The absolute value of a number is the distance of that number from 0 on the number line. Since 5 and -5 are both 5 units away from 0, the absolute value of both numbers is 5. Therefore, |5| = |-5| = 5.

The absolute value of a number is a non-negative value that represents the distance of that number from zero on the number line. It is denoted by two vertical bars "||" surrounding the number. For example, the absolute value of 5 is written as |5|.

For positive numbers, the absolute value is simply the number itself. For example, |5| = 5.

For negative numbers, the absolute value is the numerical value of the number but with the opposite sign. For example, |-5| = 5.

In other words, the absolute value of a number removes any negative sign and gives the distance of the number from 0, regardless of its sign. So, the absolute value of 5 is 5 and the absolute value of -5 is also 5. They are the same distance from 0 on the number line.

Using the provided condition and values, This is solved using the concept of word problem, The answer is Polly gets £30, Andy gets £60 and Phoebe gets £180.

A word problem in mathematics is a problem that is written in natural language (i.e., words) rather than in mathematical notation. It presents a real-world scenario that requires the use of mathematical concepts and skills to solve. Word problems often involve finding unknown quantities based on given information, and they can be challenging because they require students to understand the problem and translate it into mathematical equations or formulas. They are often used in primary and secondary education to help students apply their math skills to real-world situations and develop critical thinking skills.

A mathematical expression is a combination of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, and division) that represents a mathematical statement or equation. Mathematical expressions can be evaluated to find a numerical value. They can also be simplified by applying the order of operations (PEMDAS) to combine like terms or to remove unnecessary parentheses. Additionally, mathematical expressions can also be used to represent the relationship between different variables.

Let x be the amount that Polly gets.

Andy would get 2x and Phoebe would get 3(2x) = 6x

So the total amount would be x + 2x + 6x = 9x

Therefore, x + 2x + 6x = £270

9x = £270

x = £30

So Polly gets £30, Andy gets £60 and Phoebe gets £180.

To find this, we can apply the equation distance = rate x time.

We are aware of the length and pace of each triathlon leg. Let's name them, respectively, d and r. We must locate the time, which we shall designate as t.

d = r x t    or

t = d/r

The distance is 0.93, or 93/100, and the rate is 1.2, or 12/10 when swimming. As a result of our formula, we have:

12/10 divided by 93/100 yields the same result as

93/100 * 10/12

time to swim = 93/120 = 31/40

We have a distance of 24.8 miles, or 248/10, and a speed of 18.8 miles, or 188/10, for biking. Using the same formula, we obtain:

248/10 divided by 188/10 or

248/10 * 10/188 = 248/188 = 62/47 = time to bike

Finally, for the run, the distance is 6.2 = 62/10 and the rate is 5.1 or 51/10. Plugging this into the formula gives:

62/10 divided by 51/10 or

62/10 * 10/51 = 62/51 = time to run

There is no regular polygon that satisfies the given condition.

What is a regular polygon?

A polygon is called regular if it has equal sides and angles. Thus, a regular triangle is an equilateral triangle, and a regular quadrilateral is a square.

Let n be the number of sides in the polygon.

The interior angle of a regular polygon with n sides is (n-2) * 180/n degrees.

The exterior angle of a regular polygon with n sides is 360/n degrees.

We are given that:

(n-2) * 180/n > 3 * 360/n + 20

Simplifying the equation:

(n-2) * 180 > 3 * 360 + 20 * n

Now we can solve for n.

(n-2) * 180 > 1080 + 20n

180n - 360 > 1080 + 20n

-20n > 720

n < -36

The correct option is option a) Yes, this is plausible for the population mean because the upper boundary of the 95% confidence interval is below 7 minutes.

A confidence interval is a range of values, derived from a sample of data, that is used to estimate an unknown population parameter. The interval has an associated confidence level, such as 90%, 95%, or 99%, which indicates the level of confidence that the interval contains the true population parameter.

The most commonly used method to calculate a confidence interval is the method of maximum likelihood estimation. The wider the interval, the less certain the estimate, and the narrower the interval, the more certain the estimate.

It is plausible that the true mean number of times for all mice to complete the maze may be less than 7 minutes, as the interval provided by the researcher (2.9 minutes to 6.83 minutes) does not include 7 minutes as an upper bound.

A 95% confidence interval indicates that if the study were to be repeated multiple times, 95% of the intervals created would contain the true mean, so there is a 5% chance that the true mean falls outside of the interval provided.

Therefore, The correct option is option a) Yes, this is plausible for the population mean because the upper boundary of the 95% confidence interval is below 7 minutes.

The number 10 is typically found at latitudes above the Arctic Circle (about 66.5 degrees North) during the summer solstice, the longest day of the year.

During the summer solstice, the tilt of the Earth's axis is such that the North Pole is tilted towards the sun, providing more direct sunlight to areas within the Arctic Circle. This results in several weeks to months of constant daylight, known as the "midnight sun."

The centimeter equivalent of Sadie's height is 142.875 cm.

(63.5×2.25) cm.

= 142.875 cm.

The equation of a line in the form y is y = 150 - 85x.

This equation can be used to determine the amount of money in the grocery account at any given week, x. To solve, we will use the information given in the question.

We know that the initial amount in the account is $150. This is the y-intercept of the line. Therefore, 150 = 150 - 85x. Solving this equation for x, we get x = 0. This means that at week 0 the account has a balance of $150.

Next, we know that money is withdrawn from the account every week. We can use this information to solve for the slope of the line. We know that every week $85 is withdrawn from the account, so the slope of the line is -85. Therefore, the equation of the line is y = 150 - 85x.

Using this equation, we can determine the amount in the account at any given week. For example, at week 5, y = 150 - 85(5) = $25. This means that the account has a balance of $25 at week 5.

The equation of the tangent line at x = 4 is:

y = 179*x  - 490

(your teacher or the person who wrote this problem made a mistake somewhere, as none of the options is near correct)

We have:

f(x) = 4x³ - 2x² + 3x - 10

When x = 4 we have:

f(4) = 4*4³ - 2*4² + 3*4 - 10 = 226

So we want a line tangent to the curve at the point (4, 226)

To find the slope of that line, we need to evaluate the derivative of f(x) in x = 4.

The derivative is:

f'(x) = 3*4x² - 2*2x + 3

f'(x) = 12x² - 4x + 3

Then the slope is:

f'(4) = 12*4² - 4*4 + 3 = 179

Then the tangent line is something like:

y = 179*x + b

To find the value of b, we replace the values of the point (4, 226)

226 = 179*4 + b

226 - 179*4 = b = -490

The line is:

Step-by-step explanation:

Firstly, it is important to rearrange the function in decreasing order. The function will now be f (x) = 4x^9+5x^8+4x^6+9x+1

Secondly, for finding the zeros, it is necessary to find the degree of the function. The maximum number of zeroes in a polynomial is the degree of the function. The degree of a function is the highest value of exponents in the function. Here, in this function, the degree is 9.

Lastly, the degree of the function is the number of zeroes. Since the degree is 9, the number of zeroes possible is also 9.

The answer is 2 metric tons in an hour.

Units refer to a specific measurement or denomination used to express the size or quantity of something. For example, length can be measured in units of inches, feet, or meters. Time can be measured in units of seconds, minutes, or hours.

The best way to do this is to convert all the fractions to decimals. The problem starts out looking like this.

Formula :

Rate = Tons removed / hours

Tons Removed = 1/2 metric ton

Time taken = 1/4 hour

Rather than doing it with fractions, it is much easier to do it with decimals

1/4 = 0.25

1/2 = 0.5

Now what you get is rate = 0.5 / 0.25 = 2

So, 2 metric tons can be removed in an hour.
