The statement is not true, since 13 is not less than 6. Therefore, the point (3, 2) is not a solution of the linear inequality 3x + 2y < 6.
To determine if the point (3, 2) is a solution of the linear inequality 3x + 2y < 6, we substitute the values of x and y in the inequality and check if it is a true statement or not.
A linear inequality is an inequality in which the variables have a degree of one, and the inequality can be expressed as a linear equation with an inequality symbol. A linear inequality can be represented graphically as a line with a shaded region that either includes or excludes certain points in the coordinate plane.
For example, the inequality 2x + 3y > 6 is a linear inequality. To graph this inequality, we can first plot the line 2x + 3y = 6 by finding its x and y intercepts, which are (3, 0) and (0, 2), respectively. Then, we can choose a test point not on the line, such as (0, 0), and substitute its coordinates into the inequality to see if it is a solution.
3(3) + 2(2) < 6
9 + 4 < 6
13 < 6
The statement is not true, since 13 is not less than 6. Therefore, the point (3, 2) is not a solution of the linear inequality 3x + 2y < 6.

A circle is inscribed in a regular hexagon with side length 2 units.
What is the exact area of the circle?
The exact area of the inscribed circle is 12π square units.
What is circle?A circle is a geometric shape consisting of all the points in a plane that are equidistant from a given point called the center of the circle. The distance between the center and any point on the circle is called the radius of the circle.
According to question:The radius of the inscribed circle is also the distance from the center of the hexagon to each of its sides. To find this distance, we can divide the hexagon into six equilateral triangles, each with side length 2 units. The height of each triangle is √3 times the side length, or 2√3 units. The distance from the center of the hexagon to each side is equal to this height, or 2√3 units.
Therefore, the radius of the inscribed circle is 2√3 units. The area of the circle is given by the formula A = πr², where r is the radius. Substituting in the value of the radius, we get:
A = π(2√3)² = 12π
So the exact area of the inscribed circle is 12π square units.

An element with a mass of 540 grams decays by 12.8% per minute. To the nearest tenth of a minute, how long will it be until there are 110 grams of the element remaining?
Therefore, to the nearest tenth of a minute, it will be about 9.4 minutes until there are 110 grams of the element remaining.
What is initial amount?"Initial amount" usually refers to the starting quantity or value of something, such as money, an investment, or a substance. It is the amount or quantity that exists at the beginning of a particular time period or situation. For example, if you invest $1,000 in a savings account, the initial amount is $1,000. Similarly, if you are given 10 liters of water, the initial amount of water is 10 liters.
We can use the exponential decay formula to solve this problem:
[tex]N(t) = N₀ * e^{(-kt)}[/tex]
where N(t) is the amount of the element remaining at time t, N₀ is the initial amount of the element, k is the decay constant (which is equal to ln (1 - 0.128) = -0.142), and e is the base of the natural logarithm.
We can plug in the given values and solve for the time t when the remaining amount N(t) is equal to 110 grams:
[tex]110 = 540 * e^{(-0.142t)}[/tex]
Dividing both sides by 540, we get:
[tex]0.2037 = e^{(-0.142t)}[/tex]
Taking the natural logarithm of both sides, we get:
[tex]ln(0.2037) = -0.142t[/tex]
Solving for t, we get:
t = ln (0.2037) / (-0.142) ≈ 9.4 minutes
Therefore, to the nearest tenth of a minute, it will be about 9.4 minutes until there are 110 grams of the element remaining.

A farmer finds there is a linear relationship between the number of bean stalks, n , she plants and the yield, y, each plant produces. When she plants 30 stalks, each plant yields 25 oz of beans. When she plants 32 stalks, each plant produces 24 oz of beans. Find a linear relationship in the form y=mn+b that gives the yield when n stalks are planted.
The linear relationship between the number of bean stalks, n, and the yield, y, is y = -0.5n + 40. This equation can be used to predict the yield of beans for any number of bean stalks planted by the farmer.
To find the linear relationship between the number of bean stalks, n, and the yield, y, we can use the two data points provided by the farmer. We know that when 30 stalks are planted, each plant yields 25 oz of beans, and when 32 stalks are planted, each plant yields 24 oz of beans.
First, we need to find the slope, m, of the line. We can use the formula:
m = (y2 - y1) / (x2 - x1)
where x1 = 30, y1 = 25, x2 = 32, and y2 = 24.
m = (24 - 25) / (32 - 30) = -0.5
Next, we need to find the y-intercept, b, of the line. We can use the point-slope form of the equation:
y - y1 = m(x - x1)
where x1 = 30 and y1 = 25.
y - 25 = -0.5(x - 30)
y - 25 = -0.5x + 15

What percentage of the sample means will be greater than 144 but less than 152 seconds? (Round the z values to 2 decimal places and the final answers to 2 decimal places.) Percentage %
a. The shape of the distribution of the sample mean will be approximately normal, according to the Central Limit Theorem.
b. The standard error of the mean is given by:
SE = σ / sqrt(n)
where σ is the population standard deviation (8 seconds), and n is the sample size (26). Substituting the given values, we get:
SE = 8 / sqrt(26) ≈ 1.57 seconds
Rounded to 2 decimal places, the standard error of the mean is 1.57 seconds.
c. To find the percentage of sample means that will be greater than 152 seconds, we need to calculate the z-score corresponding to a sample mean of 152 seconds:
z = (x - μ) / (σ / sqrt(n))
where x is the sample mean (152 seconds), μ is the population mean (148 seconds), σ is the population standard deviation (8 seconds), and n is the sample size (26).
Substituting the given values, we get:
z = (152 - 148) / (8 / sqrt(26)) ≈ 1.98
Using Appendix B.1, we find that the area to the right of a z-score of 1.98 is 0.0242, or 2.42%. Therefore, approximately 2.42% of the sample means will be greater than 152 seconds.
d. To find the percentage of sample means that will be greater than 144 seconds, we need to calculate the z-score corresponding to a sample mean of 144 seconds:
z = (x - μ) / (σ / sqrt(n))
where x is the sample mean (144 seconds), μ is the population mean (148 seconds), σ is the population standard deviation (8 seconds), and n is the sample size (26).
Substituting the given values, we get:
z = (144 - 148) / (8 / sqrt(26)) ≈ -1.98
Using Appendix B.1, we find that the area to the right of a z-score of -1.98 is also 0.0242, or 2.42%. Therefore, approximately 2.42% of the sample means will be less than 144 seconds.
e. To find the percentage of sample means that will be greater than 144 but less than 152 seconds, we need to find the area between the z-scores corresponding to sample means of 144 and 152 seconds.
The z-score corresponding to a sample mean of 144 seconds is:
z1 = (144 - 148) / (8 / sqrt(26)) ≈ -1.98
The z-score corresponding to a sample mean of 152 seconds is:
z2 = (152 - 148) / (8 / sqrt(26)) ≈ 1.98
Using Appendix B.1, we find that the area to the right of a z-score of -1.98 is 0.0242, and the area to the right of a z-score of 1.98 is 0.0242. Therefore, the area between these two z-scores is:
0.5 - 0.0242 - 0.0242 = 0.4516
Multiplying by 100, we get that approximately 45.16% of the sample means will be greater than 144 but less than 152 seconds.

Step-by-step explanation:
You want to take out a $210,000 mortgage (home loan).The yearly interest rate on the loan is 6%, and the loan is for 30 years. How much will your monthly payment be?
Using the formula for calculating monthly mortgage payments, with a loan amount of $210,000, yearly rate of 6% and time period of 30 years, the monthly mortgage payment comes out to be approximately $1,259.81.
Explanation:The calculation that needs to be done here involves a formula related to annuities, which is what monthly mortgage payments are classified as. The formula used to calculate a monthly mortgage payment is:
[tex]M = P [r(1 + r)^n]/[(1 + r)^n - 1][/tex]
Where:
M = monthly mortgage payment
P = loan amount (present value)
r = monthly interest rate
n = total number of payments (or total number of periods)
Plugging our given values into the equation:
P = $210,000 (this is the loan amount)
r = 6/100/12 = 0.005 (this is the monthly interest rate)
n = 30 x 12 = 360 (this is the number of periods, ie the total number of monthly payments over 30 years)
By substituting these values, one can calculate that:
M = [tex]210,000[0.005(1 + 0.005)^3^6^0] / [(1 + 0.005)^3^6^0 - 1][/tex]
Calculating this, we get M ≈ $1,259.81

Find the value of � x, � y, and � z, in the rhombus below. 71 -8x+7 y+7 2z+5
I believe you meant to write the expression as follows: 71 = -8x + 7y + 7z + 5. This equation represents a relation between the values of x, y, and z in a rhombus where 71 is the sum of the diagonals of the rhombus.
How to calculate value of x,y and z for the given rhombus?
To solve for x, y, and z, we need to use additional information about the rhombus. Without any further information, we cannot determine unique values for x, y, and z.
However, we can make some observations based on the given equation:
The coefficient of x is negative (-8), which means that increasing x would decrease the value of the left-hand side of the equation. Therefore, we can conclude that x must be positive to satisfy the equation.
The coefficients of y and z are positive (7 and 7, respectively), which means that increasing y and/or z would increase the value of the left-hand side of the equation. Therefore, we can conclude that y and z must be non-negative to satisfy the equation.
With these observations in mind, we can come up with multiple solutions for x, y, and z that satisfy the given equation. Here are a few examples:
If we let x = 0, y = 11, and z = 9, then the equation is satisfied:
71 = -8(0) + 7(11) + 7(9) + 5
71 = 77
If we let x = 2, y = 10, and z = 8, then the equation is also satisfied:
71 = -8(2) + 7(10) + 7(8) + 5
71 = 71
Therefore, we cannot determine a unique solution for x, y, and z based on the given equation alone.

ƒ'(3) = 2(3) = 6
Therefore, the slope of the curve ƒ(x) = x^2 + 2 at x = 3 is 6.

32 +×= 108 ×= 76°
It seems that the problem solved incorrectly is the one represented by letter A, which is trying to find the missing angle in a triangle. The correct answer is 74.1°, which can be obtained by subtracting the sum of the other two given angles (83.2° and 22.7°) from 180°.
The problem that Anna solved incorrectly is the last one: 32 + x = 108. The correct answer should be x = 76, not x = 108.
Explanation:In this math problem, Anna seems to be solving for unknown angles in several triangle problems. An important principle here is that the sum of the angles in a triangle always adds up to 180 degrees. Looking at the problems she solved:
83.2 + 74.1 + x = 180: The correct answer for x here is 22.7 degrees, and Anna solved it correctly.42 + 36.08 + x = 180: The correct answer for x here is 101.92 degrees, and Anna also solved this correctly.32 + x = 108: Misstep appears here. If we subtract 32 from both sides of the equation, the correct answer for x should be 76 degrees. However, Anna seems to have calculated x = 108, which is incorrect.So, the problem that was solved incorrectly is the last one: 32 + x = 108.

The probability of Z being greater than 1.2 is 0.11507, or approximately 11.51% (rounded to two decimal places).
What do you mean by probability?Probability is a mathematical concept that expresses the possibility or chance of an event happening.
A number between 0 and 1, with 0 signifying impossibility and 1 signifying certainty, is used to symbolize it.
The likelihood of an event occurring increases as the probability approaches 1.
To find the probability P(Z > 1.2) where Z follows a standard normal distribution, we need to use the standard normal distribution table or a calculator with a normal distribution function.
Using a standard normal distribution table, we look for the probability value that corresponds to a standard normal deviate of 1.2.
The table gives us the area under the standard normal curve to the left of 1.2, which is 0.88493. Therefore, the probability of Z being greater than 1.2 is:
P(Z > 1.2) = 1 - P(Z ≤ 1.2)
= 1 - 0.88493
= 0.11507

Amplitude of attached graph is 800 and here amplitude explains the maximum change in volume as compare to average volume.
Let us consider two point on the attached graph.
Lowest point as ( 0.5, 1000 )
Highest point as ( 2.5 , 2600 )
In a periodic function the volume of air in a person's lungs over time,
The amplitude is the distance between the maximum value of the function and its average value.
It is represented by y-coordinate.
Amplitude = ( 2600 - 1000 ) / 2
= 1600 / 2
= 800
In the context of the volume of air in a person's lungs,
The amplitude represents the maximum change in the volume of air from the average volume.
This is an important measure of lung function.
As it indicates how much air a person can take in and expel from their lungs with each breath.

Can someone please help me with this problem involving Proofs of proportions or angle congruences using similarity.
By SAS congruence, triangles ΔVTW and ΔUTX are congruent.
Define SAS congruenceSAS congruence (Side-Angle-Side) is a criterion for the congruence of two triangles in Euclidean geometry. Two triangles are said to be congruent by SAS if they have two pairs of corresponding sides that are congruent, and the included angle between those sides is also congruent.
Formally, the SAS congruence theorem states that if two sides and the included angle of one triangle are congruent to the corresponding two sides and included angle of another triangle, then the triangles are congruent. In symbols, if triangle ABC is congruent to triangle DEF by SAS, we write:
AB = DE
AC = DF
∠A = ∠D
In the triangle ΔVTW and ΔUTX
TX/TW=TU/TV (given)
∠VTW=∠UTX(Vertically opposite angle)

y varies directly as the square root of z. If y = 36, then z = 36.
Equation: [tex]y=k\sqrt{z}[/tex].
Value of the constant of proportionality (k): 6.
Step-by-step explanation:1. Write the equation using variables.So if y varies directly as the square root of z, there's a constant coefficient (k) multiplying the square root of z. Why? Because taking the square root of z will reduce it's value, then a number (k) must be multiplying it to make it match the value of y.
So:
[tex]y=k\sqrt{z}[/tex]
2. Substitute the equation with the given values.[tex]y = 36;\\ \\z = 36;\\ \\(36)=k\sqrt{(36)}\\ \\[/tex]
3. Divide both sides of the equation by [tex]\sqrt{36}[/tex] to calculate the value of k.[tex]\frac{36}{\sqrt{(36)}} =\frac{k\sqrt{(36)}\\ \\}{\sqrt{(36)}} \\ \\\frac{36}{6} =k\\ \\k=6[/tex]

Bear in Mind!Equations are mathematical statements that show that two quantities are equal. They typically contain an equal sign (=) and one or more variables. Equations are used to express relationships between quantities and to solve problems in various fields of science, engineering, and mathematics.
Example equations include:
[tex]\sf -4t^2 - 16t = -8[/tex][tex]\sf -2x + 5 = 13[/tex][tex]\sf -\dfrac{y}{7} = 3[/tex]To solve an equation, we want to determine the value of the variable(s) that make the equation true.
There are different techniques to solve equations, but some common steps include:
1. Simplify both sides of the equation by combining like terms and using the order of operations if necessary.
2. Isolate the variable on one side of the equation by undoing any operations that were performed on it.
For example, if the variable is multiplied by a number, divide both sides of the equation by that number. If the variable is added to a number, subtract that number from both sides of the equation.3. Check the solution by plugging it back into the original equation to see if it makes the equation true.
