Therefore, Linda bought 21 yards of ribbon. Hence, Linda bought 94 yards of ribbon.

The number of yards of ribbon Linda bought, we need to calculate the difference between the initial balance on the card and the remaining balance after the purchase.

The initial balance on the card was $20. To find the amount spent on ribbon, we subtract the remaining balance ($17.06) from the initial balance. $20 - $17.06 = $2.94

Now, we need to determine how many yards of ribbon Linda could purchase with $2.94, given that the price of the ribbon is 14 cents per yard.

To find the number of yards, we divide the total amount spent ($2.94) by the price per yard (14 cents): $2.94 ÷ $0.14 = 21

Therefore, Linda bought 21 yards of ribbon.

Hence, Linda bought 94 yards of ribbon.

The number of ways is 1 billion.

We are asked to determine the possible number of ways of the social security number that is 9 digits if the numbers can be repeated.

In this case, using fundamental counting, there are 10 possible numbers in each digit that is from zero to nine.

Thus, the number of ways is 10*10*10*10*10*10*10*10*10 equal to 1 billion ways.

A stretch of an exponential growth function is one that contains a constant factor that affects the rate of growth. Of the three functions given, only O fx) = 2^312 meets this criteria.

To determine which of these functions is a stretch of an exponential growth function, we need to look for the presence of a constant factor or coefficient that affects the rate of growth. In the first function, Of(x) = 22(x)3, we see that there is no constant factor present. The base of the exponential function is simply 2, which means that the rate of growth is constant and does not change.
Similarly, in the second function, Of(x) = 3, there is no exponential term present, and therefore no growth or decay is occurring. This function simply returns a constant value of 3 for any input value of x.
In the third function, Of(x) = 2^312, we see that there is a constant factor present in the base of the exponential function. This means that the rate of growth is being affected by this factor, resulting in a steeper curve than the first two functions. Therefore, O fx) = 2^312 is a stretch of an exponential growth function.

The correct expression for an exponential growth function with a stretch is Of(x) = 2^12x.

The correct expression for an exponential growth function is Of(x) = 212x.

This is because the exponent, 12x, represents the rate at which the function is growing.

A larger value for the exponent results in a steeper growth rate, which indicates a stretch of the exponential growth function.

Approximately 4.99% of Americans are diagnosed with diabetes at the age of 45.

a. Rewrite the equation as a function:
The given equation is y = 0.42x - 13.91. To rewrite it as a function, we can use the notation f(x) instead of y. So, the function is:

f(x) = 0.42x - 13.91

b. What is the y-intercept? What does it mean in this situation?
The y-intercept is the point where the function crosses the y-axis. In this equation, it occurs when x = 0. To find the y-intercept, substitute x = 0 into the function:

f(0) = 0.42(0) - 13.91
f(0) = -13.91

The y-intercept is -13.91. In this situation, it represents the percentage of Americans diagnosed with diabetes at the age of 0. Since this value is negative, it doesn't have a real-life meaning in this context, as the percentage cannot be negative.

c. Find S(45). What does it mean in this situation?
To find S(45), substitute x = 45 into the function:

f(45) = 0.42(45) - 13.91
f(45) = 18.9 - 13.91
f(45) ≈ 4.99 (rounded to two decimal places)

S(45) is approximately 4.99. In this situation, it means that approximately 4.99% of Americans are diagnosed with diabetes at the age of 45.

Step-by-step explanation:

The given fractions have equal value, so Liam is correct.

Equivalent fractions are defined as fractions that have different numerators and denominators but the same value. For example, 2/4 and 3/6 are equivalent fractions because they are both equal to 1/2. A fraction is part of a whole. Equivalent fractions represent the same part of a whole.  

Liam is claiming that the fraction -(5/12) is equivalent to 5/-12.

Thus, we can say that:

The fraction  -(5/12) can be described as the opposite of a positive number divided by a positive number. A positive number divided by a positive number always results in a positive quotient and its' opposite is always negative.

The fraction 5/-12 can be described as a positive number divided by a negative number which always results in a negative quotient

We will have the following:

***Explanation***

We have that absolute value is used in order to obtain magnitudes, and since magnitudes are positive those are the values we are going to obtain.

Now, for example:

|5| = 5

|-5| = 5

|420| = 420

|-69| = 69

|342| = 342

|-23| = 23

This is the nature of the absolute value, it gives us the positive value and thus the magnitude (In other words it removes the "direction" the value had.)

Answer: 1.25 or 5/3.

Step-by-step explanation: Multiply 1 and 4 to get 4. Add 4 and 3 to get 7. 3− 7/4. Convert 3 to fraction 12/4. Since 12/4 and 7/4 have the same denominator, subtract them by subtracting their numerators. Subtract 7 from 12 to get 5. 5/4 or 1.25.

3-(1/3 4) doesn't really make sense so I went with 3-(1 3/4). 1.25 is the best answer.

Answer:

(b) m<4 = 77 degrees.

Step-by-step explanation:

A: The sum of the measures of all three interior angles in a triangle always is 180 degrees. Knowing this, we add the two known interior angles, 20 and 57, then subtract that from 180 to get 103 degrees.

B: The measure of an exterior angle is the sum of the two opposite interior angles. So, we add 57 and 20 to get the m<4 = 77 degrees.

Solving for q will give us the optimal quantity that maximizes the profit,  a function that gives the total profit earned can be written as:

Profit(q) = (Revenue per item - Cost per item) * q

Assuming that the revenue and cost are functions of the quantity sold (q), the total profit can be calculated as follows:

Profit(q) = Revenue(q) - Cost(q)

To find the quantity which maximizes the profit, we can take the derivative of the profit function with respect to q and set it equal to zero, and then solve for q:

Profit'(q) = Revenue'(q) - Cost'(q) = 0

Solving for q will give us the quantity that maximizes the profit. However, without knowing the specific forms of the revenue and cost functions, we cannot write a specific profit function or find the quantity that maximizes the profit.

In general, the profit function can be written as:

Profit(q) = (Revenue per item - Cost per item) * q

where the revenue per item and cost per item are functions of q. To find the quantity that maximizes the profit, we need to differentiate the profit function with respect to q and set it equal to zero:

Profit'(q) = Revenue'(q) - Cost'(q) = 0

Solving for q will give us the optimal quantity that maximizes the profit.

Based on the given information, we know that x must be 2 since it is the only even prime number. We also know that y must be either 11, 13, 17, or 19 since those are the only prime numbers between 10 and 20.

So, the sum of x and y can be 2 + 11 = 13, 2 + 13 = 15, 2 + 17 = 19, or 2 + 19 = 21.

Out of these four possible sums, only 13, 17, and 19 are prime numbers. Therefore, we can say that the sum of x and y may or may not be a prime number, depending on the specific values of x and y.

The chain rule states that if we have a differentiable function z = f(x, y), where x = s(t) and y = p(t) are functions of one variable, then \(\(\frac{dz}{dt}\)\) can be computed using the following formula: \(\[\frac{dz}{dt} = \frac{\partial f}{\partial x} \cdot \frac{dx}{dt} + \frac{\partial f}{\partial y} \cdot \frac{dy}{dt}\]\)

The chain rule allows us to find the rate of change of a function with respect to time when the function depends on multiple variables. It states that the derivative of a composite function is the product of the derivative of the outer function with respect to the inner function, and the derivative of the inner function with respect to the independent variable.

In the given context, the variable t represents the independent variable, and we want to find the derivative \(\(\frac{dz}{dt}\)\), which represents the rate of change of z with respect to time. By applying the chain rule, we can break down the problem into smaller parts. We first compute the partial derivatives of f with respect to x and y, and then multiply them with the derivatives of x and y with respect to t, respectively. Finally, we sum up the two products to obtain the derivative \(\(\frac{dz}{dt}\)\) of the composite function z = f(x, y) with respect to t.

The null hypothesis should assert that the average work week has not been significantly reduced, which is the opposite of the alternative. This can be expressed mathematically as 40.1 as the genuine mean.
