Therefore, the probability that a randomly chosen product was prepared on preparation stations 6, 7, and 8 is 0.25, or 25%.
The probability that a randomly chosen product was prepared on preparation stations 6, 7, and 8 can be found using the formula:
P(event) = number of favorable outcomes / total number of possible outcomes
In this case, the number of favorable outcomes is 3, since there are 3 preparation stations that we are interested in (6, 7, and 8). The total number of possible outcomes is 12, since there are 12 preparation stations in total.
So, the probability that a randomly chosen product was prepared on preparation stations 6, 7, and 8 is:
P(event) = 3 / 12
P(event) = 0.25
Therefore, the probability that a randomly chosen product was prepared on preparation stations 6, 7, and 8 is 0.25, or 25%.

The area of the hexagon is 98 sq. m and option 3 is the correct answer.
What is a hexagon?The closed polygonal form of a regular hexagon has six equal sides and six equal angles. Any regular polygon has equal sides and angles on all sides. Regular pentagons, for instance, have 5 equal sides, while regular octagons have 8 equal sides. When these requirements are not satisfied, polygons might resemble many other asymmetrical forms. A regular hexagon is formed when six equilateral triangles are placed side by side. The regular hexagon's area then increases to six times that of the identical triangle.
Given that,
The scale factor of two similar hexagons is 3:7.
The ratio of the area will thus be,
(3/7)^2 = 9/49.
For the area of the smaller hexagon as 18 we have:
9/49 = 18/A
(9/49)A = 18
Multiplying both sides by 49/9, we get:
A = 98 sq. m
The volume of the hexagon cannot be determined by the given information.
Hence, the area of the hexagon is 98 sq. m and option 3 is the correct answer.

Subtract. (7)/(12vx^(2))-(3)/(8v^(2)x) Simplify your answer as much as possible.
Subtracting the expression (3)/(8v²x) from the expression (7)/(12vx²) will result to the expression (14v - 9x)/(24v²x²).
To subtract the two fractions, we need to find a common denominator. The least common denominator (LCD) is the least common multiple of the denominators of two or more fractions, and it is used to find a common denominator so that we can perform operations on them. The LCD of 12vx² and 8v²x is 24v²x². We can then multiply each fraction by the LCD to get the same denominator and subtract the numerators.
(7)/(12vx²) x (24v²x²)/(24v²x²) - (3)/(8v²x) x (24v²x²)/(24v²x²) = (14v)/(24v²x²) - (9x)/(24v²x²) = (14v - 9x)/(24v²x²)

Using the same function, when is fx=0
For function fx= -4x2+6x-1
f(-1) = -11 fx=0 when x = (3+√5)/4 and x = (3-√5)/4.To find f(-1), we need to plug in -1 for x in the function and simplify:
f(-1) = -4(-1)2+6(-1)-1
f(-1) = -4+(-6)-1
f(-1) = -11
To find when fx=0, we need to set the function equal to 0 and solve for x: -4x2+6x-1=0
We can use the quadratic formula to solve for x:
x = (-b ± √(b2-4ac))/(2a)
x = (-(6) ± √((6)2-4(-4)(-1)))/(2(-4))
x = (-6 ± √(36-16))/(-8)
x = (-6 ± √20)/(-8)

The solution of the inequality |x+3| < 2 is -5 < x < -1.
And the graph is given in the image below.
The correct option is C.
What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
To solve the inequality |x+3| < 2, we need to consider two cases:
Case 1: x+3 ≥ 0
In this case, the inequality simplifies to x+3 < 2, which gives us x < -1.
Case 2: x+3 < 0
In this case, the inequality simplifies to -(x+3) < 2, which gives us -x-3 < 2, or -x < 5, or x > -5.
Combining the results from both cases, we get the solution:
-5 < x < -1
To graph the solution, we draw an open circle at x=-3
(since the absolute value is less than 2, not less than or equal to), and shade the region between -5 and -1.
Therefore, the solution is -5 < x < -1.

If the constant of variation is 12 and y = 36 and they vary directly, what does x equal?
If the constant of variation is 12 and y = 36 and they vary directly, then x equals 3.
Direct variation is when two quantities, x and y, are related in such a way that the ratio of their values is always the same. This means that y = kx, where k is the constant of variation.
In this case, we are given that k = 12 and y = 36. We can plug these values into the equation to find x:
36 = 12x
To solve for x, we can divide both sides of the equation by 12:
36/12 = 12x/12
This simplifies to:
3 = x
Therefore, x equals 3.

What is an equation?An equation is an expression that shows the relationship between numbers and variables using mathematical operators such as addition, subtraction, exponent, multiplication and division.
The surface area of a cylinder is:
Surface area = 2πr(r + h)
where r is the radius and h is the height
1) r = 5 in., h = 11 in. and π = 3.14, hence:

Step-by-step explanation:
You want the area of triangle RST using the area formula A=1/2bh, given the points R(-2, 7), S(-5, 1), and T(7, -5).
Side lengthsA plot of the points is shown in the first attachment. By counting grid squares, you can see that segment RS has a "rise" of 2 grid squares for each 1 to the right. The total (run, rise) is ...
R -S = (-2, 7) -(-5, 1) = (-2 +5, 7 -1) = (3, 6)
The length of RS is found using the Pythagorean theorem (distance formula). It is ...
RS = √(3² +6²) = √45 = 3√5
Similarly the length of segment ST is ...
T -S = (7, -5) -(-5, 1) = (7 +5, -5 -1) = (12, -6)
ST = √(12² +(-6)²) = √180 = 6√5
SlopesWe note that the slopes of these segments are opposite inverses of each other:
slope RS = 6/3 = 2
slope ST = -6/12 = -1/2
This means the segments are at right angles. One of them can be considered to be the "base" and the other the "height" of the triangle.
AreaUsing the area formula, we find the area to be ...
A = 1/2bh
A = 1/2(6√5)(3√5) = (1/2·6·3)(√(5·5)) = 9·5 = 45
The area of ∆RST is 45 square units.
__
Alternate solution
When the coordinates of a polygon are given, there are several other ways to find its area. One of these is illustrated in the second attachment.
The method illustrated here computes successive "determinants", then finds the area as half the absolute value of their sum. (The sign of the sum will depend on the order in which the points are listed around the figure. Here, it is counterclockwise.) As you can see, we get the same result. You can also see that a spreadsheet is useful for doing the repetitive math.
Area ∆RST = 45 square units
__
Additional comment
The distance formula for the length of the segment between two points is ...
d = √((x2-x1)² +(y2-y1)²)
Above, we calculated the differences (x2-x1, y2-y1) separately, then used the "root sum squares" formula for the distance. This has the advantage that (y2-y1)/(x2-x1) is the slope of the segment, and we needed to make sure the segments were perpendicular.

Solve each system of equations by substitution. Clearly identify your solution.
y=3x+19
y=5x+33
Answer:
(x, y) = (-7, -2).
Step-by-step explanation:
To solve the system of equations:
y = 3x + 19
y = 5x + 33
We can use the substitution method, which involves solving one equation for one variable and substituting that expression into the other equation. Then we can solve for the remaining variable.
From the first equation, we can solve for y in terms of x:
y = 3x + 19
From the second equation, we can solve for y in terms of x:
y = 5x + 33
Now we can substitute the expression for y from the first equation into the second equation:
3x + 19 = 5x + 33
Simplifying this equation by subtracting 3x from both sides:
19 = 2x + 33
Subtracting 33 from both sides:
-14 = 2x
Dividing both sides by 2:
x = -7
Now that we have the value of x, we can substitute it back into either equation to find the value of y:
y = 3x + 19
y = 3(-7) + 19
y = -21 + 19
y = -2
The solution to the system of equations is (x, y) = (-7, -2).

Which graph shows the solution to the inequality? x + 2 < -3 A) A B) B C) C D) D
Therefore , the solution of the given problem of inequality comes out to be the inequality x -5 is option B.
What does inequality imply in reality?Regardless of the equal symbol, a connection or group of numbers variables can be an inequality in mathematics. Equilibrium is always followed by equity. Inequality happens when ideals are still incompatible. Differences exist between inequality expression and fairness. We chose to utilize the most prevalent symbol because elements aren't always similar or comparable (). No mater how few or many variations there are, they can all be used to evaluate values.
Here,
Option B) B is the proper response.
We must isolate x on one side of the inequality in order to answer the inequality x + 2 -3. By taking 2 away from both edges, we arrive at:
=> x < -5
According to this inequality, x is any integer that is less than -5. Since x cannot equal -5,
we must create an open circle at this point on the number line and shade to the left of it to represent all the different values of x that could be used.
Looking at the available choices, we can see that the only graph that accurately depicts the inequality x -5 is option B) B.

Caleb needs to place a ground cover
under a tent. The floor of the tent measures 82 feet by 92 feet.
He purchases a ground cover that states that it covers 90 square
feet. Will the ground cover be able to be used under the tent?
Explain your reasoning.
One cover is not enough to cover tent, Caleb will need at least 84 ground covers to cover the entire floor of the tent.
How to find the Cover area of the tent?To determine if the ground cover will be sufficient, we need to calculate the area of the tent floor and compare it with the area covered by the ground cover.
The area of the tent floor is:
82 feet x 92 feet = 7544 square feet
The area covered by one ground cover is:
90 square feet
To determine the number of ground covers needed to cover the tent floor, we can divide the area of the tent floor by the area covered by each ground cover:
7544 square feet ÷ 90 square feet ≈ 84
Therefore, Caleb will need at least 84 ground covers to cover the entire floor of the tent. As the number of ground covers required is greater than one, we can conclude that the ground cover will be able to be used under the tent.
