Let A be the set of all lines in the plane. Define a relation R on A as follows. For every l1 and l2 in A, l1 R l2 ⇔ l1 is parallel to l2. (Assume that a line is parallel to itself). Which of the following is true for R?
A. R is reflexive.
B. R is symmetric.
C. R is transitive.
D. R is neither reflexive, symmetric, nor transitive.
Answer:
Hence, the relation R is a reflexive, symmetric and transitive relation.
Given :
A be the set of all lines in the plane and R is a relation on set A.
[tex]R=\{l_1,l_2\in A|l_1 \;\text{is parallel to}\; l_2\}[/tex]
To find :
Which type of relation R on set A.
Explanation :
A relation R on a set A is called reflexive relation if every [tex]a\in A[/tex] then [tex](a,a)\in R[/tex].
So, the relation R is a reflexive relation because a line always parallels to itself.
A relation R on a set A is called Symmetric relation if [tex](a,b)\in R[/tex] then [tex](b,a)\in R[/tex] for all [tex]a,b\in A[/tex].
So, the relation R is a symmetric relation because if a line [tex]l_1[/tex] is parallel to the line [tex]l_2[/tex] the always the line [tex]l_2[/tex] is parallel to the line [tex]l_1[/tex].
A relation R on a set A is called transitive relation if [tex](a,b)\in R[/tex] and [tex](b,c)\in R[/tex] then [tex](a,c)\in R[/tex] for all [tex]a,b,c\in A[/tex].
So, the relation R is a transitive relation because if a line [tex]l_1[/tex] s parallel to the line [tex]l_2[/tex] and the line [tex]l_2[/tex] is parallel to the line [tex]l_3[/tex] then the always line [tex]l_1[/tex] is parallel to the line [tex]l_3[/tex].
Therefore the relation R is a reflexive, symmetric and transitive relation.

42 = 16
43 - 64
Answer: 44 equals 128
Step-by-step explanation: This is because you do 16 times 4 to get 64, then you double that to 8, so you do 16 times 8 and get your answer 128

D) 101.31°
9514 1404 393
Answer:
A) 63.43°
Step-by-step explanation:
The two vectors in polar form are ...
u = (√(9²+6²))∠arctan(-6/9) = √117∠-33.69°
v = (√(7²+4²))∠arctan(4/7) = √65∠29.74°
The angle between the two vectors is ...
29.74° -(-33.69°) = 63.49°

Suppose that only 2 percent of all people are geniuses. If an IQ test indicates that Albert is a genius, but the test is only accurate 90 percent of the time, then the probability that Albert really is a genius is roughly:
Answer:
P = 1,8 %
Step-by-step explanation:
From the whole population, only 2% are geniuses. But test results, are accurate 90 %. So the probability that Albert really is a genius is:
P = 0,02 * 0,9
P = 0,018 or P = 1,8 %

Which phrase best describes taxable income?
Answer:
The correct answer is D.
Step-by-step explanation:
Taxable income is the income that is reached by taxes established by the government, that is, those sums of money from individuals that the government levies with a tax contribution. The so-called deductions are deducted from these sums, with which the apportionment between taxable income and deductions results in the final amount of taxes to be paid.

You and 3 friends are going to the County Fair.
You have a coupon that will save your group
$20. If the total bill to get into the fair was
$100, how much does one regular price ticket
to the fair cost?

Answer:
One regular price ticket cost $40
Step-by-step explanation:
First yo would have to add back the $20 that they saved to the total which would be $120 total and then since that was the total for all 3 of them you would do $120 divided by 3 which would be $40 for each ticket regularly.

Why would the volumes of the two figures be the same?
Answer:
They would sill be the same because just because the other shape is lopsided doesn't mean its different than the other. They can me moved left or right but they will still have the same volume.
Step-by-step explanation:
As 3D shearing transformations preserves the volume of figure, the volumes of the two figures would be the same.
What is shearing transformation in geometry?"Shearing is the process of slanting a three- dimensional geometrical object in 3-D space either in x, y, or in the z-direction."
For given example,
We can observe that figure 2 is a result of shearing transformation on figure 1.
We know, a three-dimensional shearing transformation preserves the volume of solid figures.
This means, the volume of both the figures is same.
Also, we can observe that the length, width and height of the both figures are equal.
Therefore, the volumes of the two figures would be the same.

Find missing side round to nearest tenth
Answer:
x = 9.9 or 10
Step-by-step explanation:
to find missing angle -->
90 + 61 + z = 180
151 + z = 180 *subtract 151 from both sides*
z = 29
to find x -->
tan (29) = x/18 *put tan(29) over 1 then cross multiply*

You want to open a checking account at your local bank which offers two options. A standard checking account charges $6 each month plus $.25 for each check written. A select checking account charges $4.50 each month plus $.50 for each check written. Which system of equations can be used to determine the number x of checks that must be written in a month in order for the total charges y for the two checking accounts to be the same?
Answer:
The total charges for the two checking accounts will be the same after 6 checks written.
Step-by-step explanation:
Since I want to open a checking account at my local bank which offers two options, a standard checking account that charges $ 6 each month plus $ 0.25 for each check written, and a select checking account that charges $ 4.50 each month plus $ 0.50 for each check written, to determine which system of equations can be used to determine the number X of checks that must be written in a month in order for the total charges Y for the two checking accounts to be the same, the following calculation must be performed:
6 + 0.25X = Y
4.5 + 0.5X = Y
6 + 0.25x5 = Y
4.5 + 0.5x5 = Y
6 + 1.25 = Y = 7.25
4.5 + 2.50 = 7
6 + 0.25x6 = Y
4.5 + 0.5x6 = Y
6 + 1.50 = Y = 7.50
4.5 + 3 = 7.50
Therefore, the total charges for the two checking accounts will be the same after 6 checks written.

Circle O and circle P are congruent. What can you conclude from the diagram?
Answer:
We can only infer that OA=OB=PD=DE.
Step-by-step explanation:
Since, if two circles are congruent then their radius must be equal.
And, here A and B are the points in the circumference of circle O therefore, the distance of these points from the center O of the circle is the radius of the circle.
So, OA=OB. ( if we join the points O and C then OA=OB=OC)
Similarly, In Circle P, PE= PD. ( if we join the points P and CF then PD=PE=PF).

El sueldo de los trabajadores de una multinacional sigue una distribución normal con media µ=$2000 y una desviación estándar σ=$600. Si se tomó una muestra de 64 trabajadores, calcular el intervalo de confianza para estimar el sueldo medio poblacional de los trabajadores, con un nivel de confianza del 99%.
Answer:
El intervalo, con un nivel de confianza de 99%, para estimar el sueldo medio poblacional de los trabajadores es de ($1807, $2193).
Step-by-step explanation:
El primero paso es el encuentro de lo [tex]\alpha[/tex], que es la subtracion de 1 por lo nivel de confianza e divididos por 2. Entonces:
[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]
Ahora, buscamos a z en la tabela Z de manera que z tienga uno p-value de [tex]1 - \alpha[/tex].
Entonces, z con uno p-value de [tex]1 - 0.005 = 0.995[/tex], o sea, z = 2.575.
La margen de error es:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
En que [tex]\sigma[/tex] es la desviación estándar y n es el tamaño de la muestra.
σ=$600. Si se tomó una muestra de 64 trabajadores
Entonces [tex]\sigma = 600, n = 64[/tex]
Margen de error:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]M = 2.575\frac{600}{\sqrt{64}}[/tex]
[tex]M = 193[/tex]
El limite inferior es la subtración de la media de la muestra por la margen de error. Entonces 2000 - 193 = $1807.
El limite inferior es la suma de la media de la muestra con la margen de error. Entonces 2000 + 193 = $2193.
El intervalo, con un nivel de confianza de 99%, para estimar el sueldo medio poblacional de los trabajadores es de ($1807, $2193).
