To find the fraction = 14, multiply or divide both the numerator and denominator of 14 by the same number.

The fraction 14 can be written as 14/1.

Multiplying the numerator and denominator of 14/1 by 2 gives:

28/2 = 14

Multiplying the numerator and denominator of 14/1 by 3 gives:

42/3 = 14

Multiplying the numerator and denominator of 14/1 by 4 gives:

1. To get a systematic sample with a random number table, divide the population size by the desired sample size to obtain the sampling interval, select a random starting point from the first n values where n is the sampling interval, and choose every nth value until the sample size is reached.

2. The nth value is found by dividing the population size by the desired sample size.

Determine the total number of items in the population (N) that you want to sample from. Decide on the desired sample size (n) that you want to obtain from the population.

Calculate the sampling interval (k) by dividing the population size by the desired sample size: k = N / n. Choose a random starting point between 1 and k.

Select every kth item in the population from the starting point until the desired sample size is reached. If the last selection exceeds the population size, start again from the beginning.

The nth value would be the sampling interval (k), which is calculated by dividing the population size by the desired sample size.

Based on the above, the equivalent equations are 4x = 15 and 4x - 15 = 0.Hence options A and C are correct.

To determine which equations are equivalent to 3x + 5 = 20 - x, we need to simplify and manipulate the original equation until it has the same form as the other equations. Here's how we can do it:

3x + 5 = 20 - x

Add x to both sides:

4x + 5 = 20

Subtract 5 from both sides:

4x = 15

So the equation 4x = 15 is equivalent to 3x + 5 = 20 - x.

What is Function ?

In mathematics, a function is a rule that associates each input value (also known as the independent variable) with a unique output value (also known as the dependent variable). It is a mathematical object that takes one or more input values and produces an output value.

The input values are usually taken from a set called the domain, and the output values are taken from a set called the range.

We can use the given formula to find the value of f(3) as follows:

f(2) = f(1) + 0.25f(1) = 4.0 billion + 0.25(4.0 billion) = 5.0 billion

f(3) = f(2) + 0.25f(2) = 5.0 billion + 0.25(5.0 billion) = 6.25 billion

Therefore, the value of f(3) is 6.25 billion, which is option B.

Answer:408.4

Step-by-step explanation:

To solve the equation \begin{equation}-\log{\left(x^2 - 15\right)} = \log{\left(2x\right)}\end{equation}, the following steps can be taken:

Apply the logarithmic identity log(a) = log(b) if and only if a = b to obtain the equation x^2 - 15 = 2x.

Move all the terms to one side of the equation to get x^2 - 2x - 15 = 0.

Factor the quadratic expression to obtain (x - 5)(x + 3) = 0.

Use the zero product property, which states that if the product of two factors is zero, then at least one of the factors must be zero, to get x - 5 = 0 or x + 3 = 0.

Solve for x in each equation to obtain x = 5 or x = -3.

Therefore, the steps to solve the equation log(x^2 - 15) = log(2x) from 1 to 5 are:

Apply the logarithmic identity to get x^2 - 15 = 2x.

Move all the terms to one side of the equation to get x^2 - 2x - 15 = 0.

Factor the quadratic expression to obtain (x - 5)(x + 3) = 0.

The length, breadth, and height of the rectangular block are 256 cm, 192 cm, and 320 cm respectively.

To calculate the length, breadth, and height of a rectangular block whose ratio is 4:3:5 and its volume is 3840 cm3,

follow the steps below:

The ratio of length, breadth, and height is 4:3:5 respectively.

Therefore, assume the length to be 4x, the breadth to be 3x, and the height to be 5x, where x is the common factor.

Then, the volume of the block is calculated as:

Volume = length × breadth × height= 4x × 3x × 5x= 60x³

Since the volume of the block is 3840 cm³, we can equate the equation above to 3840 and solve for x, then find the

length, breadth, and height.

60x³ = 3840 x³ = 3840/60 x³ = 64

Length = 4x = 4 × 64 = 256 cm

Breadth = 3x = 3 × 64 = 192 cm

Height = 5x = 5 × 64 = 320 cm

This tells us that these three angles can be arranged in a straight line, but they cannot form a triangle.

In a valid triangle, the sum of the two smaller angles must be greater than the measure of the largest angle. However, in this case, the sum of the two smaller angles (30 degrees and 45 degrees) is only 75 degrees, which is less than the measure of the largest angle (105 degrees).

the fertilizer bag states that 5 1/2 bags are required for 1 acre. then Jasper needs 33/8 bags of fertilizer to fertilize his lawn.

To solve this problem, you need to find out how many bags of fertilizer Jasper needs to fertilize his lawn, which is 3/4 of an acre in size.

To do this, you need to use the information given on the fertilizer bag, which states that 5[tex]\frac{1}{2}[/tex]  bags are required for 1 acre of land.

You can then set up a proportion to find out how many bags Jasper needs. Since Jasper's lawn is 3/4 of an acre in size, you can set up the proportion as follows:

5 [tex]\frac{1}{2}[/tex] bags / 1 acre = x bags / 3/4 acre

To solve for x, you can cross-multiply and simplify:

5 1/2 bags * 3/4 acre = x bags * 1 acre

(11/2) * (3/4) = x

(33/8) = x

Therefore, Jasper needs 33/8 bags of fertilizer to fertilize his lawn. You would multiply in this problem to solve for the unknown variable, x, which represents the number of bags of fertilizer that Jasper needs.

A square matrix's related scalar value is known as a determinant. It is calculated based on the matrix's components using a specified formula. The determinant has several uses in linear algebra, including the resolution of systems of linear equations, the discovery of eigenvalues and eigenvectors, and the assessment of invertibility. If and only if a matrix's determinant is nonzero, the matrix is invertible. The determinant is also employed in other branches of mathematics, such as differential geometry and the determination of the volume of parallelepipeds.

The determinant of the matrix is calculated using the formula:

Given that √7 is a solution to the equation x² = 7, we can use this equation to find a decimal approximation of √7 that satisfies the given condition.

First, we can estimate that √7 is between 2.5 and 3, since 2² = 4 < 7 and 3² = 9 > 7.

Next, we can try using a decimal approximation of √7, such as 2.6 or 2.7, and square it to see if the result is between 6.9 and 7.1.

If we try 2.6, we get:

(2.6)² = 6.76

Since this is less than 6.9, we can try a larger value, such as 2.7:

(2.7)² = 7.29

Since this is greater than 7.1, we can try a value between 2.6 and 2.7, such as 2.65:

(2.65)² = 7.0225

We can approach this problem by first finding the two perfect squares that 240 lies between:

15^2 = 225 and 16^2 = 256.

Since the square root of 240 must lie between the square root of 225 and 256, we can choose the number that is closest between 15 and 16.

To do this, we can calculate the distance between the square root of 240 and each of the two numbers:

The distance between 15 and the square root of 240 is |15 - sqrt(240)| = 1.18

The distance between 16 and the square root of 240 is |16 - sqrt(240)| = 0.34

Therefore, 16 is closest to the square root of 240.

Standard deviation = sqrt(variance) = sqrt(40,000) = 200

z = (x - μ) / σ

where z is the standardized value, x is the value of interest, μ is the mean, and σ is the standard deviation.

For x = 1000:

z1 = (1000 - 1100) / 200 = -0.5

For x = 1520:

z2 = (1520 - 1100) / 200 = 2.1

Using a calculator, we can use the normal cdf function with the z-scores to find the area between z1 and z2:

P(z1 < z < z2) = normal cdf(-0.5, 2.1) ≈ 0.9192

With given coordinates of the endpoints of line, the length is 17.75 units.

What are coordinates ?

Coordinates are a set of numbers that describe the position or location of a point in space. In a two-dimensional plane, coordinates are typically represented by two values, an x-coordinate and a y-coordinate, which describe the horizontal and vertical position of a point, respectively.

Now,

The length of a line segment in a two-dimensional plane can be calculated using the distance formula:

d=√[(x₂ - x₁)² + (y₂ - y₁)²]

where (x₁, y₁) and (x₂, y₂) = coordinates of the endpoints of the line segment

In this case, the coordinates of the endpoints are (4.25, 6.25) and (22, 6.25)

d = √[(22 - 4.25)² + (6.25 - 6.25)²]

= √[(17.75)² + (0)²]
