Answer:

The difference of the time taken for each of the two journeys is given as follows;

The difference of time = 2000/(x·(x + 10))

Step-by-step explanation:

The speed with which the car completes the 200 km journey = x km/h

The speed with which the car completes the return journey = (x + 10) km/h

Let t₁ represent the time it takes the car to complete the 200 km and let t₂ represent the time it takes the car to complete the return journey, we have;

t₁ = 200/(x)

t₂ = 200/(x + 10)

The difference of the time taken for each of the two journeys = t₁ - t₂

We have;

t₁ - t₂ = 200/(x) - 200/(x + 10)

200/(x) - 200/(x + 10)  = (200·(x + 10) - 200·x)/((x)·(x + 10)) = 2000/((x)·(x + 10))

∴ t₁ - t₂ = 2000/((x)·(x + 10)) = 2000/(x·(x + 10))

The difference of the time taken for each of the two journeys = t₁ - t₂ = 2000/(x·(x + 10))

Using the given data on the number of live multiple-delivery births for women aged 15 to 54, we need to calculate probabilities related to the age groups of the mothers. The probability of a randomly selected multiple birth involving a mother aged 30 to 39 will be determined, as well as the probabilities of not being in the age range, being less than 45, and being at least 40. Finally, we need to interpret whether a multiple birth involving a mother aged at least 40 is unusual.

(a) To calculate the probability of a randomly selected multiple birth involving a mother aged 30 to 39, we sum the number of multiple births in that age group and divide it by the total number of multiple births for women aged 15 to 54.

P(30 to 39) = 2822 / (89 + 508 + 1631 + 2822 + 1855 + 374 + 119)

(b) To find the probability of a randomly selected multiple birth involving a mother who is not aged 30 to 39, we subtract the probability found in part (a) from 1.

P(not 30 to 39) = 1 - P(30 to 39)

(c) To determine the probability of a randomly selected multiple birth involving a mother aged less than 45, we sum the number of multiple births for age groups below 45 and divide it by the total number of multiple births for women aged 15 to 54.

P(less than 45) = (89 + 508 + 1631 + 2822 + 1855 + 374) / (89 + 508 + 1631 + 2822 + 1855 + 374 + 119)

(d) To find the probability of a randomly selected multiple birth involving a mother aged at least 40, we sum the number of multiple births for age groups 40-44 and 45-54, and divide it by the total number of multiple births for women aged 15 to 54.

P(at least 40) = (374 + 119) / (89 + 508 + 1631 + 2822 + 1855 + 374 + 119)

Interpretation: The answer to part (d) will determine whether a multiple birth involving a mother aged at least 40 is unusual. If the probability is less than 0.05, it can be considered unusual. Therefore, we need to compare the calculated probability to 0.05 and select the correct choice.

Answer:

a = 36, b = 54

Step-by-step explanation:

Since the terms are in arithmetic progression then there is a common difference d between consecutive terms , that is

b - a = 72 - b ( add b to both sides )

2b - a = 72 → (1)

and

a + b - 72 = b - a ( subtract b - a from both sides )

2a - 72 = 0 ( add 72 to both sides )

2a = 72 ( divide both sides by 2 )

a = 36

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

Substitute a = 36 into (1) and evaluate for b

2b - 36 = 72 ( add 36 to both sides )

2b = 108 ( divide both sides by 2 )

b = 54

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

Thus a = 36 and b = 54

The sequence is therefore 36, 54, 72, 90 , .....

Answer:

a= 36

b= 54

Step-by-step explanation:

formula for AP is nth term= a+(n-1)d

3rd term=> a+2d=72

2nd term=> a+d=b

Comparing the two equations:

2d-d=72-b

d=72-b

4th term=> a+3d=a+b

d= 72-b

a+3(72-b)=a+b

a+216-3b=a+b

216-3b=b

216=4b

b=54

d=72-b

d=72-54

d=18

a+d= b

a=b-d

a=54-18

Answer: D (12.42, 18.09)

Explanation:

For A, if you substitute them, 6.15+2.41(x because x always is first), you get 8.56 but y is 8.56. So therefore, A is wrong cause it is a solution but it asks us for an incorrect solution.

For B, if you substitute the numbers, 6.09+6.15 = 12.24 but y is 12.24 meaning 12.24 = 12.24 which is true. But the question asks us which is not true/a solution, so therefore, B is also wrong.

For C, if you substitute the numbers, you get 9.72+6.15 which is 15.87. Since y is 15.87, the substituted question is 15.87=15.87 which is true and therefore, C is also wrong since it is true but it is asking us for an incorrect solution.

We are then left with D, which is the correct option. I'm guessing you want an explanation for why it is correct. So if you substitute the numbers, you would get y = 12.42+6.15 and 12.42+6.15 is 18.57 but y is 18.09. So the equation is 18.09 = 18.57 which doesn't make sense and is false. Thus, D is the correct answer because it provides a set of numbers that is a false solution to the equation.

REMEMBER:

In an ordered pair, x is the first number while y is the second, so make sure you substitute correctly!

To subtract 5xy + 6x^2 - 8y^2 from 9x^2 - 10xy - 5y^2 + 4, we need to combine like terms.

First, let's distribute the negative sign to each term in 5xy + 6x^2 - 8y^2 to get:

-5xy - 6x^2 + 8y^2

Now we can group the like terms together and subtract them from the other expression:

(9x^2 - 10xy - 5y^2 + 4) - (5xy + 6x^2 - 8y^2)

= 9x^2 - 10xy - 5y^2 + 4 - 5xy - 6x^2 + 8y^2

= (9x^2 - 6x^2) + (-10xy - 5xy) + (-5y^2 + 8y^2) + 4

= 3x^2 - 15xy + 3y^2 + 4

Therefore, the result of subtracting 5xy + 6x^2 - 8y^2 from 9x^2 - 10xy - 5y^2 + 4 is 3x^2 - 15xy + 3y^2 + 4.

Answer:

3x^2 - 15xy + 3y^2 + 4

Step-by-step explanation:

To subtract 5xy + 6x^2 - 8y^2 from 9x^2 - 10xy - 5y^2 + 4, we can combine like terms:

9x^2 - 10xy - 5y^2 + 4 - (5xy + 6x^2 - 8y^2)

Simplifying the expression inside the parentheses:

= 9x^2 - 10xy - 5y^2 + 4 - 5xy - 6x^2 + 8y^2

Combining like terms again:

= (9x^2 - 6x^2) + (-10xy - 5xy) + (-5y^2 + 8y^2) + 4

= 3x^2 - 15xy + 3y^2 + 4

Therefore, the result of subtracting 5xy + 6x^2 - 8y^2 from 9x^2 - 10xy - 5y^2 + 4 is 3x^2 - 15xy + 3y^2 + 4.

The population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).

To determine whether the population proportion who participated in voting or the sample proportion from the survey is higher, we need to compare the percentages.

The population proportion who participated in voting is given as 63% of all registered voters.

This means that out of every 100 registered voters, 63 participated in voting.

In the survey of retired voters, 162 out of 275 participants voted. To calculate the sample proportion, we divide the number of retired voters who participated (162) by the total number of retired voters in the sample (275) and multiply by 100 to get a percentage.

Sample proportion = (162 / 275) \(\times\) 100 ≈ 58.91%, .

Comparing the population proportion (63%) with the sample proportion (58.91%), we can see that the population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).

Therefore, based on the given data, the population proportion who participated in voting is higher than the sample proportion from this survey.

It's important to note that the sample proportion is an estimate based on the surveyed retired voters and may not perfectly represent the entire population of registered voters.

To find the general solutions of the given differential equations using D-operator methods, we will use the fact that D-operator (D) represents differentiation with respect to x.

3.1 For the differential equation (D² - 5D + 6)y = e^(-x) + sin(2x), we can factorize the characteristic equation as (D - 2)(D - 3)y = e^(-x) + sin(2x). Solving each factor separately, we have: (D - 2)y = e^(-x) => y₁ = Ae^(2x) + e^(-x) (where A is a constant). (D - 3)y = sin(2x) => y₂ = Bsin(2x) + Ccos(2x) (where B and C are constants). The general solution is y(x) = y₁ + y₂ = Ae^(2x) + e^(-x) + Bsin(2x) + Ccos(2x).

3.2 For the differential equation (D² + 2D + 4)y = e^(2x)sin(2x), the characteristic equation is (D + 2i)(D - 2i)y = e^(2x)sin(2x). Solving each factor separately, we have: (D + 2i)y = e^(2x)sin(2x) => y₁ = Ae^(-2ix)e^(2x)sin(2x) = Ae^(2x)sin(2x)

(D - 2i)y = e^(2x)sin(2x) => y₂ = Be^(2ix)e^(2x)sin(2x) = Be^(2x)sin(2x)

The general solution for the first differential equation is y(x) = Ae^(2x) + e^(-x) + Bsin(2x) + Ccos(2x), and the general solution for the second differential equation is y(x) = Ae^(2x)sin(2x) + Be^(2x)sin(2x), where A, B, and C are constants.

What you need to do is count the number of squares or slices it has and then count how Buchanan the chunk is divided into, should be 6

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

Explanation:

Ignore the dashed smaller lines for now. The solid black vertical lines form 4 smaller equal pieces, and not 5. Each tickmark represents 1/4 and not 1/5

So if you wanted to represent a model for \(\frac{1}{4}\div 6\), then you would use the lower left corner. However, we want that 1/4 to be 1/5 instead. So this is why the answer is the lower left corner.

Everything else is a correct model. We started dividing everything into 5 equal parts. Then we focused on one of those slices, and subdivided that slice into 6 equal parts. Imagine doing that for each slice and we should have 5*6 = 30 smaller pieces total. Hence \(\frac{1}{5} \div 6 = \frac{1}{5} \times \frac{1}{6} = \frac{1}{30}\)

C. The image shows two right triangles with one pair of congruent leg and congruent hypotenuse. Therefore, the congruence is HL.

D. This shows two right triangles that share one side (a leg) and have the other leg also congruent to each other. Therefore, their congruence is LL and SAS (leg, right angle, leg).

E. This shows two triangles with a pair of congruent sides, a pair of congruent angles, and they have a common side, therefore congruent since they are the same.

So, their congruence is SAS.

F. This shows two right triangles sharing the same hypotenuse, and with a pair of congruent angles. Therefore, their congruence is HA.

G. This shows two right triangles with congruent hypotenuses, one congruent pair of legs, and two congruent pairs of angles (if we include the right angle).

So, their congruence is HA and HL.

H. The two triangles here have a right angle, a pair of congruent sides, and a pair of angles that are opposite by vertex, so they are also congruent angles.

Therefore, their congruence is ASA.

If two square matrices of order n, namely a and b, have the same determinant (det(a) = det(b)), then the determinant of their product ab, denoted as det(ab), is equal to the determinant of the square of matrix a, denoted as det(a²).

The determinant of a matrix is a scalar value that can be computed using various methods, such as cofactor expansion or row reduction. The determinant of a product of two matrices is equal to the product of their determinants, i.e., det(ab) = det(a) × det(b).

Given that det(a) = det(b), we can substitute this equality into the determinant of the product of a and b, i.e., det(ab) = det(a) × det(b).

Since we are trying to prove that det(ab) = det(a²), we need to find the determinant of a². The square of a matrix a, denoted as a², is the product of matrix a with itself, i.e., a² = a × a.

Using the determinant property for the product of two matrices, we have det(a²) = det(a) × det(a).

Now, substituting det(a) = det(b) into the equation for det(a²), we get det(a²) = det(a) × det(a) = det(a) × det(b).

Comparing this with the earlier equation for det(ab), we see that det(ab) = det(a²), as both equations are equal.

Therefore, we can conclude that if a and b are square matrices of order n, and det(a) = det(b), then the determinant of their product ab, denoted as det(ab), is equal to the determinant of the square of matrix a, denoted as det(a²).

a) When x₃ = 0, a solution can be expressed as (-1 + 3x₄, 4 - 2x₄, 0, x₄), where x₄ is any real number.

b) When x₃ = 0, there are infinitely many solutions because x₄ can take any real value, leading to different solutions.

c) When x₃ = 1 and x₄ = -1, a solution is (-6, 7, 1, -1).

d) When x₃ = 1 and x₄ = -1, there is only one solution because both x₃ and x₄ are fixed to specific values.

Here, we have,

(a) When x₃ = 0, we can substitute this value into the given solution set:

x₁ = -1 - 2(0) + 3x₄ = -1 + 3x₄

x₂ = 4 + (0) - 2x₄ = 4 - 2x₄

x₃ = 0

x₄ = x₄

So, when x₃ = 0, a solution can be expressed as (-1 + 3x₄, 4 - 2x₄, 0, x₄), where x₄ is any real number.

(b) When x₃ = 0, there are infinitely many solutions because x₄ can take any real value, leading to different solutions.

(c) When x₃ = 1 and x₄ = -1, we can substitute these values into the given solution set:

x₁ = -1 - 2(1) + 3(-1) = -1 - 2 - 3 = -6

x₂ = 4 + (1) - 2(-1) = 4 + 1 + 2 = 7

x₃ = 1

x₄ = -1

So, when x₃ = 1 and x₄ = -1, a solution is (-6, 7, 1, -1).

(d) When x₃ = 1 and x₄ = -1, there is only one solution because both x₃ and x₄ are fixed to specific values.
