John initially had Php 132 and Mary initially had Php 252 (384 - 132).

Let's start by setting up the equations to solve for this problem.

Let x be the amount of money John had initially.

Then, Mary had (384 - x) initially.

After John gave Php 36 to Mary, John had (x - 36) left and Mary had (384 - x + 36) = (420 - x).

We are told that Mary had three times as much money as John after this transaction, so we can write:

3(x - 36) = 420 - x

Simplifying this equation gives:

3x - 108 = 420 - x

4x = 528

x = 132

Therefore, John initially had Php 132 and Mary initially had Php 252 (384 - 132).

Step-by-step explanation:

If Yasmin is the youngest of three siblings who ages are consecutive integers then Yasmin's age is 18, option B is correct.

Let's assume Yasmin's age is represented by the variable "Y".

Yasmin is the youngest, so her age is the smallest integer among the three siblings' ages.

Since their ages are consecutive integers, we can represent the ages of the three siblings as Y, Y+1, and Y+2.

According to the given information, the sum of their ages is 57.

So we can write the equation:

Y + (Y+1) + (Y+2) = 57

Now, let's solve for Y:

3Y + 3 = 57

Subtract 3 from both sides:

3Y = 54

Divide both sides by 3:

Y = 18

So, Yasmin's age (Y) is 18 years old. Option B is correct.

The book is opened to pages 11 and 12.

How to get the product of the page

x * (x + 1) = 132

Expanding the equation, we get:

x² + x = 132

To solve for x, we need to rewrite the equation as a quadratic equation:

x²+ x - 132 = 0

Now, we can factor the quadratic equation:

(x - 11)(x + 12) = 0

This equation has two solutions for x:

x = 11

x = -12

Since page numbers cannot be negative, we discard the second solution. Thus, the left-hand page number is 11, and the right-hand page number is 11 + 1 = 12.

The theorem that states F is a Fibonacci number if and only if either 5 F2+4 or 5 F2−4 is a perfect square was tested for FNs 8 and 13. However, the theorem was not valid for either of these numbers.

We know that a sequence of numbers is called a Fibonacci series if the next number in the sequence is the sum of the two previous ones.

The first two numbers of the Fibonacci series are 0 and 1.

Hence, the third number is 0 + 1 = 1,

fourth number is 1 + 1 = 2,

fifth number is 1 + 2 = 3, and so on.

Let's test this theorem for the FNs (a) 8 and (b) 13.

We have to verify whether either 5 F^{2}+4  or 5 F^{2}-4  is a perfect square.

For FN = 8,

5F^{2}+4 = 5(8)^2+4 = 324 and 5 F^{2}-4 = 5(8)^2-4 = 316.

Neither of these is a perfect square.

Hence, the theorem is not valid for FN = 8.

For FN = 13,5

F^{2}+4 = 5(13)2+4 = 876 and 5 F^{2}-4 = 5(13)2-4 = 860.

Neither of these is a perfect square. Hence, the theorem is not valid for FN = 13.

Therefore, the theorem is not valid for FNs 8 and 13.

The theorem that states F is a Fibonacci number if and only if either 5 F2+4 or 5 F2−4 is a perfect square was tested for FNs 8 and 13. However, it was found that the theorem was not valid for either of these numbers.

Answer:

AC=3x+11

Step-by-step explanation:

ok so AC is Both AB AND BC combined

2x-2+x+13=AC

3x+11=AC

AC=3x+11

Answer:

(2x-2) + (x+13)=6x+2 (take the lengths of AB and BC added together, and put equal to the value of AC)

3x+11 =6x+2 (drop the parenthesis and combine like terms on the left side)

-3x +11 =2 (subtract 6x from both sides and then subtract 11 from both sides)

-3x = -9 (divide both sides by -3 to find what x is)

x=3 (take the x value and plug it into the expression to find the length of AC)

6(3)+2 (multiply)

18+2 (add)

Answer:

y = 2/5x - 3

Step-by-step explanation:

First, we have to know what the slope is. Being perpendicular to -5/2, the slope becomes 2/5.

Then, you substitute the slope and given point into the equation to find the y-intercept.

y = 2/5x + b

(-5) = 2/5(-5) + b

(-5) = (-2) + b

b = -3

So, the equation is

y = 2/5x - 3

The equation of the line perpendicular to y = -5/2x + 1 that passes through the point (-5, -5) is y = 2/5x - 3.

We have the Equation,

y= -5/2x + 1

Here, the slope is -5/2.

Since perpendicular line have negative reciprocal of the slope of the given line.

So, the slope of the line perpendicular is 2/5.

Using point-slope form of the equation to find the equation of the perpendicular line.

The point-slope form is given by:

y - y1 = m(x - x1)

Using the point (-5, -5) and the slope 2/5,

y - (-5) = 2/5(x - (-5))

y + 5 = 2/5(x + 5)

y + 5 = 2/5x + 2

y = 2/5x - 3

Therefore, the equation of the line perpendicular to y = -5/2x + 1 that passes through the point (-5, -5) is y = 2/5x - 3.

The arc for the following circle is arc YZ that is option D.

In geometry, an arc is a part of a circle's circumference. It is defined as the portion of the circle that is contained between any two points on the circle. The length of an arc is proportional to the measure of its central angle, which is the angle formed by the two radii drawn to the endpoints of the arc. The measure of an arc is typically expressed in degrees, and it can be calculated using the formula:

arc length = (central angle measure / 360 degrees) x (circumference of the circle)

The null hypothesis is: null is 1.32
The alternative hypothesis is: null is greater than 1.32
The test statistic is: a. 4.065
The critical value is: a. qt(p=0.975, df=49) = 2.009

In this scenario, the null hypothesis (H0) is that the average number of people an infected child infects is equal to the average number of people an infected adult infects, which is 1.32. The alternative hypothesis (H1) is that an infected child infects more people than an infected adult, so the average is greater than 1.32.

To calculate the test statistic, we use the t-test formula: (sample mean - population mean) / (sample standard deviation / sqrt(sample size)). In this case, it would be (1.55 - 1.32) / (0.8 / sqrt(50)), resulting in a test statistic of 4.065.

To find the critical value, we use the t-distribution table with a significance level of 0.05 and degrees of freedom equal to the sample size minus 1 (50 - 1 = 49). The critical value is found by looking up the value of qt(p=0.975, df=49), which is 2.009.

Since the test statistic (4.065) is greater than the critical value (2.009), we reject the null hypothesis in favor of the alternative hypothesis. This means that there is significant evidence to suggest that, on average, an infected child in school infects more people than an infected working adult does.

It will take 2.2 hours for the two trains to meet.

We can find the time taken by the two trains to meet by using the formula,

large Time=Distance/Speed

Let's consider the time taken by the two trains to meet be "t".The distance between two trains = 418 miles.

Now, the first train is traveling at a speed of 85 mph and the second train is traveling at a speed of 105 mph.

Let's calculate the distance covered by both the trains in time "t".The distance covered by the first train in time "t"=85t.

The distance covered by the second train in time "t"=105t.

So, the total distance covered by both the trains in time "t" is,

Distance covered = 85t+105t=190t.

But we know the distance between the two trains is 418 miles.

Therefore,190t = 418

Now, solve for "t"t = 418/190t = 2.2 hours

Therefore, the two trains will meet in 2.2 hours.

The process described above satisfies the Markov property because the future state of the system only depends on the current state, and not on any previous states. The transition probability matrix is P =\(\left[\begin{array}{cccc}0&1&0&0\\1/2&0&1/2&0\\0&1/2&0&1/2\\0&0&1&0\end{array}\right]\)  

In other words, given the current state, the probability distribution of the next state depends only on the current state and not on any previous history.

Let Xn denote the state of the system after the nth step, where Xn = i means that the first urn contains i white balls and 3-i black balls. Since each step involves drawing one ball from each urn and switching them, the number of white balls in the first urn can only change by one after each step. Thus, the only possible transitions are:

If Xn = 0, then the next state Xn+1 can only be 1, with probability 1, since there is only one white ball in the first urn.

If Xn = 1, then the next state Xn+1 can be either 0 or 2, each with probability 1/2, since there are two white balls in the first urn and each ball is equally likely to be drawn.

If Xn = 2, then the next state Xn+1 can be either 1 or 3, each with probability 1/2, since there are two black balls in the first urn and each ball is equally likely to be drawn.

If Xn = 3, then the next state Xn+1 can only be 2, with probability 1, since there is only one black ball in the first urn.

Therefore, the transition probability matrix is:

P =\(\left[\begin{array}{cccc}0&1&0&0\\1/2&0&1/2&0\\0&1/2&0&1/2\\0&0&1&0\end{array}\right]\)  

where Pij is the probability of transitioning from state i to state j. For example, P12 = 1/2 means that the probability of transitioning from state 1 (one white ball in the first urn) to state 2 (two white balls in the first urn) is 1/2.

Correct Question :

Three white balls and three black balls are distributed in two urns in such a way that each contain three balls. We say that the system is in state i, i=0,1,2,3, if the first urn contains i white balls. At each step, we draw one ball from each urn and place the ball drawn from the first urn into the second, and conversely with the ball from the second urn. Let Xn denote the state of the system after the nth step. Explain why Xn = 0, 1, 2, ......... is a Markov chain and calculate its transition probability matrix.
