Step-by-step explanation:

Answer:

Step-by-step explanation:

If the roots of p(x) are a, b, c, then it factors as ...

  p(x) = (x -a)(x -b)(x -c)

and the expanded form is ...

  p(x) = x^3 -(a+b+c)x^2 +(ac +b(a+c))x -abc

The requirement that the coefficients match the roots means we have three equations in three unknowns:

  a = -(a+b+c)

  b = ac +b(a+c)

  c = -abc

The attachment shows the solutions to these equations. The solutions are found by making the substitutions ...

This leaves us with two equations in two unknowns that can be graphed on a Cartesian plane. The graph of the second equation is a circle:

  x(1 -a -y) -ay = 0   ⇒   (x +1)^2 +y^2 = 1

The graph of the first equation is the union of the line y=0 and two hyperbolas. The points of intersection between this graph and the circle are ...

  (x, y) = (-2, 0), (-1, -1), (0, 0)   ⇒   (a, b, c) = (1, -2, 0), (1, -1, -1), (0, 0, 0)

The three polynomials that correspond to these values are shown above and in the attachment.

Additional comment

There is an irrational fourth solution to the requirement that the roots match the coefficients.

The probability that k people will occupy k adjacent seats in a row with n seats (n > k) is (n-k+1) / (n choose k).

To find the probability that k people will occupy k adjacent seats in a row containing n seats, we can use the formula:

P = (n-k+1) / (n choose k)

Here, (n choose k) represents the number of ways to choose k seats out of n total seats. The numerator (n-k+1) represents the number of ways to choose k adjacent seats out of the n total seats.

For example, if there are 10 seats and 3 people, the probability of them sitting in 3 adjacent seats would be:

P = (10-3+1) / (10 choose 3)
P = 8 / 120
P = 0.067 or 6.7%

So the probability of k people occupying k adjacent seats in a row containing n seats is given by the formula (n-k+1) / (n choose k).

Answer:

x=20  and  x=-50

Step-by-step explanation:

To find the roots, we need to simply solve for x. We do this by first moving all of the terms to the left and setting the right side equal to 0.

-1000

x^2+30x-1000=0

Now, factor it.

What adds up to 30 but multiplies to get -1000?

-10 and 40? No, because they multiply to get -400.

-20 and 50? Yes, because they add up to 30 and multiply to get -1000.

(x-20)(x+50)

x-20=0

x=20

x+50=0

x=-50

So, the roots are x=20 and x=-50

Given :-

To Find :-

Solution :-

As we know that if the quadratic equation is in standard form which is ,

\( ax^2+bx + c =0\)

Then its roots are given by ,

\( x =\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\)

So on converting the equation in standard form ,

\( x^2+30x -1000=0\)

With respect to the standard form ,

Substitute in the Quadratic formula ,

\( x =\dfrac{-30\pm \sqrt{(30)^2-4(1)(-1000)}}{2(1)}\)

Simplify,

\( x =\dfrac{-30\pm\sqrt{900+4000}}{2}\)

Add the numbers inside square root ,

\( x =\dfrac{-30\pm\sqrt{4900}}{2}\)

Divide each term in numerator by 2,

\( x =\dfrac{-30}{2}\pm\dfrac{\sqrt{70^2}}{2}\)

Simplify ,

\( x = -15 \pm 35 \)

Separate the two solutions ,

\( x = -15 + 35 , -15 -35\)

Simplify ,

\(x = 20 , -50 \)

Hence the solution of the equation are 20 and -50 .

The statements about the clock are accurate are;

1.  Note that the face of a clock is divided into 12 equal parts and the Angle of each part is= 30°

If one hand points at 2 and the other points at 4, then it is divided into two parts that is 2 to 3 and 3 to 4.

The angle that will be formed then will be = 2 (30) = 60°

So therefore option one is correct

111. When a person place one hand at 5 and the other hand at 10, then it is divided into 5 parts.

The angle that is formed= 30(5) = 150°.

Therefore, the arc length =(37.68) = 15.7.

So therefore, Option three is correct.

V.  When the length of the minor arc ranges from 11 to 2, then this is divided is 3 parts.

So therefore, 3(30) = 90°  

The minor arc is said to ranges from 7 to 10 and it is represented by  3(30) = 90°

To further elaborate, let's break it down into three paragraphs. In the first paragraph, we can establish that points a and b are situated in a specific region of space. This region has a uniform electric field that is characterized by its direction and strength. Since there is no mention of the magnitude of the electric field, we can assume that it is constant throughout the region. This means that the electric field does not vary in strength from point to point, but remains the same across the entire region.

In the second paragraph, we can focus on the components of the electric field. Here, we learn that the electric field has no x or z-component, which means that it is purely directed along the y-axis. This also means that the electric field lines are parallel to the y-axis and are evenly spaced throughout the region. We can visualize the electric field as a series of equally spaced, parallel lines that extend indefinitely along the y-axis.

In the third and final paragraph, we can summarize the main points of the answer. We know that points a and b are in a region of space with a uniform electric field that has no x or z-component, but only a y-component. This means that the electric field is directed purely along the y-axis and is constant throughout the region.

The level of measurement that is appropriate for a classification where students are asked to rank their professors as good, average, or poor is the ordinal level of measurement.

Ordinal level of measurement is a statistical measurement level.

It involves dividing data into ordered categories.

For instance, when asked to rank teachers as good, average, or poor, the students' rating of the teachers falls under the ordinal level of measurement.

The fundamental characteristic of ordinal data is that it can be sorted in an increasing or decreasing order.

The numerical values of the categories are not comparable; instead, the categories are arranged in a specific order.

The ordinal level of measurement, for example, provides the order of the data but not the size of the intervals between the ordered values or categories.

The correct option is B "Models n independent replications of a Bernoulli experiment each with a probability p of success".

It is a frequency distribution of the number of successful outcomes that could occur in a set number of trials with an equal chance of success. In probability theory and statistics, the discrete probability distribution of the number of successes in a series of n independent experiments, each asking a yes-or-no question and each with its own Boolean-valued outcome: success or failure, is known as the binomial distribution with parameters n and p. When each trial has the same probability of achieving a given value, the number of trials or observations is summarized using the binomial distribution. The probability of observing a specific number of successful outcomes in a specific number of trials is determined by the binomial distribution.

What is residual?

A residual in statistics is the discrepancy between an observed value and a value that was predicted.

Typically, the anticipated value is based on a model, like a linear regression model. The prediction error is represented by a residual, which can be either positive or negative. A positive residual indicates a difference between the observed and expected values, whereas a negative residual indicates the opposite. Specifically, the residual's absolute value is the distance between the observed value and the predicted value.

For evaluating a model's correctness, residuals are crucial. The residuals should be randomly distributed in the vicinity of zero if the model is valid. The residuals will be biased either in favor of or against the null hypothesis if the model is not accurate. A model's goodness of fit can also be evaluated using the residual. Relatively small residuals characterize a model with a high goodness of fit. Remainders that are far from zero will be present in a model with a low goodness of fit.

Step-by-step explanation:

6a=54

a=54/6

a=9

Answer:

Option C.

Step-by-step explanation:

We know that, for a value a > 1.

if b > c, then:

a^b > a^c

Now, this means that if we have two functions:

f(x) = x^n

g(x) = x^m

and m > n

then for large values of x, g(x) will be larger than f(x), because g(x) has a larger exponent.

now, is also true that:

f(x) = x^n

g(x) = n^x

for n > 1

For large values of x, g(x) will be larger than f(x), again, because for larger values of x g(x) will have a really large exponent, thus it grows really fast.

Then we can conclude that for the functions:

f(x) = 3*x

g(x) = 3*x^2

h(x) = 2^x

For a given value of x, h(x) will exceed the other two functions.

This can be seen in the graph below, where:

h(x) is purple, g(x) is blue, and f(x) is green.

We can see that eventually, h(x) exceeds the other two.

The correct option is C.

The wrong with following piece of mRNA, TACCAGGATCACTTTGCCA is that it contains T and not U. So, option(D) is right choice here.

Messenger RNA (mRNA) is present in DNA. DNA uses four bases in its code, adenine (A), guanine (G), cytosine (C) and thymine (T). RNA also uses four bases. However, instead of using "T" as DNA, it uses uracil (U). So, if your DNA sequence is 3' T C G T T C A G T 5', the mRNA sequence would be 5' A G C A A G U C A 3'. A strand of DNA is a template strand that has a nucleotide sequence on it that is read by RNA polymerases. Rna polymerase reads the template strand and encodes the m-RNA using the base-pairing rule. According to the rule, adenine pairs with thymine and guanosine with cytosine. So if the template DNA reads TAC GTT ACG, RNA polymerase will read it as AUG CAA UGC. Since no thymine is present in RNA, it will code for U instead of T.

b. To find the probability a customer who ordered pancakes came to thediner late, we need to look at the intersection of the "pancakes" row and the "late" column. This gives us a probability of 0.1, or 10%

c. To determine whether breakfast choice and meal time are independent, we need to see if the probability of one event changes based on the occurrence of the other event. In this case, it seems that breakfast choice and meal time are not independent, as the probability of being late seems to differ based on what breakfast item the customer chose. For example, the probability of being late is higher for customers who ordered pancakes compared to those who ordered cereal. Therefore, the choice of breakfast item appears to be related to the probability of being late, and so breakfast choice and meal time are not independent.
