Using the arithmetic operations it is obtained that Russell ran 4 miles through his neighborhood every day after school.

To solve this problem, we can use the following equation -

total distance = distance per day x number of days

We know that Russell ran 2 miles around the football field before school every day.

Using multiplication,

Therefore, his total distance for the week from running around the football field is -

2 miles/day × 5 days = 10 miles

We also know that Russell ran a longer route through his neighborhood after school every day.

Let's call the distance of this route "x" miles.

Russell ran this route 5 times during the week, so his total distance from running through his neighborhood is -

Use multiplication,

x miles/day × 5 days = 5x miles

Finally, we know that Russell's total distance for the week was 30 miles. We can set up the equation -

Use addition,

10 miles + 5x miles = 30 miles

Simplifying, we get -

5x miles = 20 miles

x = 4 miles

Therefore, the distance value is obtained as 4 miles.

Sarah fell behind 3 meters each lap.

What is Total distance?

Whole distance refers to the actual travel distance between the origin and destination locations of the item.

If Sarah was 15 meters behind Anna when Anna finished the race, and they both ran the same distance, we can divide the total distance by the number of laps they ran to find the distance they ran per lap:

Total distance = 5 laps

Distance per lap = total distance / number of laps = 5 laps / 1 = 5

So Sarah and Anna each ran 5 meters per lap. If Sarah fell behind the same number of meters during each lap, we can use a negative integer to describe the distance she fell behind each lap. The distance she fell behind each lap is:

-3 meters (since 3 meters + 3 meters + 3 meters + 3 meters + 3 meters = 15 meters, which is the distance by which she was behind when Anna finished the race).

Therefore, Sarah fell behind 3 meters each lap.

Therefore, the prime trinomials are: 5x² + 4x + 4 and 5x² – 8x + 2.

A polynomial is a mathematical expression that consists of variables, coefficients, and exponents, combined using the operations of addition, subtraction, and multiplication. Polynomials are widely used in mathematics and other fields to model a wide range of phenomena and processes. In a polynomial, the variables are usually represented by letters such as x, y, or z, while the coefficients are numbers that multiply the variables. The exponents indicate the power to which each variable is raised.

Here,

To determine which trinomials are prime, we need to factor each trinomial and check if it can be factored further into linear factors with integer coefficients. If a trinomial can be factored further, then it is not prime. On the other hand, if a trinomial cannot be factored further, then it is prime.

Let's factor each trinomial and see which ones are prime:

x² + 11x + 18

This trinomial can be factored into (x + 2)(x + 9), so it is not prime.

x²  + 11x + 18

This trinomial can be factored into (x + 2)(x + 9), so it is not prime.

x² – 3x – 2

This trinomial can be factored into (x – 2)(x + 1), so it is not prime.

x²  – 3x – 2

This trinomial can be factored into (x – 2)(x + 1), so it is not prime.

In the given situation, one snack bar has 14 carbohydrates.

Let's denote the number of carbs in one snack bar as "x".

From the given information, we can set up a system of two equations:

2x + 3y = 73 (where y is the number of carbs in one glass of milk)

4x + 2y = 86

We can then solve for x by using elimination or substitution.

Using elimination, we can multiply the first equation by 2 and subtract it from the second equation:

4x + 2y = 86

(4x + 6y = 146) (2 times the first equation)

-4y = -60

Dividing both sides by -4, we get:

y = 15

Substituting this value of y into the first equation, we can solve for x:

2x + 3y = 73

2x + 3(15) = 73

2x + 45 = 73

2x = 28

x = 14

Therefore, there are 14 carbs in one snack bar.

Step-by-step explanation:

Let's start by defining some variables to represent the unknowns in the problem:

Let x be the number of carbohydrates in one snack bar.

Now, we can use the given information to set up a system of equations:

2x + 3y = 73 (where y is the number of carbohydrates in one glass of milk)

2y + 4x = 86

We have two equations and two unknowns, so we can solve for x and y using any method we prefer. Here, we will use the substitution method:

Rearrange the first equation to solve for y: y = (73 - 2x)/3

Substitute this expression for y in the second equation: 2((73 - 2x)/3) + 4x = 86

Simplify: (146 - 4x)/3 + 4x = 86

Multiply both sides by 3 to eliminate the fraction: 146 - 4x + 12x = 258

Simplify: 8x = 112

Solve for x: x = 14

The true proportion of all adults in the United States who exercise on a regular basis is between 0.384 and 0.493 with 90% confidence interval.

To construct a confidence interval for the proportion of all adults in the United States who exercise on a regular basis, we can use the formula:

CI = p ± z√(p(1-p)/n)

where:

p = proportion of the sample who exercise on a regular basis

n = sample size

z = z-score from the standard normal distribution corresponding to the desired level of confidence

Here, p = 82/187 = 0.4385 and n = 187.

A standard normal distribution table or calculator, or use the following formula:

z = invNorm((1 + C)/2)

where:

C = confidence level (expressed as a decimal)

invNorm() = inverse normal distribution function

For a 90% confidence level, C = 0.90, so:

z = invNorm((1 + 0.90)/2) = invNorm(0.95) ≈ 1.645

Substituting in the values, we get:

CI = 0.4385 ± 1.645√(0.4385(1-0.4385)/187) ≈ 0.384, 0.493

Therefore, we can say with 90% confidence that the true proportion of all adults in the United States who exercise on a regular basis is between 0.384 and 0.493, rounded to three decimal places.

The translation that occurred to the segment is: B. The segment was shifted to the right four units and up five units.

Translation is a transformation in which an object is moved without being rotated, resized or distorted. It involves sliding the object a certain distance in a certain direction, while maintaining its shape and size. The resulting image of the object is congruent to the original object, meaning that they have the same size and shape.

To find the translation that occurred to the segment, we need to calculate the distance between point A and its image A' and the direction in which the translation occurred.

The distance between A and A' is given by:

√((7-3)² + (2-(-3))²) = √(16 + 25) = √(41)

So the segment was translated by a distance of √(41).

To find the direction of the translation, we can subtract the coordinates of A from the coordinates of A':

(A'x - Ax, A'y - Ay) = (7-3, 2-(-3)) = (4, 5)

So the segment was shifted to the right four units and up five units.

Therefore, the correct answer is B. The segment was shifted to the right four units and up five units.

As a result, after five years, the business makes $102.10 per hour of work performed by men.

The gains that a company makes are its earnings. They are obtained by deducting revenue from cost of products sold, running costs, and taxes. The creation and ongoing running of a company are primarily motivated by the desire to generate profits. Dividend payments to stockholders can then be made with the earnings.

If the factory earned $80 per man-hour of labor when it opened, and each year earns an additional 5% per man-hour, we can calculate the earnings for any given year using the formula:

E = $80 × (1 + r)ⁿ

where E is the earnings per man-hour, r is the annual rate of increase (5% = 0.05), and n is the number of years since the factory opened.

For example, if we want to find the earnings per man-hour after 3 years, we would plug in n=3:

E = $80 × (1 + 0.05)³

E = $80 × 1.157625

E = $92.61

Therefore, after 3 years, the factory earns $92.61 per man-hour of labor.

Similarly, if we want to find the earnings per man-hour after 5 years, we would plug in n=5:

E = $80 × (1 + 0.05)⁵

Hence, It is on every 100 students, 59 students prefer coffee over tea.

Thus, The first statement is 590 students must prefer coffee to tea is true.

And, Second statement is Less than 590 students must prefer coffee to tea is false .

And, The third statement is More than 590 students must prefer coffee to tea is also false.

And, The fourth statement is,

In which the variables used to calculated these bounds are listed as follows:

The confidence level is of 99%, hence the critical value z is the value of Z that has a p-value of 0.995, so the critical value is z = 2.575.

The correct answer is f(m)=5230(1.015)m12.

A function is a self-contained block of code that takes inputs, performs specific operations on those inputs, and produces an output. It is a subprogram that performs a specific task, and helps to break down larger programs into smaller, more manageable pieces. Functions are also reusable, meaning that once a function is written, it can be used over and over again in different places in the program.

This function can be used to represent the student enrollment m months after the study began, as it takes into consideration the number of years (t) represented by the number of months (m) and incorporates it into the equation. The equation multiplies the number of months (m) by 12 to convert it into the number of years (t) used in the original equation, f(t)=5230(1.015)t. This ensures that the correct student enrollment is calculated based on the number of months since the study began.
