b) If both f and g are one-to-one functions, then the composition f ○ g is also one-to-one.

c) If both f and g are onto functions, then the composition f ○ g is also onto.

a) The domain of the function f ○ g is the set of elements in A for which g(x) is defined. In other words, it is the set of all x in A such that g(x) belongs to the domain of f. The codomain of f ○ g is the set of elements in C, which is the codomain of f. It is the set to which the values of f ○ g belong.

b) To prove that the composition f ○ g is one-to-one, we need to show that if f ○ g(x₁) = f ○ g(x₂), then x₁ = x₂. Since f and g are one-to-one, if f(g(x₁)) = f(g(x₂)), it implies that g(x₁) = g(x₂). Now, since g is one-to-one, it follows that x₁ = x₂. Therefore, the composition f ○ g is also one-to-one.

c) To prove that the composition f ○ g is onto, we need to show that for every element y in the codomain of f ○ g, there exists an element x in the domain of f ○ g such that f ○ g(x) = y.

Since f is onto, for every element z in the codomain of f, there exists an element b in the domain of f such that f(b) = z.

Similarly, since g is onto, for every element b in the codomain of g, there exists an element a in the domain of g such that g(a) = b.

Combining these statements, for every element y in the codomain of f ○ g, there exists an element a in the domain of g such that f(g(a)) = y. Therefore, the composition f ○ g is onto.

Step-by-step explanation:

squaring both side

(18√8-8√18)^2=(√n)^2

(18√8)^2+(8√18)^2-(2)(8√18)(18√8)=n

after solving it we will get

3744-3456=n

n=288

=====================================================

Explanation:

Simplify the first part of the left side

\(18\sqrt{8} = 18\sqrt{4*2}\\\\18\sqrt{8} = 18\sqrt{4}*\sqrt{2}\\\\18\sqrt{8} = 18*2*\sqrt{2}\\\\18\sqrt{8} = 36\sqrt{2}\)

And do the same for the second part of the left side

\(8\sqrt{18} = 8\sqrt{9*2}\\\\8\sqrt{18} = 8\sqrt{9}*\sqrt{2}\\\\8\sqrt{18} = 8*3*\sqrt{2}\\\\8\sqrt{18} = 24\sqrt{2}\)

For each simplification, you are trying to factor the stuff under the square root so that you pull out the largest perfect square factor possible.

-------------------------

The original equation \(18\sqrt{8}-8\sqrt{18} = \sqrt{n}\) turns into \(36\sqrt{2}-24\sqrt{2} = \sqrt{n}\)

We have the common factor of \(\sqrt{2}\) so we can combine like terms on the left side ending up with \(12\sqrt{2}\)

-------------------------

So,

\(18\sqrt{8}-8\sqrt{18} = \sqrt{n}\\\\36\sqrt{2}-24\sqrt{2} = \sqrt{n}\\\\12\sqrt{2} = \sqrt{n}\\\\\sqrt{n} = 12\sqrt{2}\\\\\left(\sqrt{n}\right)^2 = \left(12\sqrt{2}\right)^2\\\\n = 288\)

Yes it is possible to express \(18\sqrt{8}-8\sqrt{18}\) as multiples of the same square root. In this case, we can express the left hand side of the original equation as 12 multiples of \(\sqrt{2}\)

Mr. Jones bought approximately 13 pamphlets.

In this problem, we have two types of items: books and pamphlets. Books cost 50¢ and pamphlets cost 15¢ at the book sale.

Let's use variables to represent the quantities we don't know. Let's say Mr. Jones bought x books and y pamphlets.

We are given two pieces of information:
1. Mr. Jones spent $90 on his purchases.
2. He bought 15 more pamphlets than books.

Now, let's set up the equations based on the given information.

First, let's consider the cost equation. The total cost of the books and pamphlets should equal $90.

The cost of x books is 50¢ * x, and the cost of y pamphlets is 15¢ * y. So, the equation becomes:
50x + 15y = 90

Next, let's consider the second piece of information. Mr. Jones bought 15 more pamphlets than books, which means y = x + 15.

Now, we have a system of two equations:
50x + 15y = 90
y = x + 15

To solve this system, we can use substitution or elimination method. Let's use substitution:

Substitute the value of y from the second equation into the first equation:
50x + 15(x + 15) = 90

Simplify the equation:
50x + 15x + 225 = 90
65x + 225 = 90

Subtract 225 from both sides:
65x = 90 - 225
65x = -135

Divide both sides by 65:
x = -135 / 65
x ≈ -2.08

Since we cannot have a negative number of books, we know that x must be a positive whole number. So, let's round x to the nearest whole number:
x ≈ -2

Now, substitute this value of x back into the second equation to find y:
y = x + 15
y ≈ -2 + 15
y ≈ 13

Therefore, Mr. Jones bought approximately 13 pamphlets.

Answer:

The answer is "180".

Step-by-step explanation:

Please find the complete question in the attached file.

Let's

x = ounces solution of A

y = ounces solution of B

Lucy has $7 less than Kristine and $5 more than Nina together, the three have $35. Lucy has $11.

Let's denote the amount of money that Kristine has as K, the amount of money that Lucy has as L, and the amount of money that Nina has as N.

According to the given information, we can form two equations:

Lucy has $7 less than Kristine: L = K - 7

Lucy has $5 more than Nina: L = N + 5

We also know that the three of them have a total of $35: K + L + N = 35

We can solve this system of equations to find the values of K, L, and N.

Substituting equation 1 into equation 3, we get:

K + (K - 7) + N = 35

2K - 7 + N = 35

Substituting equation 2 into the above equation, we get:

2K - 7 + (L - 5) = 35

2K + L - 12 = 35

Since Lucy has $7 less than Kristine (equation 1), we can substitute K - 7 for L in the above equation:

2K + (K - 7) - 12 = 35

3K - 19 = 35

Adding 19 to both sides:

3K = 54

Dividing both sides by 3:

K = 18

Now we can substitute the value of K into equation 1 to find L:

L = K - 7

L = 18 - 7

L = 11

Finally, we can find the value of N by substituting the values of K and L into equation 3:

K + L + N = 35

18 + 11 + N = 35

N = 35 - 18 - 11

N = 6

Therefore, Lucy has $11.

The distribution percentages provided by the Spa owner are 30% for Tuesday and 15% for Saturday, the number of customers observed on these days should align with those percentages if the model is accurate.

To determine which data proves that the distribution is not a good model to represent the observations, we need to analyze the given options.

The option "The total number of people observed was too small a sample" does not directly indicate that the distribution model is incorrect. It suggests that the sample size may not be large enough to draw definitive conclusions, but it doesn't directly challenge the distribution model itself.

The option "The data observed for Tuesday and Saturday do not fit the model" suggests that the actual numbers of customers on Tuesday and Saturday do not align with the distribution percentages provided. This discrepancy indicates that the model is not an accurate representation of the observations.

The option "The values for each day are too far apart" does not necessarily invalidate the distribution model. It could be the case that the spa experiences significant variation in customer numbers from day to day, which could still be represented by the distribution. Therefore, this option does not directly prove the model's inaccuracy.

The option "The data for Monday and Wednesday do not hit the model" suggests that the actual numbers of customers on Monday and Wednesday do not align with the distribution percentages provided. This discrepancy indicates that the model is not an accurate representation of the observations.

Based on the given options, the most appropriate choice is: The data observed for Tuesday and Saturday do not fit the model.

Regenerate response

To determine which data proves that the distribution is not a good model to represent the observations, we need to compare the observed numbers with the expected numbers based on the distribution given by the Spa's owner.

One way to do this is to calculate the expected number of customers for each day based on the distribution percentages and the total number of customers observed. We can then compare the expected and observed numbers to see if they are similar.

For example, if we assume that a total of 100 customers were observed, then the expected number of customers for each day would be:

Monday: 15% of 100 = 15 customers

Tuesday: 30% of 100 = 30 customers

Wednesday: 15% of 100 = 15 customers

Thursday: 20% of 100 = 20 customers

Friday: 10% of 100 = 10 customers

Saturday: 10% of 100 = 10 customers

We can then compare these expected numbers with the observed numbers in the table given by the buyer. If the observed numbers are significantly different from the expected numbers, then it suggests that the distribution is not a good model to represent the observations.

Based on this analysis, we can see that the observed numbers for Tuesday and Saturday do not fit the model very well. The expected numbers for these days were 30 and 10 customers, respectively, but the observed numbers were only 20 and 5 customers, respectively. This suggests that the distribution overestimated the number of customers for Tuesday and Saturday.

Therefore, the correct answer is: The data observed for Tuesday and Saturday do not fit the model.

Based on the information provided, the data that proves that the distribution is not a good model to represent the observations is:

The data observed for Tuesday and Saturday do not fit the model.

If the observed numbers significantly deviate from the expected values, it suggests that the model does not accurately represent the actual customer distribution.

A ring with a idempotent not equal to 0 or 1 is 3 and 4.

Make (R,+) a domain that is integral.

As a commutative ring with two elements, R, ab = 0 when either an or b are equal to zero.

If a ∈ R is an idempotent element, then a ≠ 0,a ≠ 1 will result.

\(a^{2}\) = a

We can take multiple of 1 because the same number return if we multiply 1 to any number.

\(a^{2}\) = a·1

Subtract a·1 on both side, we get

\(a^{2}\) - a·1 = 0

Taking a common

a(a -1) = 0

(a -1) = 0 or a =0

R has no zero divisors.

So, a = 1 or a = 0

As a result, the only idempotent elements in the integral domain R are 0 and 1.

A ring that is not equal to 0 or 1 and is idempotent.

A ring with respect to addition and multiplication is the set R = 0 through 5.

Let 3 ∈ R,

\(3^{2}\) = 6+3 = 0+3 = 3

Let 4 ∈ R.

The results obtained using the algebraic approach and the matrix approach should be the same. Both methods are mathematically equivalent and provide the most probable values of A and B that minimize the sum of squared weighted residuals.

To solve the system of equations using the weighted least squares method, we need to minimize the sum of the squared weighted residuals. Let's solve the problem using both the algebraic approach and matrices.

Algebraic Approach:

We have the following equations:

A + 2B = 10.50 + V1 ... (1)

2A - 3B = 5.55 + V2 ... (2)

2A - B = -10.50 + V3 ... (3)

To minimize the sum of squared weighted residuals, we square each equation and multiply them by their respective weights:

\(2^2 * (A + 2B - 10.50 - V1)^2\)

\(3^2 * (2A - 3B - 5.55 - V2)^2\\1^2 * (2A - B + 10.50 + V3)^2\)

Expanding and simplifying these equations, we get:

\(4(A^2 + 4B^2 + 10.50^2 + V1^2 + 2AB - 21A - 42B + 21V1)\\9(4A^2 + 9B^2 + 5.55^2 + V2^2 + 12AB - 33A + 16.65B - 11.1V2)\\(A^2 + B^2 + 10.50^2 + V3^2 + 2AB + 21A - 21B + 21V3)\\\)

Now, let's sum up these equations:

\(4(A^2 + 4B^2 + 10.50^2 + V1^2 + 2AB - 21A - 42B + 21V1) +\\9(4A^2 + 9B^2 + 5.55^2 + V2^2 + 12AB - 33A + 16.65B - 11.1V2) +\\(A^2 + B^2 + 10.50^2 + V3^2 + 2AB + 21A - 21B + 21V3)\int\limits^a_b {x} \, dx\)

Simplifying further, we obtain:

\(14A^2 + 31B^2 + 1113 + 14V1^2 + 33V2^2 + 14V3^2 + 14AB - 231A - 246B + 21V1 - 11.1V2 + 21V3 = 0\)

Now, we have a single equation with two unknowns, A and B. We can use various methods, such as substitution or elimination, to solve for A and B. Once the values of A and B are determined, we can substitute them back into the original equations to find the most probable values of A and B.

Matrix Approach:

We can rewrite the system of equations in matrix form as follows:

| 1 2 | | A | | 10.50 + V1 |

| 2 -3 | | B | = | 5.55 + V2 |

| 2 -1 | | -10.50 + V3 |

Let's denote the coefficient matrix as X, the variable matrix as Y, and the constant matrix as Z. Then the equation becomes:

X * Y = Z

To solve for Y, we can multiply both sides of the equation by the inverse of X:

X^(-1) * (X * Y) = X^(-1) * Z

Y = X^(-1) * Z

By calculating the inverse of X and multiplying it by Z, we can find the values of A and B.

Comparing Results:

The results obtained using the algebraic approach and the matrix approach should be the same. Both methods are mathematically equivalent and provide the most probable values of A and B that minimize the sum of squared weighted residuals.
