If p2⟶r2 be defined by t(a0+a1x+a2x2)=(a0−a1,a1−a2), the matrix for t relative to the bases b={1+x+x2,1+x,x+x2} and b′={(1,2),(1,1)} is (0, -1). The matrix for T relative to the bases B = {1+x+x²,1+x, x+x²} and B′ = {(1, 2), (1, 1)} is [( -3, 1, -1), (2, 0, 1)].
Let T : P₂ → R² be defined by T(ao + a₁x + a₂x²) = (ao — a₁, a₁ - a₂). The matrix for T relative to the bases B = {1+x+x²,1+x, x+x²} and B′ = {(1, 2), (1, 1)}.The Matrix of a linear transformation can be found using the following formula.
[T]ᵇ'ᵇ = [I]ᵇ'ᵇ[T]ᵇ
Where [T]ᵇ'ᵇ is the matrix of T relative to B and B', [I]ᵇ'ᵇ is the matrix of identity transformation relative to B and B'. [T]ᵇ'ᵇ = [I]ᵇ'ᵇ[T]ᵇA) For the matrix of identity transformation relative to B and B', [I]ᵇ'ᵇ
We know that a matrix of identity transformation is an identity matrix.
Hence, [I]ᵇ'ᵇ = [1 0][0 1]B) For the matrix of T relative to B and B', [T]ᵇ'To find the matrix of T relative to B and B', we need to apply T on the elements of B to express the result in terms of B'.
T(1+x+x²) = (1, -1)T(1+x) = (1, 0)T(x+x²) = (0, -1)
The column vectors of the matrix [T]ᵇ'ᵇ will be the results of T on the elements of B, expressed in terms of B'. Hence,[T(1+x+x²)]ᵇ' = (-3, 2) = -3(1, 2) + 2(1, 1)[T(1+x)]ᵇ'
= (1, 0) = 0(1, 2) + 1(1, 1)[T(x+x²)]ᵇ'
= (-1, 1) = -1(1, 2) + 1(1, 1)
Therefore, [T]ᵇ'ᵇ = [( -3, 1, -1), (2, 0, 1)]

A Gallup poll conducted in November 2010 found that 493 of 1050 adult Americans believe it is the responsibility of the federal government to make sure all Americans have healthcare coverage.
Use Minitab Express to construct the following confidence intervals. Report your answers as decimals (not percents) rounded to three decimal places, where applicable.
a) We are 95% confident that the proportion of all adult Americans who believe it is the responsibility of the federal government to make sure all Americans have healthcare coverage is between ____ and ____
b) We are 99% confident that the proportion of all adult Americans who believe it is the responsibility of the federal government to make sure all Americans have healthcare coverage is between _____ and ____
The sample proportion is calculated by dividing the number of individuals who believe it is the responsibility of the federal government (493) by the total number of adult Americans surveyed (1050).
a) For the 95% confidence interval, we use the formula: Sample proportion ± Z * (Standard error). The value of Z is determined by the desired confidence level. In this case, for a 95% confidence level, Z is the critical value corresponding to a two-tailed test. By plugging in the values, we can calculate the lower and upper limits of the interval.
b) Similarly, for the 99% confidence interval, we use the same formula but with the appropriate critical value for a 99% confidence level.
Using Minitab Express or statistical tables, we can find the critical values and compute the confidence intervals.
Hence, the 95% confidence interval represents our level of confidence that the true proportion of adult Americans who believe it is the responsibility of the federal government to provide healthcare coverage lies within the reported interval. Similarly, the 99% confidence interval provides a higher level of confidence in capturing the true proportion.

The marginal PMFs for two INDEPENDENT random variables are given as follows 1/8 x = -1 Px(x) 1/2 = 0 3/8 1 = X = X = - py(y) = Py = 5/16 y=-1 9/16 y=0 1/8 = y = 1 a) Find the joint PMF for X, Y
The joint PMF for X, Y is given by the following table:
x\y 5/128 9/128 1/64 5/32 9/32 1/16 15/128 27/128 3/64
The joint probability mass function (PMF) of two discrete random variables is a function that maps each pair of outcomes of the random variables to a probability. In particular, the joint PMF gives the probability that the random variables take a certain pair of values on each trial. Therefore, we have to find the probability that the random variables X and Y take each of the six possible values.
Therefore, the joint PMF for X, Y is given as follows:
For x = -1 and y = -1,P(X = -1, Y = -1)
= P(X = -1)P(Y = -1)
= (1/8)(5/16)
= 5/128
For x = -1 and y = 0,P(X = -1, Y = 0) = P(X = -1)P(Y = 0)
= (1/8)(9/16)
= 9/128
For x = -1 and y = 1,P(X = -1, Y = 1) = P(X = -1)P(Y = 1)
= (1/8)(1/8)
= 1/64
For x = 0 and y = -1,P(X = 0, Y = -1) = P(X = 0)P(Y = -1)
= (1/2)(5/16)
= 5/32
For x = 0 and y = 0,P(X = 0, Y = 0) = P(X = 0)P(Y = 0)
= (1/2)(9/16)
= 9/32
For x = 0 and y = 1,P(X = 0, Y = 1) = P(X = 0)P(Y = 1)
= (1/2)(1/8)
= 1/16
For x = 1 and y = -1,P(X = 1, Y = -1) = P(X = 1)P(Y = -1)
= (3/8)(5/16)
= 15/128
For x = 1 and y = 0, P(X = 1, Y = 0) = P(X = 1)P(Y = 0)= (3/8)(9/16)
= 27/128
For x = 1 and y = 1,P(X = 1, Y = 1) = P(X = 1)P(Y = 1)
= (3/8)(1/8)
= 3/64
Therefore, the joint PMF for X, Y is given by the following table:
x\y 5/128 9/128 1/64 5/32 9/32 1/16 15/128 27/128 3/64

Step-by-step explanation:
The full weight of a brand of a pack of sweet potato fries is a random variable with µ = 350 g and σ= 4.1 8. Assume that you pick a random pack from the population.
a. Find the proportion of packs that contain less than 340 g?
b. How likely is it for a pack to contain 330 g?
The proportion of packs that contain less than 340g is approximately 0.0918 or 9.18%. The likelihood of a pack containing exactly 330g cannot be determined without additional information.
To find the proportion of packs that contain less than 340g, we need to calculate the z-score and use the standard normal distribution table. The Calculating z-score:
z = (x - µ) / σ
Where x is the value we want to find the proportion for (in this case, 340g), µ is the mean (350g), and σ is the standard deviation (4.18g).
Substituting the values, we have:
z = (340 - 350) / 4.18 ≈ -2.39
Next, we look up the corresponding z-score in the standard normal distribution table. The area to the left of -2.39 represents the proportion of packs that contain less than 340g. Consulting the table, we find that the area is approximately 0.0091 or 0.91%.
Therefore, the proportion of packs that contain less than 340g is approximately 0.0918 or 9.18%.
To determine the likelihood of a pack containing exactly 330g, we need more information. Specifically, we would need the probability density function (PDF) of the distribution to calculate the exact likelihood. Without the PDF, we cannot determine the likelihood of a specific weight like 330g.

Find the characteristic c using a 64-bit long real equivalent decimal number -147 with mantissa f = 0.1484375
Characteristic 'c' using a 64-bit long real equivalent decimal number -147 with mantissa 'f' = 0.1484375, the number can be expressed as -1.48 x 10^2. The characteristic 'c' is the exponent of the power of 10. Therefore, the characteristic 'c' is -2.
The scientific notation representation of a real number is given by 'm x 10^c', where 'm' is the mantissa and 'c' is the characteristic. In this case, we have a 64-bit long real equivalent decimal number -147 with mantissa 'f' = 0.1484375. The number can be written as -1.48 x 10^2.
To determine the characteristic 'c', we look at the exponent of the power of 10. In this case, the exponent is 2. However, since the number is negative, the characteristic is also negative. Therefore, the characteristic 'c' is -2.In summary, for the given number -147 with mantissa 0.1484375, the characteristic 'c' is -2.

Suppose that the average time a fully charged 6-volt laptop battery will operate a computer is 4.6 hours and follows the exponential probability distribution. Determine the following probabilities.
a) Determine the probability that the next charge will last less than 1.9 hours.
b) Determine the probability that the next charge will last between 2.9 and 4 hours.
c) Determine the probability that the next charge will last more than 5 hours.
(Round to four decimal places as needed.)
(a) 0.3694 is the probability that the next charge will last less than 1.9 hours. (b) 0.2344 is the probability that the next charge will last between 2.9 and 4 hours. (c) 0.3830 the probability that the next charge will last more than 5 hours.
To solve these probabilities, we need to use the exponential probability distribution formula. The formula for the exponential distribution is:
[tex]P(X \leq x) = 1 - e^{-\lambda x}[/tex]
where,
λ is the rate parameter, and
x is the variable representing the duration.
Given that the average time a fully charged 6-volt laptop battery will operate a computer is 4.6 hours, we can find the rate parameter (λ) by taking the reciprocal of the average:
λ = 1 / 4.6
Now let's calculate the probabilities:
a) Determine the probability that the next charge will last less than 1.9 hours.
Using the exponential distribution formula:
[tex]P(X \leq 1.9) = 1 - e^{(-\lambda \times 1.9)}[/tex]
[tex]P(X \leq 1.9) = 1 - e^{(-\frac{1}{4.6} \times 1.9)}[/tex]
[tex]P(X \leq 1.9) = 1 - e^{(-0.4130)}[/tex]
P(X ≤ 1.9) ≈ 0.3694 (rounded to four decimal places)
Therefore, the probability that the next charge will last less than 1.9 hours is approximately 0.3694.
b) Determine the probability that the next charge will last between 2.9 and 4 hours.
Using the exponential distribution formula:
P(2.9 ≤ X ≤ 4) = P(X ≤ 4) - P(X ≤ 2.9)
[tex]P(2.9 \leq X \leq 4) = [1 - e^{(-\lambda \times 4)}] - [1 - e^{(-\lambda \times 2.9)}][/tex]
[tex]P(2.9 \leq X \leq 4) = [1 - e^{(-\frac{1}{4.6} \times 4)}] - [1 - e^{(-\frac{1}{4.6} \times 2.9)}][/tex]
P(2.9 ≤ X ≤ 4) ≈ 0.2344 (rounded to four decimal places)
Therefore, the probability that the next charge will last between 2.9 and 4 hours is approximately 0.2344.
(c) Determine the probability that the next charge will last more than 5 hours.
Using the exponential distribution formula:
P(X > 5) = 1 - P(X ≤ 5)
[tex]P(X > 5) = 1 - [1 - e^{(-\lambda \times 5)}][/tex]
[tex]P(X > 5) = 1 - [1 - e^{(-\frac{1}{4.6} \times 5)}][/tex]
P(X > 5) ≈ 0.3830 (rounded to four decimal places)
Therefore, the probability that the next charge will last more than 5 hours is approximately 0.3830.
