2 log a

Quotient Rule

log (a / b) = log a - log b

Solving the given equation for x

We are given a logarithmic expression: 3/2 log₂4 - ½ log₂x = 3

Using properties of the logarithm, we have

3/2 log₂4 - ½ log₂x = 3

3/2 (2 log 2 / log 2) - ½ (log x / log 2) = 3

3 - ½ (log x / log 2) = 3

½ (log x / log 2) = 0

log x = 0

log x = log 1

On applying exponent both sides, we get,

x = 1

Hence, the value of x is 1.

Answer: y=3(x+3)^3-1

Step-by-step explanation:

The probability that only one of the counter is white is 6/11.

So we know that there are 11 counters, 5 of them are white, 6 are not white.

Let's assume that first we take the white one, the probability is equal to the quotient between the number of white counters and the total number of counters, so we have:

p = 5/11

Now for the second one, we don't want to take a white one, so here the probability is equal to the quotient between the number of non-white counters (6) and the total number of counters (now there are 10, because we took one)

q = 6/10

The joint probability is the product of the individual probabilities, this is:

P = p*q

And, also notice that there are 2 permutations:

So we need to add a factor 2.

P = 2*p*q = 2*(5/11)*(6/10) = 6/11

The probability is 6/11
