The chart which is most relevant representation for Anthony's purposes is;

b. A graph has year on the x-axis, from 2001 to 2005, and value (dollars per share) on the y-axis, from 80 to 200 in increments of 40. A curve goes through (0, 170), (2003, 90), (2005, 130)

Step-by-step explanation:

From the question, we have;

The time at which Anthony was preparing to purchase shares = January, 2005

The number of shares Anthony was preparing to purchase = 100 shares

The information he found in the literature = Charts on ABC stock performance

The information required = The current price of shares of ABC stock

Therefore, the chart that is most relevant is a chart that gives the 2005 pricing  of ABC stock which is the graph that has a curve that goes through (0, 170), (2003, 90), (2005, 130)

An essential concept in mathematics and can be applied to a variety of fields such as physics, economics, and engineering.

The slope of a line in a Cartesian plane is a numerical representation of its steepness and inclination relative to the x-axis.

The slope of a straight line refers to the rise or fall of the y-coordinate as it moves from left to right along the x-axis.

There are a few different ways to interpret the slope of a line, but generally it can be thought of as the rate at which the dependent variable changes with respect to the independent variable.
When the slope is positive, the line rises from left to right, indicating that the dependent variable is increasing as the independent variable increases.

In other words, there is a direct relationship between the two variables.

Conversely, when the slope is negative, the line falls from left to right, indicating that the dependent variable is decreasing as the independent variable increases.

This means that there is an inverse relationship between the two variables.
The magnitude of the slope can also provide information about the relationship between the variables.

If the slope is close to zero, then the relationship between the two variables is weak or nonexistent.

However, if the slope is large in magnitude (i.e. close to 1 or -1), then there is a strong relationship between the variables.

A slope of zero indicates that there is no change in the dependent variable as the independent variable changes, while a slope of undefined means that the line is vertical and has no slope.

Step-by-step explanation:

The statement which best describes the function F(x)=2x^2-3x+1 is it is a many to one function.

A piecewise function is a function built from pieces of different functions over different intervals. For example, we can make a piecewise function f(x) where f(x) = -9 when -9 < x ≤ -5, f(x) = 6 when -5 < x ≤ -1, and f(x) = -7 when -1 <x ≤ 9.

f(x) = x2 shows us that function "f" takes "x" and squares it. Example: with f(x) = x2: an input of 4. becomes an output of 16.

The resulting equation would be AD = BC. Therefore, to calculate the proportion, you need to multiply the numerator of one ratio by the denominator of the other ratio and equate the products.

What are proportions? Proportions are two ratios that are equivalent or equal to each other. The ratios can be represented as a fraction or a decimal. Proportions are useful in math when dealing with solving problems that involve ratios or comparisons between two values or quantities. How to calculate proportions? To calculate a proportion, you need to compare two ratios. For instance, if you have two ratios A:B and C:D, the proportion will be A:B = C:D. It implies that A is to B as C is to D. Then you can cross-multiply the proportion, which means multiplying the numerator on the left by the denominator on the right, and then multiplying the numerator on the right by the denominator on the left.  The proportions that are most useful in analysing the relationship between passenger class and surviving the Titanic are 203/325 and 178/706. The resulting equation would be AD = BC. Therefore, to calculate the proportion, you need to multiply the numerator of one ratio by the denominator of the other ratio and equate the products.

The standard deviation of the costs is 37 Dhs

The given mean is 173 and 3% of costs exceed 243. We have to calculate the standard deviation of the cost. Therefore, let's first start by calculating the z-score as follows;z-score formula = `(x - μ) / σ`z-score = `243 - 173 / σ`z-score = `70 / σ`We need to find the standard deviation of the costs. Since the z-score formula includes standard deviation, we can first calculate the z-score and then use it to calculate the standard deviation.Using the z-table, we can find the z-score for 3% = -1.88-1.88 = (243 - 173) / σσ = (243 - 173) / -1.88σ = -70 / -1.88σ = 37.23≈ 37The standard deviation of the costs is 37 Dhs. Hence, the correct option is as follows.Option D is the correct option.

The 95% confidence interval for the difference between the two population proportions is -0.022 < p₁ - p₂ < 0.222.

Given that,

In a survey, it was discovered that 68% of women and 78% of men preferred computer-assisted education to lectures, respectively. Each sample contained 100 people that were chosen at random.

We have to calculate the 95% confidence range for the difference between the two proportions.

We know that,

The 95% confidence interval for difference between two population proportions is given as follows :

\(((\bar p_{1} -\bar p_{2})\)±\(Z_{0.05/2}\sqrt{\frac{PQ}{n_{1} } +\frac{PQ}{n_{2} }} })\)

Here,

p₁ is 0.78

p₂ is 0.68

n₁ is 100

n₂ is 100

Z is 1.96

P is 0.73

Q is 0.27

So,

((0.78-0.68)±\(1.96\sqrt{\frac{(0.73)(0.27)}{100 } +\frac{(0.73)(0.27)}{100 }} })\)

(0.10±0.122)

(0.10-0.122,0.10+0.122)

(-0.022,0.222)

Therefore, The 95% confidence interval for the difference between the two population proportions is -0.022 < p₁ - p₂ < 0.222.

If the matrix is said to be in reduced echelon form then it should satisfy the following conditions:

1. The pivot in any non-zero row is the only non-zero entry in its column.

2. The pivot in any non-zero row is positive.

What is an echelon form?

A matrix in reduced echelon form is also sometimes referred to as a row-reduced echelon form or simply a reduced row echelon form (RREF). To check if a matrix is in RREF, you need to verify if the matrix satisfies both the conditions for echelon form and the additional conditions for RREF.

1. A matrix is said to be in echelon form if it satisfies the following conditions:

2. All zero rows (if any) are at the bottom of the matrix.

3. The leading entry (the first non-zero entry) of each non-zero row occurs to the right of the leading entry of the previous row.

4. The leading entry in any non-zero row is 1, called a pivot.

A matrix is said to be in reduced echelon form if it is in echelon form and additionally satisfies the following conditions:

1. The pivot in any non-zero row is the only non-zero entry in its column.

2. The pivot in any non-zero row is positive.

Hence, if the matrix is said to be in reduced echelon form then it should satisfy the following conditions:

1. The pivot in any non-zero row is the only non-zero entry in its column.

2. The pivot in any non-zero row is positive.
