find the perimeter of a quadrilateral with vertices at C(2,4), D(1,1), E(5,0), and F(3,4). Round your answer to the nearest hundredth when necessary
Therefore, the perimeter of a quadrilateral at the given vertices is 12.76 units.
What is quadrilateral?A quadrilateral is a four-sided polygon with four edges and four corners that is used in geometry. The Latin words quadri, a variation of four, and latus, meaning "side," are the source of the name.
Define edges and corners.A face is a flat surface, an edge is a straight line connecting two faces, and a vertex is the corner of the form. Faces, edges, and vertices of three-dimensional forms are all unique. In the course of our daily activities, we come into contact with numerous things of all sizes and forms.
The length of each side:
CD: C(2,4) and D(1,1) = sqrt((1-2)^2 + (1-4)^2) = sqrt(1 + 9) = sqrt(10)
DE: D(1,1) and E(5,0) = sqrt((5-1)^2 + (0-1)^2) = sqrt(16+1) = sqrt(17)
EF: E(5,0) and F(3,4) = sqrt((3-5)^2 + (4-0)^2) = sqrt(4+16) = sqrt(20)
FC: F(3,4) and C(2,4) = sqrt((2-3)^2 + (4-4)^2) = sqrt(1) = 1
Perimeter of the quadrilateral = sum of the lengths of all four sides:
Perimeter = sqrt(10) + sqrt(17) + sqrt(20) + 1
Calculating, perimeter = 3.162+4.123+4.472+1 = 12.7557 and rounding to the nearest hundredth, it is 12.76

The product of a, b and c is equal to 18.
What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.
Given is are the expression as -

The given expression is -
[tex]$\frac{\sqrt[4]{81x^{4} y^{2} } }{x^{-1} 2y^{-1} }[/tex]
We can rewrite it as -
[tex]$\frac{(81x^{4} y^{2}) ^{\frac{1}{4} } }{x^{-1} (2y)^{-1} } = \frac{(3^{4} x^{4} y^{2})^{\frac{1}{4} } }{x^{-1} (2y)^{-1} } = 6xy^{\frac{1}{2} } xy[/tex]

For males in a certain town, the systolic blood pressure is normally distributed with a
mean of 105 and a standard deviation of 10. What is the probability that a randomly
selected male's systolic blood pressure will be less than 129, to the nearest
thousandth?
Therefore, the solution of given problem of probability is there is a 0.397 percent chance that a randomly chosen male will have a systolic blood pressure below 100.
How does probability work?A branch of mathematics called probability theory determines the likelihood that an event will occur or that a statement is true. A possibility is a number from 0 and 1, where 1 denotes certainty and about 0 denotes how probable an event is to occur. The possibility or chance that a specific event will occur is expressed numerically as a probability. Probabilities can also be expressed as percentages ranging from 0% to 100% and from 0 to 1.
Here,
Considering the query
In a particular municipality, men's systolic blood pressure has a median of 105 as well as a standard deviation = 9, which is considered to be regularly distributed.
Probability that the systolic blood pressure of a man chosen at random will be less than 100
P(x < 100)
Through the use of normalized normal distribution
=> N(100 -105)/9 \s=> N (-5/9)
We have a>0 and N(-a) = 1 - N(a).
=> 1 - N (-5/9)
=> 1 - N(0.556) (0.556)
=>1 - 0.6026
=> 0.3979
≈ 0.397 (nearest hundredths) (nearest thousandth)
Therefore, there is a 0.397 percent chance that a randomly chosen male will have a systolic blood pressure below 100.

What is a discrete variable?A discrete variable is one that can only have particular, unique values and cannot have any other values in between. The number of students who increase their score is a whole number that can only take on specific values (e.g., 0, 1, 2, etc.), indicating that it is a discrete variable.
A quantitative variable in mathematics and statistics can be continuous or discrete depending on whether it is normally obtained by measuring or counting. The variable is continuous in that interval if it can take on two specific real values while simultaneously taking on all real values between them.

Parallel lines are what?Geometry refers to parallel lines as beams, straight lines that never overlap. Parallel planes are those that never cross each other while occupying the same three-dimensional space. Curves which are equal with each other and keep a predetermined minimum separation from one another must not overlap or intersect. Parallel lines on a plane are those that always have the same distance between them. A parallel line cannot be crossed. Perpendicular lines are those that intersect directly at a 90 degree angle.
Here,
Given : PQ || MN
