By using this absolute value equation, the chef can determine the range of cake diameters that meet the desired margin of error of 3 inches and make an informed decision when purchasing the cake.

The absolute value of the difference between the actual diameter of the cake and the ideal diameter of 24 inches should be less than or equal to 3 inches.

To describe the statement using an absolute value equation, let's define the variable "d" as the actual diameter of the cake.

The ideal diameter of the cake is given as 24 inches.

The margin of error is specified as 3 inches, which means the chef is willing to accept a cake with a diameter within 3 inches of the ideal size.

Considering the margin of error, we can express the acceptable range of diameters for the cake as follows:

d - 24 ≤

This inequality states that the difference between the actual diameter "d" and the ideal diameter of 24 inches should be less than or equal to 3 inches, indicating that the actual diameter should be no more than 3 inches larger or smaller than 24 inches.

However, to represent this condition using an absolute value equation, we need to remove the inequality signs.

We can rewrite the inequality above using absolute value:

|d - 24| ≤ 3

This absolute value equation states that the absolute value of the difference between the actual diameter "d" and the ideal diameter of 24 inches should be less than or equal to 3 inches.

It encompasses both possibilities of the actual diameter being within 3 inches greater or smaller than 24 inches.

By using this absolute value equation, the chef can determine the range of cake diameters that meet the desired margin of error of 3 inches and make an informed decision when purchasing the cake.

Answer:

64π

Step-by-step explanation:

To calculate the surface area (S.A) of the circle with a radius (r) of 4 inches and a height (h) of 6 inches, we need to consider both the curved surface area (lateral surface area) and the area of the circular base.

The curved surface area, also known as the lateral surface area, is calculated using the formula:

L.A = 2πrh

Substituting the given values, we have:

L.A = 2π(4)(6)

L.A = 48π square inches

The area of the circular base is calculated using the formula:

A = πr^2

Substituting the given radius, we have:

A = π(4^2)

A = 16π square inches

To find the total surface area (S.A), we need to sum the lateral surface area (L.A) and the area of the circular base (A):

S.A = L.A + A

S.A = 48π + 16π

S.A = 64π square inches

Therefore, the surface area (S.A) of the given circle is 64π square inches.

To find the expression that is equivalent to 3(–2x – 1), we need to distribute the 3 to each term inside the parentheses.

When we distribute 3 to –2x, we get:

3 * –2x = –6x

When we distribute 3 to –1, we get:

3 * –1 = –3

Therefore, the expression equivalent to 3(–2x – 1) is:

–6x – 3.

While these examples demonstrate some practical applications, divisibility rules are primarily mathematical tools that assist in simplifying calculations, verifying results, and understanding number properties.

Divisibility rules can be applied in various real-life scenarios, particularly in mathematics, finance, and everyday calculations. Here are a few examples:

Checking for even or odd numbers: The divisibility rule for 2 states that a number is divisible by 2 if its last digit is even (0, 2, 4, 6, or 8). This rule can be helpful when determining if a given quantity or count is even or odd. For example, in inventory management, you can quickly estimate the number of items in a collection by checking the parity of the count.

Divisibility by 3: The divisibility rule for 3 states that a number is divisible by 3 if the sum of its digits is divisible by 3. This rule can be useful when dealing with numbers or quantities that need to be evenly distributed or divided.

Divisibility by 9: The divisibility rule for 9 states that a number is divisible by 9 if the sum of its digits is divisible by 9. This rule can be applied in various financial calculations, such as checking if a large number is divisible by 9 to verify the accuracy of calculations involving money, invoices, or balances.

Divisibility by 10: The divisibility rule for 10 states that a number is divisible by 10 if its last digit is 0. This rule is often used in practical situations like determining if a given quantity can be divided evenly into groups of 10 or used in financial transactions involving rounding to the nearest multiple of 10.

Checking prime numbers: Divisibility rules can also help in determining whether a number is prime. For example, the rule that states a number is not divisible by any number greater than its square root can be used to quickly eliminate potential factors when checking for primality.

The walkway is 12 feet 9 inches long.

To find the total length of the walkway, we need to add the lengths of the three boards together.

The first board is 3 feet 7 inches long, which can be written as 3'7".

The second board is 5 feet 4 inches long, which can be written as 5'4".

The third board is 3 feet 10 inches long, which can be written as 3'10".

Now, let's add the lengths together:

3'7" + 5'4" + 3'10"

When adding feet and inches, we need to carry over any extra inches beyond 12 to the feet.

Adding the inches first:

7" + 4" + 10" = 21"

Now, let's add the feet:

3' + 5' + 3' = 11'

So, the total length of the walkway is 11 feet 21 inches.

The value of y is 2 * √3.

In the second right triangle, we have a 60-degree angle and a leg opposite to that angle labeled y. The hypotenuse of the first right triangle is equal to the leg of the second right triangle.

Let's denote the hypotenuse of the first right triangle as h. From the first right triangle, we know that the vertical leg is equal to the square root of 2.

Using trigonometric ratios, we can relate the sides of a right triangle as follows:

sin(angle) = opposite/hypotenuse

In the first right triangle, the angle is 45 degrees, and the opposite side is the square root of 2. Therefore, we have:

sin(45 degrees) = √2 / h

By rearranging the equation, we can solve for h:

h = √2 / sin(45 degrees)

Using the value of sin(45 degrees) = 1/√2, we can simplify the equation:

h = √2 / (1/√2) = √2 * √2 = 2

Now, we can find the value of y in the second right triangle. Since the hypotenuse of the first right triangle is equal to the leg of the second right triangle, we have:

y = 2 * √3

Therefore, the value of y is 2 * √3.

Answer: rental is $415, and the standard deviation is $5.

Step-by-step explanation:

If about 99.7 percent of the monthly rentals fall between 400 and 430, it implies that this range encompasses three standard deviations from the mean.

To calculate the mean, we can find the midpoint of the given range:

Mean = (400 + 430) / 2 = 415

Since the range of three standard deviations covers about 99.7 percent of the data in a normal distribution, we can use this information to estimate the standard deviation (σ).

Standard deviation (σ) = (430 - 415) / 3 = 15 / 3 = 5

Therefore, based on the given information, the mean monthly rental is $415, and the standard deviation is $5.

Answer:

The distance from each chord to the center of the circle is approximately 12.09 inches.

Step-by-step explanation:

To find the distance from each chord to the center of the circle, we can use the following formula:

[tex]d = \sqrt{r^2-(l/2)^2}[/tex]

Where:

- "d" is the distance from the chord to the center of the circle,

- "r" is the radius of the circle, and

- "l" is the length of the chord.

Given that the diameter of the circle is 29 inches, we can find the radius by dividing the diameter by 2:

[tex]r = 29/2 = 14.5[/tex] Inches

Now, let's calculate the distance from each chord to the center of the circle:

For the first chord with a length of 16 inches:

[tex]d_{1} =\sqrt{14.5^2-(16/2)^2} = \sqrt{210.25-64} = \sqrt{146.25} = 12.09[/tex] Inches

For the second chord with a length of 16 inches:

[tex]d_{2} = \sqrt{14.5^2-(16/2)^2} = \sqrt{210.25-64} = \sqrt{146.25} = 12.09[/tex] Inches

Therefore, the distance from each chord to the center of the circle is approximately 12.09 inches.

Check the picture below.

[tex]\begin{array}{llll} \textit{using the pythagorean theorem} \\\\ a^2+o^2=c^2\implies o=\sqrt{c^2 - a^2} \end{array} \qquad \begin{cases} c=\stackrel{hypotenuse}{14.5}\\ a=\stackrel{adjacent}{8}\\ o=\stackrel{opposite}{x} \end{cases} \\\\\\ x=\sqrt{ 14.5^2 - 8^2}\implies x=\sqrt{ 210.25 - 64 } \implies x=\sqrt{ 146.25 }\implies x\approx 12.09[/tex]

The total number of data values (games played) represented in the table is 14.

To determine the total number of data values (games played) represented in the frequency table, we need to sum up the frequencies for each category (number of goals scored).

The frequency represents the number of games in which a particular number of goals was scored.

Let's calculate the total number of games played by summing up the frequencies:

Total number of games played =

Frequency of 0 goals + Frequency of 1 goal + Frequency of 2 goals + Frequency of 3 goals + Frequency of 4 goals + Frequency of 7 goals + Frequency of 9 goals

Total number of games played = 1 + 3 + 2 + 4 + 2 + 1 + 1

Total number of games played = 14

We must add the frequencies for each category (number of goals scored) to get the total number of data values (games played) reflected in the frequency table.

The number of games with a specific amount of goals scored is the frequency.

Let's add up the frequencies to determine the total number of games played:

Total games played = Frequency of 0 goals, Frequency of 1, Frequency of 2, Frequency of 3, Frequency of 4, Frequency of 7, and Frequency of 9 goals.

Step-by-step explanation:

Step 1:  Find total measure of ∠R:

Step 2:  Find total measure, m, of ∠Q:

m∠P + m∠Q + m∠R = 180

m∠Q = 180 - (m∠P + m∠R)

m∠Q = 180 - (60 + 76)

m∠Q = 180 - 136

m∠Q = 44°

Since QA bisects ∠Q into two congruent angles, we divide 44 by 2 to find the measures of each angle made by the bisector:  44/2 = 22.

Step 3:  Find x by setting the sum of the 38° angle, the 22° angle, and angle C equal to 180:

38 + (3x + 21) + 22 = 180

60 + 3x + 21 = 180

81 + 3x = 180

3x = 99

Then solve for y:

The inverse function is y= √x.

The elements in the range that correspond to the elements 0 and 3 are y = 2 and y = 4 and the equations are solved.

Given data ,

To find the elements in the range that correspond to the elements 0 and 3 of the domain, we need to solve the equation 3y - 2x = 6 for the corresponding values of y when x = 0 and x = 3.

When x = 0:

Substituting x = 0 into the equation 3y - 2x = 6, we get:

3y - 2(0) = 6

3y = 6

y = 2

So, when x = 0, the corresponding value of y is 2.

When x = 3:

Substituting x = 3 into the equation 3y - 2x = 6, we get:

3y - 2(3) = 6

3y - 6 = 6

3y = 12

y = 4

So, when x = 3, the corresponding value of y is 4.

Hence , the elements in the range that correspond to the elements 0 and 3 of the domain are y = 2 and y = 4, respectively.
