The equation is x² - 7x+11 is in form of quadratic equation ax²+bx+c where a = x² , b = -7 and c = 11 .
Option B is correct.
How do quadratic equations work?Quadratic equations are second-degree algebraic expressions with the form ax² + bx + c = 0. The word "quadratic" comes from the word "quad," which means square. To put it another way, an "equation of degree 2" is a quadratic equation. Numerous situations call for the use of a quadratic equation.
Evaluating :Factoring x²-7x+11
The first term is, x² its coefficient is 1 .
The middle term is, -7x its coefficient is -7 .
The last term, "the constant", is 11
x² - 7x + 11 = 0
Why do we use quadratic equations?When two things are multiplied together and both depend on the same variable, quadratic equations are frequently used. A quadratic equation is used, for instance, when working with area when both dimensions are written in terms of the same variable.

Fill in the P(X=x) values in the table below give a legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6.
The legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6 is: P(X=0) = 0.2, P(X=3) = 0.2, P(X=4) = 0.3, P(X=5) = 0.2, and P(X=6) = 0.1.
For a probability distribution to be legitimate, the probabilities of all the possible values of a random variable need to add up to 1. So, in this case, the sum of all the probabilities must be equal to 1.
For the given values, we can assign the probability of 0.2 to the values 0 and 3, 0.3 to the value 4 and 0.1 to the value 6, so that the sum of all the probabilities is 1.
Therefore, the legitimate probability distribution for the given discrete random variable X is as follows:
| Value (x) | P(X=x) |
|---|---|
| 0 | 0.2 |
| 3 | 0.2 |
| 4 | 0.3 |
| 5 | 0.2 |
| 6 | 0.1 |
The legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6 is: P(X=0) = 0.2, P(X=3) = 0.2, P(X=4) = 0.3, P(X=5) = 0.2, and P(X=6) = 0.1.

Which triangles could not be similar to triangle ABC?
4cm, 3cm, 5cm
If the ratio of their corresponding sides are identical, then the triangles are similar to each other. Triangle ABC, GHI and JKL have similar ratio of their corresponding sides. Thus, Triangle ABC,JKL and GHI are similar to each other.
It is not necesary that sides are equal in similar triangles but it is mandatory to have all the angles are identical in similar triangles.
If the length of corresponding sides of the triangle are in the same proportion then the triangles are similar to each other.
Therefore,
Sides of the triangle ABC and triangle GHI are in proportion, hence both the triangles are similar to each other.
Sides of the triangle ABC and triangle JKL are in proportion, hence both are similar to each other.

Automobiles arrive at a vehicle equipment inspection station according to a Poisson process with rate of alpha =10 hour. Suppose that with probability .5 an arriving vehicle will have no equipment violations. a., What is the probability that exactly ten arrive during the hour and all ten have no violations? b. What is the probability that ten "no-violation" cars arrive during the next hour?
In both cases, the probability would be 0.0045%.
What is Poisson's distribution?
The Poisson distribution is used to model the number of times an event occurs within a given time interval with a known average rate of occurrence. The probability of exactly k occurrences in a Poisson process is given by the equation:
P(k; λ) = (λ^k * e^-λ) / k!
Where λ is the average rate of occurrences and k is the number of occurrences.
a. In this case, the average rate of arrivals is alpha = 10 per hour, and the probability of no equipment violations is 0.5. The probability that exactly ten vehicles arrive during the hour and all ten have no violations is:
P(10; 10) * (0.5)^10 = 0.000045 or 0.0045%
b. The probability that ten "no-violation" cars arrive during the next hour is:
(10 * 0.5)^10 * e^(-10*0.5) / 10! = 0.000045 or 0.0045%
This probability is the same as in a. because it's the probability of exactly ten "no-violation" cars arriving during the next hour given that the number of cars arriving follows a Poisson distribution with an average rate of arrival of 10 per hour.
Hence, in both cases, the probability would be 0.0045%.

last digit of 2 to the power of 47
Answer:
2^1 = 2 -> last digit is 2
2^2 = 4 -> last digit is 4
2^3 = 8 -> last digit is 8
2^4 = 16 -> last digit is 6
2^5 = 32 -> last digit is 2
2^6 = 64 -> last digit is 4
2^7 = 128 -> last digit is 8
We can observe that the last digit follows a pattern of 2,4,8,6,2,4,8 and repeat.
Therefore, 2 to the power of 47 will have the same last digit as 2 to the power of (47 modulo 4) + 3

The amount of silk in some thread = 85%
Now,
Two equations are:
x + y = 75 _____(1)
x = 75 - y _____(2)
x + 0.85y = 0.94 x 75 _____(3)
Substituing (2) in (3)

What is Roman Republic?The highest ranked magistrate in the Roman Republic was known as a consul (consul in Latin). Two consuls, who were responsible for overseeing the state and, in particular, the army in the field, were chosen annually from among citizens over the age of forty-two for the office, which was annual and collegiate. The consuls, however, held relatively little power and influence during the foundation of the Empire because the emperor assumed the role of supreme leader, serving solely as a symbol of Republican Rome's past.
The Senate, also known as Senatus, de senex, elder, was one of the components of Ancient Rome's government. It was made up of 300 members drawn from the ancient magistrates during the most of the Republic, yet following Sila's dictatorship and during the imperial era, that number rose to 900.

prove that if p is a prime and g is a group of order p a for some a e z , then every subgroup of index p is normal in g. deduce that every group of order p 2 has a normal subgroup of order p.
A subgroup of index p must contain all elements of g, hence it is normal. Therefore, every group of order p2 has a normal subgroup of order p.
Let p be a prime and g be a group of order p a for some a ∈ Z.
First, we prove that every subgroup of index p is normal in g.
Since the order of g is p a , and the index of a subgroup of g is p, the subgroup must contain all elements of g. Thus, the subgroup is normal in g.
We can now deduce that every group of order p2 has a normal subgroup of order p.
Since the order of a group of order p2 is p2, we can divide it into two subgroups: one of order p, and one of order p. Since the subgroup of order p has an index of p, it must be normal in the group of order p2. Therefore, every group of order p2 has a normal subgroup of order p. Every group of order p2 has a normal subgroup of order p due to the fact that a subgroup of index p must contain all elements of g.

14 rows.
Step-by-step explanation:
It could be any amount, but there is a clear pattern that follows "-3". Starting from 51 and ending at 12, let's subtract by 3.
51, 48, 45, 42, 39, 36, 33, 30, 27, 24, 21, 18, 15, and 12.
There are 14 numbers; therefore, there are 14 rows.

Consider the graph of the polynomial function y=f(x) given below. The graph continues forever at both ends. Determine the following features (make sure you write all intervals in interval notation and all intercepts as points):
(A) State the domain and range.
(B) State the x-intercepts.
(C) State the y-intercept.
(D) State the interval(s) for which the function is increasing.
(E) State the interval(s) for which the function is decreasing.
(F) State the interval(s) for which the function is constant.
(G) State any symmetry about any axis and/or the origin.
(H) Determine whether the function is even, odd, or neither.
Answer:
(A)
Domain: [tex]\mathbf {(-\infty, \infty)}[/tex]
Range : [tex]\mathbf {(-\infty, \infty)}[/tex]
(B)
[tex](-2\sqrt{2} , 0) \;and\; (2\sqrt{2} , 0)[/tex]
(C)
(- ∞, -2] and [ 0, 2 ]
(D)
(- ∞, -2] and [ 0, 2 ]
(E)
[-2, 0 ] and [2, ∞ )
(F)
There is no interval where the function is constant
(G)
The graph is symmetric about the y-axis
(H)
This is an even function
Step-by-step explanation:
Warning!!
Pay careful attention to the use of two different brackets when using interval notation. A square bracket means the value next to it is included in that interval, a regular bracket indicates it is excluded
For example: [2, 4) means 2 is included but not 4
Pay careful attention to which bracket is being used where in my explanation and answers. You could lose points if you use the wrong brackets
(A)
Domain is the set of all x values that yield a real and defined value for y
Since the graph continues forever, the range of x values is -∞ to +∞
This is written as - ∞ < x < ∞ or, in interval notation as [tex]\mathbf {(-\infty, \infty)}[/tex]
Range is the set of y values for the given domain. Since the graph goes on forever, the range of y is - ∞ < y < ∞. Interval notation: [tex]\mathbf {(-\infty, \infty)}[/tex]
(B)
The x-intercepts are where the function graph crosses the x-axis. Mathematically, it is the value of x at y =
There are two x-intercepts:
[tex](-2\sqrt{2} , 0) \;and\; (2\sqrt{2} , 0)[/tex]
(C)
y-intercept is where the graph intersects the y-axis. Here the graph touches the y-axis at (0, 0).So y-intercept = (0,0)
(D)
The function is increasing in the intervals (- ∞, -2] and [ 0, 2 ]
(E)
The function decreases in the following intervals for values of x
[-2, 0 ] and [2, ∞ )
(F)
There is no interval where the function is constant
(G)
The graph is symmetric about the y-axis as you see visually. Mathematically, a graph is symmetric about the y axis if f(-x) = f(x)
Here we see that f(2) = 16 and f(-2) = 16 so there is y-axis symmetry
There is no symmetry about the x axis
To see if there is symmetry about the origin, replace any(x, y) with (-x, -y) and see if it is valid. (2, 16) replaced with (-2, -16) is not a point on the graph hence no symmetry about origin
(H)
This is an even function since it is symmetric about the y-axis

Purchases Transactions
Rolfes Company purchased merchandise on account
from Springhill Company for $12,200, terms 1/10, n/30.
Rolfes returned merchandise with an invoice amount of
$2,400 and received full credit.
a. If Rolfes Company pays the invoice within the
discount period, what is the amount of cash required for
the payment? If required, round the answer to the
nearest dollar.
b. What account is debited by Rolfes Company to record
the return?
?
Therefore , the solution of the given problem of percentage comes out to be the sum of money needed to complete the transaction is $7,722.
A percentage is defined.A percentage is mathematics is a figure or number that is stated as a proportion of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. However, the symbol "%" used to denote it is frequently used. The percentage amount is flat; there are no dimensions. Given that their numerator is 100, percentages are basically fractions.
Here,
According to the clauses 1/10, n/30, the buyer would receive a 1% reduction if the discount was applied within 10 days.
The consumer would be required to pay the whole amount in 30 days if the payment was not completed within this time frame.
Considering this and the fact that Nieman invoiced $2,400 for the returned goods, you must deduct this sum from their original purchase:
=> $12,200-$2,400= $7,800
Then, you must figure out the discount at 1% of $7,800 and deduct it from $7,800:
=> $7,800*1%= $78
=> $7,800-$78= $7,722
This means that, in the event Nieman Company settles the invoice during in the buy the product, the sum of money needed to complete the transaction is $7,722.

Suppose 3 < a < 7 and 5 < b < 9 Find all possible values of each expression
1.a+b
2.a-b
3.ab
4.a/b
The possible values for each expression are given as follows:
1. 8 ≤ a+b ≤ 16
2. -6 ≤ a - b ≤ 2
3. 15 ≤ ab ≤ 63
4. 1/3 ≤ a/b ≤ 7/5.
How to obtain the possible values of each expression?For the sum we have that:
The smallest value is assumed when a and b have the smallest values, hence a + b = 8.The largest value is assumed when a and b have the largest values, hence a + b = 16.For the subtraction, we have that:
The smallest value is assumed with highest b and lower a, hence: 3 - 9 = -6.The highest value is obtained with highest a and lowest b, hence: 7 - 5 = 2.For the multiplication we have that:
The smallest value is assumed when a and b have the smallest values, hence 3 x 5 = 15The largest value is assumed when a and b have the largest values, hence 7 x 9 = 63.For the division, we have that:
Lowest: a/b = 3/9 = 1/3.Higher: a/b = 7/5.More can be learned about expressions at https://brainly.com/question/723406
