No, it is not possible for a binary relation to be both symmetric and antisymmetric because a relation cannot be both symmetric and antisymmetric unless it is the empty relation, as the properties of symmetry and antisymmetry contradict each other for non-empty sets.

A relation is symmetric if for any elements x and y in the set, if (x,y) is in the relation, then (y,x) is also in the relation. This means that the relation is symmetric around the diagonal.

On the other hand, a relation is antisymmetric if for any elements x and y in the set, if (x,y) is in the relation and (y,x) is in the relation, then x=y. This means that the relation is asymmetric around the diagonal.

If a relation is both symmetric and antisymmetric, then it means that for any elements x and y in the set, if (x,y) is in the relation, then (y,x) is also in the relation, and x=y. This implies that the relation is only defined on pairs of identical elements, and therefore it is the diagonal relation, which is reflexive, symmetric, and antisymmetric.

In summary, the only binary relation that is both symmetric and antisymmetric is the diagonal relation, which is defined as {(x,x) : x is an element of the set}.

The probability that your partner has the other three aces given that you have one ace is approximately 0.000037 or 0.0037%. This is a very low probability, so it is unlikely that your partner has the other three aces.

We can use Bayes' theorem to solve this problem. Let A be the event that your partner has the other three aces, and B be the event that you have one ace. Then we want to find P(A|B), the probability that your partner has the other three aces given that you have one ace.

Using Bayes' theorem, we have:

P(A|B) = P(B|A) * P(A) / P(B)

We know that P(B|A) is 1/3, since your partner must have all three aces if you have one ace. We also know that P(A) is the probability that your partner has all three aces in a randomly dealt hand of 39 cards (52 cards - 13 cards dealt to you), which is:

P(A) = (4/39) * (3/38) * (2/37) = 0.000038

To find P(B), the probability that you have one ace, we can use the law of total probability:

P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)

The probability that you have one ace given that your partner has all three aces is zero, so P(B|not A) is the probability of getting exactly one ace in a hand of 39 cards:

P(B|not A) = (4/39) * (35/38) * (34/37) * (33/36) * ... * (28/16) * (24/15) * (23/14) * (22/13) = 0.03833

where we multiply the probabilities of not getting an ace (35/38, 34/37, etc.) by the probability of getting an ace (4/36) for each card dealt after the first ace.

We also know that P(not A) is the complement of P(A), which is 1 - P(A).

Putting it all together, we have:

P(A|B) = (1/3) * (0.000038) / [ (1/3) * (0.000038) + (2/3) * (0.03833) ]

Simplifying, we get:

P(A|B) = 0.000037

So the probability that your partner has the other three aces given that you have one ace is approximately 0.000037 or 0.0037%. This is a very low probability, so it is unlikely that your partner has the other three aces.

Step-by-step explanation:

The given function is decreasing on the interval (-1, 3/2).

To determine the intervals on which a function is decreasing, we need to find the values of x for which the function's derivative is negative. If the derivative is negative, then the function is decreasing.

Let's consider each option:

A. (–[infinity], –1) ∪ (0,[infinity])

To find the derivative of the function, we first need to find the function itself. Without knowing the function, we cannot determine the derivative or the intervals on which it is decreasing.

B. (1, [infinity])

Again, we need to know the function to determine its derivative and the intervals on which it is decreasing.

C. (–[infinity], –1) ∪ (1, [infinity])

Similarly, we need to know the function to determine its derivative and the intervals on which it is decreasing.

D. (–1, 0)

Let's assume the function is f(x). To find its derivative, we can use the power rule of differentiation, which states that if f(x) = x^n, then f'(x) = nx^(n-1).

If the given function is decreasing on the interval (-1, 0), then its derivative, f'(x), must be negative on that interval. Therefore, we can set up the inequality f'(x) < 0 and solve for x.

Let's first find the derivative of the function:

f(x) = x^2 - 3x + 2

f'(x) = 2x - 3

Now we can set up the inequality:

2x - 3 < 0

Solving for x, we get:

x < 3/2

So the function is decreasing on the interval (-1, 3/2).

We can express the vector 18 as v = VC + VN =

To express the vector 18 in the form v = VC + VN with VC in the row space C(AT) and VN in the null space N(A), we need to first find the components of v in both spaces.

The basis for the row space is given as {2, 3, 3, 0, 2}, we can use these vectors as rows to form a matrix C. We then compute the orthogonal complement of C, which gives us the null space of A.

We can find that the row space C(AT) is spanned by the basis vectors {2, 3, 3} and the null space N(A) is spanned by the basis vector {0, -2, 1, 0, 0}.

To express the vector 18 as a sum of a vector in C(AT) and a vector in N(A), we first project v onto the row space C(AT) using the formula VC =

[tex](C(AT)C)^(-1)C(AT)v[/tex]

This gives us VC =

The total percent composition for all the elements in the compound CgH10N402 is 61.73%.

To calculate the molecular mass of CgH10N402, we need to add up the atomic masses of all the atoms in the compound. The atomic masses can be found on the periodic table.

The molecular formula indicates that the compound contains:

1 carbon atom (C) with atomic mass of 12.01 g/mol

10 hydrogen atoms (H) with atomic mass of 1.01 g/mol

1 nitrogen atom (N) with atomic mass of 14.01 g/mol

4 oxygen atoms (O) with atomic mass of 16.00 g/mol

Molecular mass (M) = (1 x 12.01) + (10 x 1.01) + (1 x 14.01) + (4 x 16.00) = 162.14 g/mol

Therefore, the molecular mass for the compound CgH10N402 is 162.14 g/mol.

To determine the percent composition of each element in the compound, we need to divide the mass contribution of each element by the total molecular mass and multiply by 100%.

Percent composition of C:

Mass contribution of C = 1 x 12.01 g/mol = 12.01 g/mol

% C = (12.01 g/mol / 162.14 g/mol) x 100% = 7.41%

Percent composition of H:

Mass contribution of H = 10 x 1.01 g/mol = 10.10 g/mol

% H = (10.10 g/mol / 162.14 g/mol) x 100% = 6.23%

Percent composition of N:

Mass contribution of N = 1 x 14.01 g/mol = 14.01 g/mol

% N = (14.01 g/mol / 162.14 g/mol) x 100% = 8.63%

Percent composition of O:

Mass contribution of O = 4 x 16.00 g/mol = 64.00 g/mol

% O = (64.00 g/mol / 162.14 g/mol) x 100% = 39.46%

Therefore, the percent composition for the element C, H, N, O in the compound CgH10N402 are:

%C = 7.41%

%H = 6.23%

%N = 8.63%

%O = 39.46%

The total percent composition for all the elements in the compound must add up to 100%.

Total percent composition = %C + %H + %N + %O = 7.41% + 6.23% + 8.63% + 39.46% = 61.73%

Therefore, the total percent composition for all the elements in the compound CgH10N402 is 61.73%.

Arranging them in ascending order, we get:
X1 = -0.007
X2 = 0
X3 = 0

To find the characteristic polynomial of A, we first need to compute the determinant of (A - λI), where I is the identity matrix and λ is a scalar variable:

|0-λ  0.00 0.007|
|0.00 0-λ  0.00 |
|0.00 0.00 0-λ  |

Expanding along the first row, we get:

       |0.00 0-λ |            |0.0 0.00|                 |0.00 0-λ |

Simplifying, we obtain:

-λ³ + (-0.007)λ² = 0

Factoring out λ², we get:

λ²(-λ - 0.007) = 0

Therefore, the characteristic polynomial of A is:

p(A) = λ³ + 0.007λ²

To find the eigenvalues of A, we need to solve the equation p(A) = 0. We can see that one of the roots is λ = 0, which has multiplicity 2 (since it appears as a factor of λ² in the characteristic polynomial). To find the third eigenvalue, we need to solve:

λ³ + 0.007λ² = 0

Factoring out λ² again, we obtain:

λ²(λ + 0.007) = 0

Therefore, the remaining eigenvalue is λ = -0.007. Thus, the eigenvalues of A are:

The cash payment equivalent to making monthly payments of $1074 for 5 years with an interest rate of 11% per annum compounded semi-annually is $49,701.

To find the cash payment, we can use the Present Value of the Annuity formula:

PV = PMT * [(1 - (1 + r)⁻ⁿ) / r]

Where:
PV = Present Value (cash payment)
PMT = Monthly payment ($1074)
r = Monthly interest rate
n = Number of payments (5 years * 12 months = 60)

First, we need to find the monthly interest rate. Since the interest is compounded semi-annually, we'll divide the annual interest rate by 2, and then convert it to a monthly rate:

Semi-annual interest rate = 11% / 2 = 5.5% = 0.055
[tex](1 + 0.055)^{(1/6)} - 1[/tex] ≈ 0.008944 (rounded to 6 decimal places)
