A systematic random sample is obtained by choosing a random starting point and then selecting every kth individual from a population to participate in the study. The number of random numbers that must be produced to recognize individuals who are part of the sample is determined by the following formula:n/k is the number of random numbers required to identify the sample population of size n drawn from a population of size N by systematic random sampling.

To provide an example, consider a population of size N= 1000 and a sample of size n= 50. Assume that we must use systematic random sampling with a k=20. The population should be numbered, and the first random number between 1 and 20 is selected. The kth person after the first random number is chosen. This process is repeated for the entire population, with every kth person included in the sample. The number of random numbers generated would be 1000/20= 50. Therefore, to obtain a sample of 50 individuals, we must generate 50 random numbers to recognize each individual who will be included in the sample.

The amount that'll be saved if the television was bought for cash is $1600.

Cash price of television = $10000

Amount paid through hire purchase will be:

= (20% × $10000) + ($800 × 12)

= (0.2 × $10000) + $9600.

= $2000 + $9600.

= $11600

The amount that could have been saved will be:

z >1 for the given inequality for x.

To solve the following inequality for x.

-26 + 13z + 2 > 2 132

Since there is no x in this I'm assuming we are looking for z

Step 1: Simplify both sides

15r - 26 > -13z + 2

Step 2: Add 13z to both sides

15r - 26 + 13z > -13z + 2 + 13z

28 - 26 > 2

Step 3: Add 26 on both sides

28 - 26 + 26 > 2 + 26

28z > 28

Step 4: Divide both sides by 28z / 28 > 28 / 28

z > 1

Hence the answer is z >1 for the given inequality for x.

The equation in standard form where all coefficients are expressed relatively is -x + 0y = 12.

If the slope of a line is undefined, it means the line is vertical. A vertical line does not have a defined slope, but its equation can still be expressed in standard form.

The equation for a vertical line passing through the point (-12, 12) can be written as:

x = -12

In standard form, the equation is typically written as:

x + 0y = -12

However, to express all coefficients relatively, we can multiply the equation by any non-zero constant to make the coefficient of x equal to 1. In this case, we can multiply the equation by -1 to achieve that:

-x + 0y = 12

The Least common denominator of 5/6 is 30.

Using mathematical induction, we have prove that 1+3+5+...+ (2n+1) = (n+1)²

The first step is to verify the base case, which is n=1.

Then, assume that the equation is true for some arbitrary value k, and use that assumption to show that it is true for k+1.

Step 1: Base Case

When n=1,1+3=42=2²

Therefore, the equation holds for n=1

Step 2: Induction Hypothesis

Assume that the equation holds for some value k, so:1+3+5+...+(2k+1) = (k+1)²

Step 3: Inductive Step

To show that the equation holds for k+1, we need to add the next term, which is (2k+3):1+3+5+...+(2k+1)+(2k+3) = (k+1)² + (2k+3)

Factoring out (k+2) from the right-hand side gives:(k+2)²+(2k+3) = (k+1)² + (2k+3)

Simplifying the left-hand side gives:k²+4k+4+2k+3 = k²+2k+1+2k+3

The right-hand side simplifies to (k+1)², so:k²+4k+7 = (k+1)²Therefore, the equation holds for k+1 as well.

Step 4: Conclusion

Using the principle of mathematical induction, we have shown that the equation holds for all n greater than or equal to 1.

The likelihood that a randomly selected bag of cement weighs more than 50 is approximately 93.32%

When dealing with normally distributed data, we use the mean and standard deviation to determine the likelihood of certain events occurring. In this case, the mean weight of bags of cement is 53 with a standard deviation of 2.

To find the likelihood that a randomly selected bag has a weight greater than 50, we need to calculate the z-score for 50. The z-score tells us how many standard deviations away a particular value is from the mean.

z = (X - μ) / σ

where X is the value we're interested in (50), μ is the mean (53), and σ is the standard deviation (2).

z = (50 - 53) / 2 = -1.5

A z-score of -1.5 means that a weight of 50 is 1.5 standard deviations below the mean. To find the likelihood of a bag weighing more than 50, we can use a z-table or a calculator to find the area to the right of this z-score.

Looking up a z-score of -1.5, we find that the area to the left is approximately 0.0668, which means the area to the right (the likelihood of a bag weighing more than 50) is:

1 - 0.0668 = 0.9332

Thus, the likelihood that a randomly selected bag of cement weighs more than 50 is approximately 93.32%.

The five vectors in span {v1,v2} are we first multiply each vector component (x, y, and z) of v1 and v2 by a constant and then add them together.

1. v3 = (3v1 + 2v2) = (18 8 −16)

2. v4 = (2v1 + 3v2) = (−12 6 0)

3. v5 = (4v1 + v2) = (0 6 −32)

4. v6 = (−2v1 + 5v2) = (36 10 0)

5. v7 = (−v1 + 4v2) = (−36 8 0)

To calculate the vectors, we first multiply each vector component (x, y, and z) of v1 and v2 by a constant and then add them together. For example, for v3 we multiplied v1 by 3 and v2 by 2 and then added the components together to get the vector (18 8 −16). We performed similar calculations for the other vectors.

The given Polynomial expression is (5x³−2x²y+4y)−(x²y+4y−y³). Simplifying the expression, we obtain 5x³−2x²y+4y−x²y−4y+y³. Combining like terms, the final answer is 5x³−3x²y−y³.

The expression (5x³−2x²y+4y)−(x²y+4y−y³) can be simplified by applying the distributive property and combining like terms.

First, distribute the negative sign inside the parentheses to each term inside it. This gives us (5x³−2x²y+4y)−x²y−4y+y³.

Next, combine like terms. In this case, we have -2x²y and -x²y, which can be combined to give us -3x²y. We also have 4y and -4y, which cancel each other out. Finally, we have y³ as a separate term.

Putting it all together, the simplified expression becomes 5x³−3x²y−y³.

Therefore, the final answer is 5x³−3x²y−y³.

I don't think there would be any asymptotes because there are no denominators.

Step-by-step explanation:

The two numbers are 6 and 2.

Let's assume the first number is x and the second number is y.

From the first statement, we can write the equation x = y + 4.

From the second statement, we can write the equation 2x = 4y + 2.

Now, we can substitute x in terms of y from the first equation into the second equation:

2(y + 4) = 4y + 2

Simplifying this equation, we get:

2y + 8 = 4y + 2

2y = 6

y = 3

Substituting y = 3 in the first equation, we get:

x = y + 4 = 3 + 4 = 7

Therefore, 6 and 2 are the two numbers,

The total bill that Ana would pay is $560.

The total bill that Ana owes is the sum of the first $100 and 10% of the remaining bill since the insurance company would pay 90% of the bill.

The mathematical operation that would be used to determine the total bills are addition, multiplication and subtraction. Addition is the process of determining the sum of two or more numbers. Subtraction is the process of calculating the difference between two or more numbers. Multiplication is the process of determining the product of two or more numbers.

Total bill = first $100 + 90%(total bill - $100)

$100 + 10%($4,700 - $100)

$100 + 10% x 4,600
