There will be twelve and a half city blocks of the street sweepers clean on Tuesday.

The numerator, which is found at the top of the fraction number, and the denominator, which is located at the bottom, are its two component components.

It is given that, four city blocks were cleaned by a crew of street sweepers on Monday. The crew cleaned 2 1/6 as many blocks on Tuesday as they did on Monday.

Suppose the number of city blocks the street sweepers cleaned on Tuesday will be x,

x = 4 +  2 1/6 × 4

x=4+13/6×4

x=12.6≈ 12 1/2

Thus, the street sweepers will clean twelve and a half city blocks on Tuesday.

Answer:

94 million

Step-by-step explanation:

6 million is the 6% of 100 million

If the unemployment rate is 6%, then 94% of the population is employed.

94% of 100 million is 94 million.

The required number of employed people is 94 million.

Given that,
The unemployment rate is 6 percent and the number of persons unemployed is 6 million, then the number of people employed is equal is to be determined.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Let the total sum of the people employed and unemployed be x,
According to the question,
6 % of x = 6 million,
x = 6 / 0.06
x = 100 million,
Now,
Number of employed people = 100 - 6 = 94 million people

Thus, the required number of employed people is 94 million.

Answer:

$1,116.19.

Step-by-step explanation:

Given that artificial grass sells for $ 10.98 per square yard, to determine the final cost to buy and install 69.2 square yards if the seller charges $ 5.15 per square yard for labor, round to the nearest cent, the following calculation must be performed:

69.2 x (10.98 + 5.15) = X

69.2 x 16.13 = X

1,116,196 = X

Thus, the cost to purchase and install 69.2 square yards of artificial grass is $ 1,116.19.

Answer:

d. The bias will remain the same and the variance will increase.

Step-by-step explanation:

Sample size and bias:

800 is still a large sample size, so the bias will remain the same.

Variance:

From a data set of size n with mean M, the variance is given by:

\(V = \sum_{i=0}^{n} \frac{(x_i - M)^2}{n}\)

So as we decrease the sample size, variance increases.

So the correct answer is given by option d.

They do have the following relation for a random selection of n elements from a population with a mean of p and variation \(\sigma^2\).

         \(\to \mathbb{E} (\bar{x}) = \mu;\\\\\to Var(\bar{x}) = \frac{\sigma^2}{n}\)    (where \(\bar{x}\) is the sample mean)

Therefore, the answer is "Option C".

The area of the smaller rectangle (KLMN) is 16.

Since rectangles ABCD and KLMN are similar, their corresponding sides are proportional.

Let's assume the length of side AB in rectangle ABCD is x, and the length of side KL in rectangle KLMN is y.

We can set up the proportion:

(x/y) = (20/16)

To find the area of the smaller rectangle, we need to determine the ratio of their areas.

Since the area of a rectangle is given by the product of its length and width, the ratio of the areas will be equal to the square of the ratio of their sides:

(Area of ABCD)/(Area of KLMN) = (x²)/(y²)

We are given that the area of ABCD is 25, so we have:

25/(Area of KLMN) = (x²)/(y²)

To find the area of KLMN, we need to substitute the values of x and y from the proportion:

25/(Area of KLMN) = (20/16)²

Simplifying the right side:

25/(Area of KLMN) = (5/4)²

25/(Area of KLMN) = 25/16

Cross-multiplying:

25 × 16 = 25 × (Area of KLMN)

400 = 25 × (Area of KLMN)

Dividing both sides by 25:

16 = Area of KLMN

Therefore, the area of the smaller rectangle (KLMN) is 16.

Answer:

Step-by-step explanation:

Given function is, \(f(x)=\frac{x^2-3x+2}{x-2}\)

Factors of the numerator = x² - 3x + 2

                                          = x² - 2x - x + 2

                                          = x(x - 2) - 1(x - 2)

                                          = (x - 2)(x - 1)

Therefore, given function will be,

f(x) = \(\frac{(x-2)(x-1)}{(x-2)}\)

For (x - 2) = 0

For x = 2, denominator will become zero.

Thus for input value x = 2, function will not be defined.

If x ≠ 2, f(x) = x - 1

It's a linear function represented by f(x) = x - 1

We have proven that if A and B are m x n matrices, then A and B are row equivalent if and only if A and B have the same reduced row echelon form.

Matrices are a type of mathematical structure used to store and analyze data. They are represented as a series of rows and columns, with each cell in the matrix containing a number or other value. Matrices are used to solve systems of equations, perform matrix multiplication and determine the inverse of a matrix. They are also used in linear programming, cryptography, and other areas of mathematics.

Row equivalence is defined as a pair of matrices A and B being row equivalent if there is a sequence of row operations that can transform A into B, or vice versa. This means that if A and B are row equivalent, then A and B can be transformed into one another by a series of row operations.

A reduced row echelon form is defined as a matrix in which all non-zero rows are above any rows of all zeroes and the leading coefficient of each non-zero row is 1. In other words, all of the non-zero rows have a leading coefficient of 1, and any rows of all zeroes are below the non-zero rows.

Therefore, if A and B are row equivalent, then A and B can be transformed into one another by a series of row operations. This means that we can use the same series of row operations to transform A and B into the same reduced row echelon form. This proves that if A and B are row equivalent, then A and B have the same reduced row echelon form.

On the other hand, if A and B have the same reduced row echelon form, then they must have been transformed into the same form by a series of row operations. This means that the same series of row operations must have been used to transform A and B into the same reduced row echelon form, which means that A and B are row equivalent. This proves that if A and B have the same reduced row echelon form, then A and B are row equivalent.
To prove that if A and B are m x n matrices, then A and B are row equivalent if and only if A and B have the same reduced row echelon form, we can use the definition of row equivalence and the definition of a reduced row echelon form.


Therefore, we have proven that if A and B are m x n matrices, then A and B are row equivalent if and only if A and B have the same reduced row echelon form.

If the number of products within specifications is less than 8 out of 12, the outcome would be considered unusual and the production line should be repaired.

Since 79% of the products come off the line ready to ship, the probability of any one product being within specifications is 0.79. Using the binomial distribution, we can calculate the probability of getting less than 8 products within specifications out of 12 by summing the probabilities of getting 0, 1, 2, ..., 7 products within specifications:

Using the binomial probability formula, we can calculate each of these probabilities:

where "k" represents the number of products within specifications.

Using a calculator or software, we can find that the probability of getting less than 8 products within specifications is approximately 0.015. This probability is considered small, and therefore, the outcome would be considered unusual. If this occurs, the production line should be repaired to improve the quality of the products.
