An expression which best represents the expression Marie should have used in Step 3 include the following: C. 21/2 × 4/3.

Since Marie had 10 1/2 of ribbon to make bows and each bow required 3/4 of ribbon, the number of bows she could make with the ribbon can be determined by dividing the total number of ribbons by the length required by each bow.

This ultimately implies that, all of the steps that best represents the expression Marie should have used are as follows;

Step 1: 10 1/2 ÷ 3/4

By converting the mixed fraction into an improper fraction, we have the following:

Step 2: 21/2 ÷ 3/4

Rewriting the expression as a function of multiplication, we have the following:

Answer:

Step-by-step explanation:

To solve an algebraic expression in simplest form, you can follow these steps:

1. Use the order of operations (PEMDAS) to simplify any arithmetic in the expression (parentheses, exponents, multiplication and division, addition and subtraction).

2. Combine like terms by adding or subtracting any coefficients in front of similar variables.

3. Divide or multiply both sides of the equation by the same non-zero number to solve for the variable.

4. If possible, factor the expression to make it simpler.

5. If the expression is a fraction, check for a common denominator and then simplify by canceling any common factors in the numerator and denominator.

6. If the expression is a radical, check for a perfect square and simplify by taking the square root of the number inside the radical.

7. Use the properties of exponents and logarithms to simplify the expression.

8. Evaluate the expression by plugging in the values of any known variables.

It's important to keep in mind that there may be multiple ways to simplify an algebraic expression and the solution that is in simplest form may not always be obvious.

Using exponents, 3√78 can be written as (3^(1/3))(78^(1/3))^3.

An exponent is a mathematical notation that represents the number of times a number, called the base, is multiplied by itself. For example, in the expression "2^3", the base is 2 and the exponent is 3. The exponent tells us that we need to multiply the base 2 by itself 3 times, resulting in 222 = 8. So, 2^3 = 8. The exponent is usually written as a small number above and to the right of the base, called the "power" or "index" of the base. Exponents can also be written using the notation "a^n" where a is the base and n is the exponent.

3 √78 can be written as (3^(1/3))*(78^(1/3)) using exponents.

3^(1/3) is the cube root of 3, and 78^(1/3) is the cube root of 78.

So, 3 √78 can be written as (3^(1/3))(78^(1/3)) or (3^(1/3))(78^(1/3))^3.

The quotient of (x^3 + 3x^2 - 4x - 12)/(x^2 + 5x + 6) is (x - 2).

To find the quotient of (x^3+3x^2-4x-12)/(x^2+5x+6) we can use polynomial long division method.

First, divide x^3 by x^2 and write down the quotient (x)

To find the remainder :

(x^3 + 3x^2 - 4x - 12) - x(x^2 + 5x + 6)

= x^3 + 3x^2 - 4x - 12 - x^3 - 5x^2 - 6x

= -2x^2 - 10x - 12

Now divide -2x^2 by x^2 and get the quotient (-2)

Then the remainder is :

(-2x^2 - 10x - 12) - (-2)(x^2 + 5x + 6)

= -2x^2 - 10x - 12 + 2x^2 + 10x + 12

= 0

Answer:

x = 6  and y = 13

Step-by-step explanation:

2x + 2y = 38 ⇒ eq 1

y = x + 7  ⇒ eq 2

Substituting the value of y from eq 2 in 1:

2x + 2(x + 7) = 38

2x + 2x + 14 = 38

4x = 24

x = 24/4

x = 6

Now substituting the value of x in eq 2:

y = ( 6 ) + 7

y = 13

solve the system of equations using substitution

2x+2y=38

y=x+7

Answer:

x= 6, y= 13

Survey results may be impacted by response bias, sampling bias, question bias, mode of administration, and data collection method.

What is factor ?

A factor is a quantity or element that contributes to a particular result or outcome.

There are several factors that may have contributed to the different results of the two surveys:

Response Bias: The online survey may have attracted participants who are more tech-savvy and have a different perspective than those who are less comfortable with technology. On the other hand, the telephone survey may have attracted participants who are older or less mobile, and have a different perspective than those who prefer online communication.

Sampling Bias: The online survey may not have been representative of the entire population, as it was conducted on a specific website and only attracted those who use that website. Similarly, the telephone survey may have only reached those who answered the phone and were willing to participate.

Question Bias: The questions asked in the online survey may have been different from those asked in the telephone survey, leading to different results. The questions may have been worded in a way that biased the responses, either consciously or unconsciously.

Mode of Administration: The mode of administration, or the method of conducting the survey, may have influenced the responses. Online surveys allow participants to respond at their own pace and in their own environment, while telephone surveys may put pressure on participants to respond quickly and may not allow them to think through their responses.

Data Collection Method: The data collection method, such as self-reported data, may have influenced the results. Self-reported data may not always be accurate, as participants may not remember details accurately or may be unwilling to report certain information.

Answer: The domain of the function f is [-1,1], meaning that the input values (x) can be any value between -1 and 1, inclusive of -1 and 1.

The function f(-1) = f(0) = f(1) = 0, meaning that the output value (y) is 0 when the input value (x) is -1, 0 or 1.

The limit of f(x) as x approaches -1,0 and 1 is 1. This means that as x gets closer and closer to -1, 0 and 1, the output value (y) approaches 1.

A possible graph of a function with these properties is a function that has a horizontal asymptote at y=1, and intersects the x-axis at -1, 0, and 1. It means that the function approaches y =1 as x gets closer to -1, 0, and 1 but never reach the point. Also, the function is zero at -1, 0, and 1.

This function is called the absolute value function, and it can be represented by f(x) = |x|.

The length of the square change by a factor of √3.

Let x be the initial side length of the square. The area of a square is equal to the length of one of its sides squared.

A = x²

If the area of a square were to triple in size, it means that the new area of the square has increased by a factor of 3.

initial Area x 3 = new Area

3x² = new Area

Let X be the side length of the new square. Hence, the area of the new square is X squared.

new Area = X² = 3x²

X = √3x²

X = x(√3)

Therefore, the length of the square increased by a factor of √3.

When a system of two linear equations in two variables has no solution, it means that there is no point of intersection between the two lines represented by the equations. This means that the lines are parallel, and do not intersect at any point. This is also known as an inconsistent system. On the other hand, if the two lines intersect at exactly one point, it is a consistent system and has a unique solution. If the two lines are coincident, it will have infinitely many solutions.

A Cartesian plane is defined by two perpendicular number lines: the x-axis, which is horizontal, and the y-axis, which is vertical.

It is named after the French mathematician Rene Descartes, who formalized its application in mathematics.

Any point in the plane can be described by an ordered pair of numbers using these axes.

So, we have the points:

(3,2) and (2,3)

Point P's coordinates are 3 for the x-coordinate and 2 for the y-coordinate.

Point Q's coordinates are 2 for the x-coordinate and 3 for the y-coordinate.

The point is not the same because the coordinates of the two are different.

The value of an account can be calculated using the formula for continuously compounded exponential growth given by A = P[tex]e^{rt}[/tex], where A is the final amount, P is the initial amount, r is the interest rate and t is the time.

A proportion of a sum of money is charged as interest for using it. Usually, it is stated as an annual percentage rate (APR). Interest rates can vary based on the kind of loan, the lender, and the borrower's creditworthiness. They are commonly charged on loans, credit cards, and savings accounts.

In the given question, the value of the account can be calculated using the formula for continuously compounded exponential growth given by A = Pe^rt, where A is the final amount, P is the initial amount, r is the interest rate, and t is the time.

Substituting the given values, we get:

$1,360 = $700[tex]e^{(0.049t)}[/tex]

To solve for t, we can take the natural logarithm of both sides:

ln(1360) = ln(700) + 0.049t

Rearranging and solving for t, we get:

t = (ln(1360) - ln(700))/0.049

t = 9.68 years

Rounding to the nearest year, it would take 10 years for the value of the account to reach $1,360.

You can determine if three variables are linear if their graph forms a straight line when plotted. Additionally, the relationship between the variables should follow a linear equation.

Linearity between three variables can be determined by examining their relationship. If the variables are linearly related, then plotting them on a graph will result in a straight line. Additionally, the relationship between the variables should follow a linear equation, which is a form of an equation where each term is either a constant or the product of a constant and a single variable. To determine if a given equation is linear, you can examine its terms to see if they are all either constants or the product of a constant and the variable. If a variable is raised to a power other than 1, the equation is not linear. In short, if the graph of the three variables forms a straight line and the equation between them is linear, then the variables are linear.
