None of the above.
Option D is the correct answer, intervals of the coefficients are- b ∈ (2.1, 5.3], c ∈ (-3, 10), and d ∈ (-138, -126].
Here, we are given a polynomial of the form [tex]x^{3}[/tex] + b[tex]x^{2}[/tex] + cx + d
The zeroes of the polynomial are ( -4 + 4i ) and 4
The third root of the cubic equation will be (-4 - 4i) which is the conjugate of (-4 + 4i)
This means that for x = ( -4 + 4i ), ( -4 - 4i ) and 4, the polynomial is equal to 0.
Further, the sum of zeroes of a cubic equation
= -(coefficient of [tex]x^{2}[/tex] )/(coefficient of [tex]x^{3}[/tex])
Thus, -4 + 4i + 4 - 4 - 4i = -b
b = 4
Similarly, the sum of the product of zeroes taken 2 at a time = c
⇒ (-4 + 4i)(-4- 4i) + 4(-4 + 4i) + 4(-4- 4i) = c
c = 16 -16[tex]i^{2}[/tex] - 16 + 16i - 16 - 16i
c = 16 + 16 - 32
c = 0
Further, product of zeroes = -d
-d = (-4 + 4i) (-4- 4i) 4
d = -(16 + 16i - 16i -16[tex]i^{2}[/tex]) 4
d = -(16 + 16)4
d = -128
Thus, we get that option D is the correct answer, intervals of the coefficients are- b ∈ (2.1, 5.3], c ∈ (-3, 10), and d ∈ (-138, -126].

What does dilated by a scale factor of 3 mean?.
How do you know if a system has one solution or infinitely many?.
If you try to solve an equation and receive a variable or a number equal to itself, the problem has an unlimited number of solutions.
There are an infinite number of solutions to the equation system when two lines coincide with the same y-intercept. If the slope and y-intercept of the two lines coincide, they actually belong to the same line. Although a system of linear equations typically has a single solution, it occasionally may have infinite or no solutions (parallel lines) (same line). When the two lines that make up a linear system cross each other once, the system has a single solution. When the two lines are identical, as in the cases of y=x+3 and 2y=2x+6, a linear system has several (infinite) solutions. When the lines never cross (i.e., they are parallel and have the same slope), a linear system cannot be solved.

Answer:
shaded area
unlikely
Step-by-step explanation:
She should guess a shaded portion of a rectangle that has a height of 10 and a length of 8 to maximize her chances of winning. The unlikely word describes the likelihood of the ball stop.
First, we need to find the areas of all the regions.
The area of the shaded rectangle = Length x Breadth = 10 x 8 = 80 square units
Area of unshaded rectangle = Length x Breadth = 5 x 2 = 10 square units
Area of unshaded triangle = 1/2 x base x height = 1/2 x 4 x 8 = 32/2 = 16 square units
Area of unshaded square = Side^2 = 4^2 = 16 square units
The area difference between the shaded and unshaded areas = The area of the shaded rectangle - (Area of unshaded rectangle + Area of unshaded triangle + Area of the unshaded square)
The area difference between the shaded and unshaded areas = 80 - (10 + 16 + 16)
The area difference between the shaded and unshaded areas = 80 - 42 = 38
As we see that the area of the shaded region is 38 more than the unshaded region so to maximize her chances of winning she should guess the shaded region or area.
Probability percentage of the shaded rectangle = 80/122 x 100 = 65.57%
Probability percentage of an unshaded rectangle = 10/122 x 100 = 8.20%
Probability percentage of an unshaded triangle = 16/122 x 100 = 13.11%
Probability percentage of an unshaded square = 16/122 x 100 = 13.11%
The unlikely word describes the likelihood of the ball stopping in a square or rectangular-shaped area because one is shaded and unshaded and the other is only unshaded. So, both are having different probabilities because of shape, area, and portion.

consider a blackbody of surface area a that cools down with time according to the time-dependent tem- perature function t(t)
The blackbody surface area cools down the area according to time dependent temperature (t)
Radiation that is incident on an object is partially absorbed and partially reflected. At thermodynamic equilibrium, the rate at which an object absorbs radiation is the same as the rate at which it emits it.
Therefore, a good absorber of radiation - any object that absorbs radiation, is also a good emitter. A perfect absorber absorbs all electromagnetic radiation incident on it; such an object is called a blackbody.
The temperature (T) of the object that emits radiation, or the emitter, determines the wavelength at which the radiated energy is at its maximum. For example, the Sun, whose surface temperature is in the range between 5000 K and 6000 K, radiates most strongly in a range of wavelengths about 560 nm in the visible part of the electromagnetic spectrum. The body, when at its normal temperature of about 300 K, radiates most strongly in the infrared part of the spectrum.

If banks' desired reserve/deposit ratio is 25.0 percent, deposits in macro land are $28800000 and the money supply is $36000000
The deposit ratio is the rate sum of money (stores) that commercial banks must not loan out or invest, the reserve ratio is as a rule fixed by the central banks to control inflation and the volume of cash in circulation inside a given country in a particular time.
Initial bank deposit= 60% of 12000000 = 7200000, The reserve/deposit will calculate as follows (25.0 /100%)=0.25 and If banks desired to keep 25.0 it deposit ratio will be : 1/0.25*7200000= 28800000

let v be a finite-dimensional vector space. let t : v !v be a linear transformation. if for each eigenvalue of t , the geometric multiplicity is equal to the algebraic multiplicity, then t is diagonalizable.
The geometric multiplicity is equal to the algebraic multiplicity, then t is diagonalizable.
The word "nilpotent" is missing from the title, rather confusing, since being nilpotent is easily seen to be the only possible obstruction against being diagonalisable for a rank 1 operator. After all, by rank-nullity this implies the nullity equals n−1, and this is (by definition) the dimension of the eigenspace for 0. Also Im(T) is always T-stable, so being of dimension 1 its nonzero vectors are eigenvectors, and if this is for a nonzero eigenvalue λ, then the eigenspaces for 0 and for λ are complementary, and so T is diagonalisable.
So the only thing that can go wrong is that the nonzero vectors of Im(T) are eigenvectors for 0, but then clearly T2=0 so T is nilpotent.
It would have been a bit more fun if instead of T not being nilpotent it had been given that T has nonzero trace. Since 0 is a root of the characteristic polynomial χT with multiplicity at least n−1 (which is its geometric multiplicity), the "final" root of χT equals the sum of all its roots, which is the trace of T. This is also the eigenvalue of nonzero vectors in Im(T), and as we have seen it is zero if and only if T is nilpotent if and only if T is not diagonalisable.
Hence the answer is the geometric multiplicity is equal to the algebraic multiplicity, then t is diagonalizable.

Step-by-step explanation:
What is the scale factor of the dilation triangle ABC was dilated and translated to form similar triangle ABC?.
2.5 is the scale factor of the dilation triangle ABC was dilated and translated to form similar triangle A'B'C'
Given,
Triangles ABC and A'B'C' are similar
For ABC;- (x₁, y₁) = (0, 2) and (x₂, y₂) = (2, 2)
For A'B'C' ;- (x₁, y₁) = (-4, -1) and (x₂, y₂) = (1, -1)
We have to find the scale factor of the dilation;
Here,
Find the distance AB and distance A'B' with the formula
Distance, d = [tex]\sqrt{(y_{2} -y_{1})^{2} +(x_{2} -x_{1} )^{2} }[/tex]
Then,
a) Distance of AB
d AB = [tex]\sqrt{(2-2)^{2}+(2-0)^{2} }[/tex]
d AB = [tex]\sqrt{0^{2} +2^{2} }[/tex]
d AB = √4
Distance of AB = 2 units
b) Distance of A'B'
d A'B' = [tex]\sqrt{(-1+1)^{2} +(1+4)^{2} }[/tex]
d A'B' = [tex]\sqrt{0^{2} +5^{2} }[/tex]
d A'B' = √25
Distance of A'B' = 5 units
Now,
Scale factor;
Scale factor = Distance of AB / Distance of A'B'
Scale factor = 5/2
Scale factor = 2.5
Therefore,
2.5 is the scale factor of the dilation triangle ABC was dilated and translated to form similar triangle A'B'C'

The probability of a randomly selected adult having a rare disease for which a diagnostic test has been developed is 0.002. The diagnostic test is not perfect. The probability the test will be positive (indicating that the person has the disease) is 0.96 for a person with the disease and 0.01 for a person without the disease. The proportion of adults for which the test would be positive is
The probability of contracting an illness is 0.0475.
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.The likelihood that an event will occur increases with its probability.A straightforward illustration is tossing a fair (impartial) coin.The chance of both outcomes ("heads" and "tails") is equal because the coin is fair, "heads" is more likely than "tails," there are no other conceivable outcomes, and the likelihood of either outcome is .According to our question-
D: The patient has the illness
ND: the individual without the disease
TD: The results of the test show the patient has the illness.
P(D) will therefore equal 0.001 since only 0.001 of the population is affected by the disease.
P(ND) = 0.991
Because the test successfully identifies a patient with the condition 99% of the time, P(TD/D) = 0.99.
P(TD/ND) = 0.02 because the test indicates that a healthy person contracts the disease 2% of the time.
We are seeking for P(D|TD) and P(ND|TD), respectively.
According to the Bayes formula, 0.00099/0.00099+0.01982 = 0.00099/0.02081 = 0.0475 = (0.99*0.001)/(0.99*0.001)+(0.02*0.991)
And, \s = 1 - \s = 1 - 0.0475 \s = 0.9525
Therefore,
The likelihood of having an illness is 0.0475.
The likelihood of not having any sick people is 0.9525.
Hence, The probability of contracting an illness is 0.0475.
