Answer:
Step-by-step explanation:
It means there is no solution and the lines are parallel. It is called an inconsistent system.
I hope this helps
The system has no solution. Thus, the lines are parallel to each other.
The system of the equation has no solution. The expression leads to the value that is 0=4, which means you concluded the final result as 0=4.
Do you think practically it is possible, never, it is not possible to equate zero with four, same in the solutions of the system in the lines, this kind of results will not be taken by the intersecting lines.
Hence, the above expression is the condition for "No Solution"
If we try to evaluate the solution of the system that has no solution or an infinite number of solutions, then the variables are canceled out and only the constant values are left that are not equal.
Therefore, The lines are parallel and the system of the equation has no solution.

To simplify the given expression, we can apply the rules of exponents.
First, we raise 3 to the power of 3 and 6 to the power of 6, individually:
3^3 = 27 and 6^6 = 46656.
Next, we multiply these two values together:
27 * 46656 = 1259712.
Now, we raise the result to the power of -3:
1259712^(-3).
To simplify this expression, we can rewrite it as the reciprocal of the base raised to the positive exponent:
(1 / 1259712^3).
This can be further simplified by raising the base to the power of 3:
(1 / (1259712 * 1259712 * 1259712)).
Finally, we can simplify the expression by multiplying the denominators:
1 / (1954890816015872).
Ina city school, 65% of students have green eyes. 25% have red hair, and 15% have green eyes and
red hair. What is the probability (rounded to the nearest whole percent) that a randomly selected
student will have red hair given that the student has green eyes?
Answer:
23% of student will have red hair given that the student has green eyes.
Step-by-step explanation:
We are given the following in the question:
Percentage of students that have green eyes = 65%
[tex]P(G) =0.65[/tex]
Percentage of students that have red hairs = 25%
[tex]P(R) =0.25[/tex]
Percentage of students that have green eyes and red hairs = 15%
[tex]P(G\cap R) =0.15[/tex]
We have to find the conditional probability of randomly selected student that will have red hair given that the student has green eyes.
[tex]P(R|G) = \dfrac{P(R\cap G)}{P(G)}[/tex]
Putting values, we get,
[tex]P(R|G)=\dfrac{0.15}{0.65} = 0.2307\approx 23\%[/tex]
Thus, 23% of student will have red hair given that the student has green eyes.

After opening day, theme park attendance has been tracked at a new park in Destin, FL..
Answer:
13.9% marginal
Step-by-step explanation:
The percentage of tickets sold to Seniors can be found as:
[tex]p(s)=\frac{S}{N}\cdot 100[/tex]
where
S is the number of all tickets sold to seniors
N is the total number of tickets sold
By looking at the table, we see that:
S = 32 + 14 + 54 = 100 is the number of tickets sold to seniors
N = 35 + 87 + 62 + 56 + 177 + 205 + 32 + 14 + 54 = 722 is the total number of tickets sold
Therefore, the percentage is:
[tex]p(s)=\frac{100}{722}\cdot 100 =13.9\%[/tex]
The three different types of frequencies are defined as:
- Joint: the frequency of a single category calculated with respect to the total number --> this is not the case
- Marginal: the frequency of an entire row/column over the total --> this is the case
- Conditional: the frequency of a single category over a subset of the total --> this is not the case
So, the correct answer is
13.9% marginal

Is the leading coefficient of the function positive or negative?
Answer:
Negative.
Step-by-step explanation:
To understand the question, you first must understand the slopes of different types of equations.
A linear equation: [tex]y = 2x[/tex] will travel from the third quadrant to the first.
If you plug in 2 for x, y will equal 4. Both values are positive, leading to a positive correlation.
A linear equation: [tex]y = -3x[/tex] will face the other direction, as shown in your attached image. When you plug in a positive number for x, like 5, y will equal -15, making the graph go up and left towards negative values.

On a coordinate plane, line A goes through points (negative 3, 0) and (0, 4), and line B goes through points (0, negative 4) and (2, 0). Which line has the steeper slope? Line has a steeper slope
Answer:
Line B
Step-by-step explanation:
I got it right
Line B has a steeper slope than line A because its slope is greater than the slope of line A.
What is the slope of the line?The slope of a line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
For line A, the two points are (-3, 0) and (0, 4).
Plugging these values into the formula, we get:
slope = (4 - 0) / (0 - (-3)) = 4 / 3
For line B, the two points are (0, -4) and (2, 0).
Plugging these values into the formula, we get:
slope = (0 - (-4)) / (2 - 0) = 4 / 2 = 2
Therefore, line B has a steeper slope than line A, because its slope is greater than the slope of line A. Line A has a slope of 4/3, while line B has a slope of 2.
We can also visualize this by drawing the lines on a coordinate plane. Line B will have a more steeply inclined slope than line A, as it will rise more quickly as it moves from left to right.

The parks department is installing a new picnic area that measures 20 yards by 48 feet.
They are going to cover the new picnic area with square pieces of sod.
If the sod costs $11 per square yard, how much will the parks department pay to completely cover the picnic area with sod?
Answer:
$3520
Step-by-step explanation:
Conversion
To convert feet to yards, we divide the measurement of feet by 3 hence for dimenaion given as 48 ft, it will be 48÷3=16 yards
The area will be given by the product of length and width and since both measurements are given
A=lw
A=16*20=320 yd²
Cost will be 320*11=$3520
Therefore, the department will have to pay $3520 for the work to be completed
A cylindrical block of cheese has a 6-inch diameter and is 2 inches thick. After a party, only a sector remains that has a central angle of 45 degrees. Find the volume of the cheese that remains. Show all work
Answer: The volume of cheese remaining is 7 cubic inches (7 in³)
Step-by-step explanation: The cheese is in the shape of a cylinder. The volume of a cylinder is given as follows;
Volume = πr²h
Where r = radius of the top of the cylinder and h = the height of the cylinder.
In this case, the cheese has its radius as 3 inches (that is diameter divided by 2). Also the height is given as the thickness of the cheese which is 2 inches. Note also that part of the cylindrical cheese has been eaten leaving only a potion which has an angle of 45 degrees.
The volume of the left over portion therefore can be calculated as follows;
Volume = (∅/360) x πr²h
Volume = (45/360) x 3.14 x 3² x 2
Volume = (1/8) x 3.14 x 9 x 2
Volume = (1/8) x 56.52
Volume = 7.065
Volume ≈ 7
Therefore the volume of cheese that remains is 7 cubic inches (7 inches³) approximately.

x=6
Answer:
x=6
Step-by-step explanation:
x=6 because if you simplify this equation you get 3 + 2x = 15. The first step to solving a equation is having the x value on one side of the equation and the number value on one side. to do this we can subtract 3 from both sides of the equation and get the equation 2x=12. which would mean x=6.

What is the length of side s of the square shown below?
The length of side "s" of the square is 3 units, as it is equal to one of the legs of the 45-45-90 right triangle formed by the diagonal of the square.
To find the length of side "s" of the square shown below, we can use trigonometry, specifically the properties of right triangles and the fact that the diagonal divides the square into two congruent 45-45-90 right triangles.
Given information:
The diagonal of the square measures 6 units.
One of the angles at the top of the square is 45 degrees.
Step 1: Recognize the properties of the 45-45-90 triangle:
Since the diagonal divides the square into two congruent right triangles, and one angle is 45 degrees, we have a 45-45-90 triangle. In such a triangle, the two legs (the sides opposite the 45-degree angles) are congruent, and the hypotenuse (the side opposite the 90-degree angle) is √2 times the length of a leg.
Step 2: Use trigonometric ratios:
Let "x" be the length of one leg of the 45-45-90 triangle, which is also equal to side "s" of the square.
From the properties of the 45-45-90 triangle:
x (leg) = s (side of the square)
Hypotenuse = √2 * leg
Given that the diagonal of the square is 6 units, we can relate the diagonal to the legs:
Diagonal = 2 * leg
6 = 2 * x
Now, solve for x (the length of one leg of the triangle and side "s" of the square):
x = 6 / 2 = 3 units
So, the length of side "s" of the square is 3 units.
Therefore, from the given options the correct one is B.

19. Find the area of a circle with a
circumference of 18.84 yards.
Answer:
28.25
Step-by-step explanation:
Final answer:
The area of a circle with a circumference of 18.84 yards is approximately 28.274 square yards, found by first calculating the radius from the circumference and then using the area formula πr².
Explanation:
To find the area of a circle with a given circumference, we first need to determine the radius of the circle using the circumference. The formula to find the circumference C is C = 2πr, where r is the radius of the circle and π (pi) is approximately 3.14159. Since we are given that the circumference C is 18.84 yards, we solve for the radius r as follows:
r = C / (2π)
r = 18.84 yd / (2 × 3.14159)
r = 3 yards (approximately)
Once we have the radius, we can calculate the area of the circle using the formula:
A = πr²
A = π × (3 yd)²
A = 3.14159 × 9 yd²
A = 28.274 yards² (approximately)
Therefore, the area of the circle with a circumference of 18.84 yards is roughly 28.274 square yards.
