Is equidistant the same as parallel?
In Euclidean geometry, parallel lines (lines that never intersect) are equidistant in the sense that the distance of any point on one line from the nearest point on the other line is the same for all points.
A point is said to be equally far from a group of objects if there is an equal distance between it and each member of the group.
The perpendicular bisector of two specified (different) points is their location in two-dimensional Euclidean geometry. The locus of points equidistant from two provided points in three dimensions is a plane, and generalizing further, the locus of points equidistant from two given locations in n-dimensional space is a (n1)-space.
The circumcenter of a triangle is a location that is equally spaced from each of the three vertices.

What stays the same when you perform a rigid motion transformation?
When a point or object is moved but its size and shape don't change, it is said to have undergone rigid motion, sometimes referred to as a rigid transformation.
What is rigid motion transformations?The separation between each pair of the geometric object's points is preserved during a rigorous change of the object. In other words, a rigid transformation maintains the object's size and shape. For instance, the rigid transformation of a triangle retains the angles and lengths of the triangle. Imagine a stiff shape distortion, similar to a cardboard shape. The form remains the same after being pushed left and right, rotated, and flipped.
When the mold was created using putty, the opposite was true. The thing can then be twisted and stretched. These conversions, nevertheless, are not exact. Stretching a form alters the distances between each pair of its points.

find the probability with which bob plays l in the mixed strategy equilibrium (round your answer to the 4th decimal).
The probability with which bob plays l in the mixed strategy equilibrium = 0.9090
What is Probability?
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Here suppose Alice plays U with probability P and D * with probability ( 2 - P)
Therefore, when Bob plays L, Bob gets payoff 8 with probability P and (2) with probability ( 2 - P). Hence
= 8 * P + 2 * ( 2 - P)
= 8P +4 - 4P
= 4 + 8P
Also, when Bob plays R, Bob gets pay off 4 with probability P and 7 probability (2-P). Hence expected payoff is
= 4*P+7(2-P)
= 4P+14-7P
=14-3P
At mixed strategy nash equilibrium the expected payoffs are equal. hence,
4 +8P = 14-3P
3P+8P = 14-4
11P = 10
P = 10/11
P = 0.9090
In the mixed strategy equilibrium, Bob's chances of playing l are equal to 0.9090.

The vertical asymptotes of a function can be found by setting the denominator equal to zero and solving for x. This will give the x-values that the function cannot approach as it approaches infinity.In other words, a vertical asymptote is a line that the graph of a function approaches but never touches. This line is the result of the denominator of a rational function becoming equal to zero. When this happens, the function is undefined at that value of x. To find the vertical asymptotes of a function, one must first factor the denominator and set each factor equal to zero. Then, solve each factor for x to get the x-values of the vertical asymptotes. It is important to note that a vertical asymptote can also appear if the numerator of a rational function is equal to zero. In this case, the vertical asymptote is the x-value at which the numerator is equal to zero.

Aume thathe ink in the printer wa already changed before beginning and that you have to complete each packet before completing any tep for the next one. How many welcome packet will you be able to fully complete in the time allotted?
Answer:
To complete each welcome packet, it will take a total of 5 minutes to print + 2 minutes to organize + 5 minutes to proofread = 12 minutes.
If it takes 3 minutes to change the ink in the printer every 5 packets, you will need to change the ink in the printer every 5 packets * 12 minutes per packet = 60 minutes.
In total, it will take you 60 minutes to change the ink in the printer + 12 minutes per packet to complete each packet, for a total of 60 minutes + (12 minutes/packet * number of packets) = 72 minutes per packet.
In the time allotted, you have 3 hours * 60 minutes/hour = 180 minutes.
Therefore, you will be able to fully complete 180 minutes / 72 minutes per packet = 2.5 packets.

A construction worker is pouring concrete stairs. The first step requires 1. 8 cubic feet of concrete, and the first 5 steps require a total of 27 cubic feet. If the steps follow an arithmetic series, how much concrete is required for the first 12 steps? 259. 2 cubic feet 43. 2 cubic feet 156 cubic feet 140. 4 cubic feet.
We can follow Arithmetic series, then the number of cubic feet concrete is required for the first 12 steps = 140.4 cubic feet.
Given that,
The first step requires 1. 8 cubic feet of concrete,
The first 5 steps require a total of 27 cubic feet.
An arithmetic series is the sum of the terms in an arithmetic sequence with a definite number of terms. Following is a simple formula for finding the sum: Formula 1: If [tex]S_{n}[/tex] represents the sum of an arithmetic sequence with terms , then. This formula requires the values of the first and last terms and the number of terms.
For an arithmetic series
[tex]a , a+d , a+2d , a+3d , .......[/tex]
where a is the first term and d is the common difference, the sum of n terms equals,
[tex]S_{n}[/tex] = [tex]a_{n} +(\frac{n(n-1)}{2} ) d[/tex] (Equation-1)
Since the first step requires 1.8 cubic feet of concrete, a = 1.8.
Now, the first 5 steps require 27 cubic feet of concrete, that is,
[tex]S_{5}[/tex] = 27
a = 1.8
n = 5
We can substitute values in equation-1,
[tex]S_{n}[/tex] = [tex]a_{n} +(\frac{n(n-1)}{2} ) d[/tex]
[tex]S_{5}[/tex] = (5) (1.8) + [tex](\frac{5(5-1)}{2} )d[/tex]
[tex]S_{5}[/tex] = (5) (1.8) + [tex](\frac{5*4}{2} )d[/tex]
[tex]S_{5}[/tex] = (5) (1.8) + [tex]\frac{20}{2} d[/tex]
[tex]S_{5}[/tex] = (5) (1.8) + 10 d
[tex]S_{5}[/tex] = 9 + 10 d
Then, [tex]S_{5}[/tex] = 27
27 = 9 + 10d
27 - 9 = 10d
18 = 10d
d = [tex]\frac{18}{10}[/tex]
d = 1.8
Find the concrete required for 12 steps.
Then, we can substitute n = 12
So,
We can write,
[tex]S_{n}[/tex] = [tex]a_{n} +(\frac{n(n-1)}{2} ) d[/tex]
[tex]S_{12}[/tex] = (12) (1.8) + [tex](\frac{12(12-1)}{2} )d[/tex]
[tex]S_{12}[/tex] = (12) (1.8) + [tex]\frac{12*11}{2} d[/tex]
[tex]S_{12}[/tex] = (12) (1.8) + [tex]\frac{132}{2} d[/tex]
[tex]S_{12}[/tex] = (12) (1.8) + 66 d
[tex]S_{12}[/tex] = 21.6 + 66 d
We can substitute d = 1.8
[tex]S_{12}[/tex] = 21.6 + 66 (1.8)
[tex]S_{12}[/tex] = 21.6 + 118.8
[tex]S_{12}[/tex] = 140.4
Therefore,
We can follow Arithmetic series, then the number of cubic feet concrete is required for the first 12 steps = 140.4 cubic feet.

What is the mean deviation of first 10 even natural numbers A 5 B 5.5 C 10 D 10 5?
To find the mean deviation of a set of numbers, you need to first find the average (mean) of the set, and then for each number in the set, subtract the mean and take the absolute value of the result. The mean deviation is then the average of these absolute values.
For the first 10 even natural numbers (2, 4, 6, 8, 10, 12, 14, 16, 18, 20), the mean is (2 + 4 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20) / 10 = 60/10 = 6.
To find the mean deviation, you would subtract the mean from each number, take the absolute value of the result, and then average those values. The mean deviation of the first 10 even natural numbers is therefore (|6 - 2| + |6 - 4| + |6 - 6| + |6 - 8| + |6 - 10| + |6 - 12| + |6 - 14| + |6 - 16| + |6 - 18| + |6 - 20|) / 10 = (4 + 2 + 0 + 2 + 4 + 6 + 8 + 10 + 12 + 14) / 10 = 5.5.
So the answer is B: 5.5.

If a and b are real numbers then a+b is a real number.This law is called ?
Step-by-step explanation:
This law is called the closure property of real numbers. It states that if a and b are real numbers, then their sum, a + b, is also a real number. This is because the set of real numbers is closed under addition, which means that any operation performed on real numbers will result in another real number.
For example, if a = 3 and b = 4, then a + b = 7, which is a real number. Similarly, if a = -2 and b = 3, then a + b = 1, which is also a real number.
The closure property of real numbers holds for many other mathematical operations as well. For example, the product of two real numbers is also a real number, as is the quotient of two real numbers (assuming that the divisor is not zero). The set of real numbers is also closed under subtraction and negation.
The population of a city has increased by 27% since it was last measured. If the current population is 63,500 , what was the previous population?
Answer:
50000
Step-by-step explanation:
We know it increase 27% since it was last measured
100% + 27% = 127%
We have to find 1%
We take 63500 divided by 127 = 500
500 times 27 = 13500
Now we have to take 63500 and subtract by 13500 to find the previous population.
63500 - 13500 = 50000
So, the previous population is 50000
The coordinate 2 has a weight of 2,

Find the weighted average.
The coordinates' weighted average is 4
How is the weight average calculated?The "weighted average" is the average of a group of numbers, each of which has a unique "weight" or value. Add the results after dividing each number by its weight to obtain the weighted average. A weighted average or mean is one in which, as opposed to considering each item equally, each item being averaged is multiplied by a number (weight) based on the item's relative importance.The given parameters are:
Coordinate 2 has a weight of 2
Coordinate 3 has a weight of 2
Coordinate 10 has a weight of 1
The weight average is then calculated as:
Weight average = Sum of (Weight * Coordinate)/Sum of Weights
So, we have:
Weight average = (2 × 2 + 3 ×2 + 10 × 1)/(2 + 2 + 1)
Evaluate the quotient
Weight average = 4

Solve this system of equations by graphing. First graph the equations, and then type the solution.
The graph of the equation given is mentioned below.
What is plot point in graph ?
Whenever we draw a point on our grid, we'll call it "plotting a point." The grid is really called a "graph" and the points we plot are called "coordinates." These are really locations on a plane -- we're just finding and labeling them.
Equation given,
y = 3/5x - 1 ----eq(i)
y = 2/5x -----eq(ii)
Now, for this two equation we infinite points for real numbers.
Now, take some points to plot the graph.
First for the eq(i)
Put x = 0, so y = -1
Put x = 5, so y = 2
Points for eq(i) is (0, -1) and (5, 2)
Now, for eq(ii)
Put x = 0, so y = 0
Put x = 5, so y = 2
Points for eq(ii) is (0, 0) and (5, 2)
Common point is (5, 2)
Now, plot this point on graph.
Hence, for more clarity graph of the equation given is mentioned below.

Is the system of linear equations 2x 3y 9 0 and 4x 6y 18 consistent justify your answer?
Consistency exists inside the linear equation system.
To determine whether a system of linear equations is consistent, you can try to solve the system to find the values of the variables that satisfy all of the equations. The system is consistent if it has at least one solution. If the system has no solutions, then it is inconsistent.
In this case, the system of linear equations is 2x + 3y - 9 = 0 and 4x + 6y - 18 = 0.
To solve this system, you can use algebraic methods such as substitution or elimination. Using substitution, you can solve one of the equations for one of the variables in terms of the other, and then substitute this expression into the other equation to solve for the other variable. For example, you could solve the first equation for y:
2x + 3y - 9 = 0
3y = 9 - 2x
y = (9 - 2x)/3
Then, you could substitute this expression for y into the second equation to solve for x:
4x + 6((9 - 2x)/3) - 18 = 0
4x + (54 - 12x)/3 - 18 = 0
(12x - 54)/3 + 4x - 18 = 0
(12x - 72)/3 = 0
12x - 72 = 0
12x = 72
x = 6
Substituting this value for x back into the first equation, you can solve for y:
2(6) + 3y - 9 = 0
12 + 3y - 9 = 0
3y = -3
y = -1
Therefore, the solution to this system of equations is x = 6 and y = -1. Since there is at least one solution, this system is consistent.
The complete question is:-
