given three consecutive odd integers their sum is two times third number plus 25 what are the three numbers

Answers

The three consecutive odd integers are 27, 29, and 31.

Given that three consecutive odd integers their sum is two times third number plus 25

Let's call the first odd integer "x." Since the integers are consecutive odd numbers, therefore, the next two odd integers would be x+2 and x+4.

Now according to the problem, their sum is equal to two times the third number (x+4) plus 25:

x + (x+2) + (x+4) = 2(x+4) + 25

Simplifying the left side:

3x + 6 = 2x + 8 + 25

Next combining like terms:

3x + 6 = 2x + 33

Subtracting 2x and 6 from both sides:

x = 27

Therefore, the three consecutive odd integers are 27, 29, and 31.

Solve the initial boundary value problem ut = 2uxx for x ∈ (-π, π], t ∈ [0, + [infinity]), ux(0, t) = ux,(1,t) = 0, for t ∈ [0, + [infinity]), u(x,0) = π^2 – π^2 for r ∈ [ -π, π]

Answers

The solution to the initial boundary value problem is u(x,t) = 1/π.

To solve the initial boundary value problem ut = 2uxx for x ∈ (-π, π], t ∈ [0, + [infinity]), ux(0, t) = ux,(1,t) = 0, for t ∈ [0, + [infinity]), u(x,0) = π^2 – π^2 for r ∈ [ -π, π], we can use the method of separation of variables.

Assume u(x,t) = X(x)T(t), then we have:

X''(x) + λX(x) = 0, T'(t) + 2λT(t) = 0

where λ is a separation constant. The general solution for the spatial equation is X(x) = A sin(nx) + B cos(nx), where n = sqrt(λ) and A, B are constants. Since u(0,t) = u(1,t) = 0, we have A = 0 and B cos(nπ) = 0, which implies n = kπ for k = 1, 2, 3, ... Thus, the spatial eigenfunctions are X_k(x) = cos(kπx), and the corresponding eigenvalues are λ_k = -(kπ)^2.

The time equation can be solved as T(t) = Ce^(-2λ_k t), where C is a constant. Therefore, the general solution for the initial boundary value problem is:

u(x,t) = Σ C_k cos(kπx) e^(-2(kπ)^2 t)

where the sum is taken over all k = 1, 2, 3, .... To determine the constants C_k, we use the initial condition u(x,0) = π^2 – π^2 = 0. This gives:

Σ C_k cos(kπx) = 0

Since the eigenfunctions form an orthogonal set on [-π, π], we can multiply both sides by cos(mπx) and integrate over [-π, π] to obtain:

C_m = 0 for m = 1, 2, 3, ...

Thus, the only non-zero constant is C_0, which can be determined using the normalization condition:

1 = ∫_(-π)^π (u(x,t))^2 dx = C_0^2 π^2

Therefore, C_0 = 1/π. Thus, the solution to the initial boundary value problem is:

u(x,t) = (1/π) cos(0πx) e^(-2(0π)^2 t) = 1/π e^0 = 1/π

In conclusion, the solution to the initial boundary value problem is u(x,t) = 1/π.

If the tournament has n contestants, where n is a power of 2, find and solve a recurrence relation for the total prize money in the tournament

Answers

The recurrence relation for the total prize money in the tournament is T(n) = 2T(n/2) + 100n, under the condition that tournament has n contestants, where n is a power of 2.



Let's us consider there are n players in the tournament where n is a power of 2. Each player wins k hundreds of dollars, where k is the number of people in the sub-tournament won by the player.

Let us present T(n) as the total prize money in a tournament with n players. We observe that  T(1) = 100 since there is only one player who loses in the first round and gets $100.

For n > 1, we can divide the tournament into two sub-tournaments each with n/2 players. Let's denote k as the number of people in a sub-tournament won by a player. Then we can see that k = n/2 for each player since each player wins one of two sub-tournaments.

Therefore, each player wins k hundreds of dollars where k = n/2. The total prize money for each sub-tournament is T(n/2). Therefore, we can write:

T(n) = 2T(n/2) + 100n

Answers

If random sample of 1000 applicants, 392 applicants were accepted, then (c) interval is from 36.2% to 42.2%. Since value of 42% lies in interval, Bridgeton's claimed acceptance rate is accurate.

The "Confidence-Interval" is defined as "range-of-values" which contain the "true-value" of a population parameter with a certain probability.

To calculate the 95% confidence interval, we use the formula:

⇒ CI = p ± z × √((p(1-p))/n),

where : p = sample proportion (accepted applicants / total applicants)

⇒ z is = z-score associated with desired "level-of-confidence" (95% corresponds to z = 1.96)

⇒ n is = sample size = (1,000),

First, we calculate the "sample-proportion" (p) :

⇒ p = 392 / 1000 = 0.392,

Substituting the values,

We get,

⇒ CI = 0.392 ± 1.96 × √((0.392(1-0.392))/1000),

⇒ 0.392 ± 0.030,

So, the 95% confidence interval for the proportion of accepted applicants at Bridgeton University is (0.362, 0.422) = 36.2% to 42.2%.

Next, To evaluate whether Bridgeton's claim of accepting 42% of applicants seems accurate, we can check if the claim falls within the confidence interval.

The claim of 42% falls within the 95% confidence interval of (0.362, 0.422). So, acceptance rate claimed by Bridgeton is accurate.

Therefore, the correct option is (c).

Let B {bı, b2} and C = {c1, c2} be bases for R^2 where bı [-1;8]. b2 [1;-5], c1 = [1;4]. Find the change-of-coordinates matrix from B to C and the change-of-coordinates matrix from C to B.

In the given problem, we have the bases B and C as follows:

B = {b1, b2} where b1 = [-1;8] and b2 = [1;-5]

C = {c1, c2} where c1 = [1;4] and c2 = [0;1]

We need to find the change-of-coordinates matrix from B to C and from C to B.

To find the change-of-coordinates matrix from B to C, we need to express the basis vectors of B in terms of the basis vectors of C. We can do this by solving the following equations:

b1 = x1c1 + y1c2

b2 = x2c1 + y2c2

where x1 , y1, x2, and y2 are the coefficients we want to find.

Substituting the given values, we get:

[-1;8] = x1*[1;4] + y1*[0;1]

[1;-5] = x2*[1;4] + y2*[0;1]

Solving these equations, we get:

x1 = -17/4, y1 = 1/4, x2 = 9/4, and y2 = -1/4

Therefore, the change-of-coordinates matrix from B to C is:

[-17/4  9/4]

[ 1/4 -1/4]

To find the change-of-coordinates matrix from C to B, we need to express the basis vectors of C in terms of the basis vectors of B. We can do this by solving the following equations:

Substituting the given values and solving these equations, we get:

a1 = 4/17, a2 = -1/17, b1 = -1/17, and b2 = -5/17

Therefore, the change-of-coordinates matrix from C to B is:

Answers

This is the contrapositive of the original statement PQ -> P, which allows us to conclude that the argument is valid.

The argument can be validated using the modus tollens rule of inference, also known as the law of contrapositive. This rule states that if we have a conditional statement of the form "If A, then B," and we know that B is false, we can infer that A must also be false.

In the given argument, we have two conditional statements:

(PA -> ST) -> ~(MV -> N) (premise)

PQ -> ~(MV -> N) (premise)

To use modus tollens, we start by assuming the negation of the conclusion we want to prove, which is P. Then, we use the second premise to infer that ~(MV -> N) must be true. Using the logical equivalence ~(p -> q) = p /\ ~q, we can rewrite this as MV /\ ~N.

Next, we can use the first premise to infer that if PA -> ST is true, then MV -> N must be false. Since we have already established that MV /\ ~N is true, we can conclude that PA -> ST must be false as well.

Finally, we use the second premise again to infer that PQ must be false. This is because if PQ were true, then ~(MV -> N) would also be true, which contradicts our previous conclusion.

Therefore, we have shown that if PQ is true, then P must be false. This is the contrapositive of the original statement PQ -> P, which allows us to conclude that the argument is valid.

(c) Outline one reason why the maxima observed at W, X and Y will have different intensities from each other:

Answers

(a)This is because the distance between the slits is such that the waves from S1 and S2 arrive at Y in phase, resulting in constructive interference and a maximum in intensity. (b) The frequency of microwaves is [tex]1.94x10^8 Hz[/tex]. (c)One reason why the maxima observed at W, X, and Y will have different intensities from each other is due to the phenomenon of diffraction.

(a) The pattern of intensity maxima and minima observed in the double-slit experiment can be explained by the principle of interference. The microwaves from S1 and S2 interfere with each other as they propagate through the slits and form a pattern on the screen where they are detected. When the receiver is initially placed at W, it is equidistant from both slits and therefore the path lengths for the waves from each slit are equal, resulting in constructive interference and a maximum in intensity.

As the receiver is moved towards Z, the path length from S1 to the receiver decreases while the path length from S2 to the receiver increases. At X, the path lengths from S1 and S2 differ by one wavelength, resulting in constructive interference and a maximum in intensity. At Y, the path lengths from S1 and S2 differ by half a wavelength, resulting in destructive interference and a minimum in intensity.

The distance from S1 to Y is 1.243m, which is equal to the wavelength of the microwaves, while the distance from S2 to Y is 1.181m, which is also equal to the wavelength of the microwaves. This is because the distance between the slits is such that the waves from S1 and S2 arrive at Y in phase, resulting in constructive interference and a maximum in intensity.

(b) The frequency of the microwaves can be determined using the equation for the wavelength of a wave, which is given by[tex]λ = c/f[/tex], where[tex]λ[/tex]is the wavelength, c is the speed of light, and f is the frequency. We know that the wavelength of the microwaves is 1.243m, so we can rearrange the equation to solve for the frequency: f =[tex]c/λ[/tex] = 2.41 ×[tex]10^8[/tex]m/s ÷ 1.243m =[tex]1.94x10^8 Hz[/tex].

(c) As the waves pass through the narrow slits, they spread out and interfere with each other, creating a diffraction pattern. The intensity of the pattern is determined by the amount of interference, which depends on the size of the slits and the wavelength of the waves.

The intensity of the maxima will be affected by the width of the slits, with narrower slits producing a more intense diffraction pattern. The intensity will also be affected by the distance from the slits to the screen, with further distances producing a less intense diffraction pattern. Therefore, the maxima observed at different points on the screen will have different intensities due to variations in the diffraction pattern.

The diagram shows a prism placed on a horizontal floor. The prism has a height of 5m and a volume of 30m cubed. The pressure on the floor due to to the prism is 55 newtons/m². Work out the force exerted by the prism on the floor.

Answers

Step-by-step explanation:

We can start by using the formula:

force = pressure x area

The pressure on the floor is given as 55 newtons/m². To find the area, we need to first calculate the base of the prism. We can do this by rearranging the formula for volume:

volume = base x height x depth

30 = base x 5 x depth

base = 6m² (dividing both sides by 5 x depth)

Now we can calculate the force exerted by the prism on the floor:

force = pressure x area

force = 55 x 6

force = 330 newtons

Therefore, the force exerted by the prism on the floor is 330 newtons.

If I have just arrived at the downtown bus stop, how long, on the average, should I expect to wail for a bus?

Answers

If you have just arrived at the downtown bus stop, you should expect to wait about 26 minutes for a bus to arrive.

To calculate the expected waiting time, we need to find the weighted average of the waiting times for each interval, where the weights are the probabilities of each interval occurring.

Let t1, t2, and t3 be the waiting times for intervals of 20 minutes, 40 minutes, and 2 hours, respectively.

Then, we have:

t1 = 10 minutes (half the interval time)

t2 = 20 minutes (half the interval time)

t3 = 60 minutes (half the interval time)

The probabilities of each interval are 0.2, 0.4, and 0.4, respectively.

Therefore, the expected waiting time is:

E(waiting time) = 0.2 * t1 + 0.4 * t2 + 0.4 * t3

= 0.2 * 10 + 0.4 * 20 + 0.4 * 60

= 26 minutes

So, on average, you should expect to wait about 26 minutes for a bus to arrive.

A rental car company charges $20 per day to rent a car and $0.10 for every mile driven. Addison wants to rent a car, knowing that:

She plans to drive 100 miles.
She has at most $80 to spend.


Write and solve an inequality which can be used to determine xxx, the number of days Addison can afford to rent while staying within her budget.

Answers

Answer:

Let xxx be the number of days Addison can afford to rent.

The cost of renting the car for xxx days is 20*x.

The cost of driving 100 miles is 0.10*100 = 10.

The total cost of renting the car and driving is 20*x + 10.

Addison wants to spend at most $80, so we have the inequality 20*x + 10 <= 80.

Solving for xxx, we get x <= 3.

Therefore, Addison can afford to rent the car for at most 3 days.

What is 3 + 2 HELP then after add 3456 then subtract 45 and then divid 20

Answers

The simplify value of numeric expression, 3 + 2, after adding 3456 then subtracting 45 and then dividing by 20 is equals the 17.8.

We have an expression of numbers, 3 + 2 we have to apply some arithematic operations on it and determine the final simplfy value. Let the expression be x = 3 + 2, add 3456 in it

=> x = 3 + 2 + 3456

Substracts 45 from above expression

=> x = 3 + 2 + 3456 - 45

Dividing the above expression of x by 20

=>

[tex]\frac{ x } {20} = \frac{ 3 + 2 + 3456 - 45}{20}[/tex]

[tex]= \frac{3416}{20}[/tex]

= 17.8

Hence, required simplify value is 17.8.

The coordinates of points A and B are A(4, -2) and B(12, 10). What are the coordinates of the point that is of the way from A to B?
A (1,-0.5)
B. (6, 1)
C. (10,7)
D. (3,2.5)

Answers

Answer:

To find the point that is halfway between A(4, -2) and B(12, 10), we can find the average of the x-coordinates and the average of the y-coordinates.

average x-coordinate = (4 + 12)/2 = 8 average y-coordinate = (-2 + 10)/2 = 4

Therefore, the point that is halfway between A and B has the coordinates (8, 4), which is answer choice B.

find the median of the lower half
17,18,19,20,21,24,25,27

Answers

Answer:

18.5

Step-by-step explanation:

Make sure the numbers are in order from least to greatest!

To define the median of the lower half, you must first divide the data set in half. Then, find the median of the first half.

17, 18, 19, 20 | 21, 24, 25, 27

To find the median, locate the number(s) in the middle of the data set.

17, 18, 19, 20

There are two numbers in the middle: 18 and 19.

When you have two medians, add the numbers, then divide the sum by 2.

[tex]18+19=37\\37/2=18.5[/tex]

The median of the lower half is 18.5.

Answer:

7x + 33 = 10x

3x = 33, so x = 11

These congruent alternate interior angles measure 110°.

The value of x in the parallel line is 11.

How to find the angles in parallel lines?

When parallel line are crossed by a transversal line, angle relationships are formed such as corresponding angles, alternate exterior angles, alternate interior angles, same side interior angles, vertically opposite angles etc.

Therefore, let's find the value of x using the angle relationship.

Hence,

7x + 33 = 10x (alternate interior angles)

33 = 10x - 7x

3x = 33

divide both sides by 3

x = 33 / 3

Therefore,

x = 11

Which of the following charts is used when the measure for the sample is weight, volume, number of inches or other variable measurements? 1. Mean chart 2. Range chart 3. C chart 4. P chart

Answers

The chart that is typically used when the measure for a sample is weight, volume, number of inches or other variable measurements is the mean chart.

The mean chart is a statistical process control chart that plots the average or mean of the sample against the upper and lower control limits. This chart is useful when the process being measured produces continuous data that is normally distributed.
The range chart is used when the measure for the sample is the range of variation within the sample. This chart shows the difference between the largest and smallest values in the sample, and is useful for detecting changes in variability.

The C chart is used when the measure for the sample is the number of defects or occurrences within a given unit of measurement. This chart is useful for measuring the process capability of a system and identifying areas where improvements can be made.
Finally, the P chart is used when the measure for the sample is the proportion of defective items within a given sample. This chart is useful for measuring the quality of a product or process and identifying areas where defects are occurring.

Overall, the mean chart is the most commonly used chart for variable measurements, but the specific chart chosen will depend on the nature of the data being collected and the goals of the analysis.
To briefly explain each of the chart types:

1. Mean chart: Used for monitoring the central tendency of a variable over time.
2. Range chart: Used for monitoring the variability of a continuous variable, like weight, volume, or number of inches, over time.
3. C chart: Used for monitoring the number of defects in a unit of measure (e.g., per item or per batch) over time.
4. P chart: Used for monitoring the proportion of defective items in a sample over time.

In your case, since you are working with variable measurements like weight, volume, and the number of inches, the most appropriate chart to use is the Range chart (#2). This chart will help you monitor the variability of the measured data over time and allow you to analyze any patterns or trends that may emerge.

Mr. Wells always buys a big container of erasers before school starts each year. On the first day of school, he gives each of his students an eraser he has randomly chosen from the container. School started today, and so far he has handed out 3 blue, 5 yellow, 4 purple, 2 red, and 7 green erasers.
Based on the data, what is the probability that the next eraser Mr. Wells hands out will be blue?

Answers

Answer:

We can use the concept of probability to determine the likelihood of Mr. Wells handing out a blue eraser next.

The probability of an event happening is equal to the number of favorable outcomes divided by the total number of possible outcomes. In this case, the favorable outcome is Mr. Wells handing out a blue eraser, and the total number of possible outcomes is the total number of erasers in the container.

To find the total number of erasers in the container, we can add up the number of erasers in each color:

3 + 5 + 4 + 2 + 7 = 21

Therefore, there are 21 erasers in the container.

To find the number of blue erasers in the container, we need to use the information given in the problem. We know that Mr. Wells has already handed out 3 blue erasers, so there must be some blue erasers left in the container. However, we do not know how many blue erasers are left.

Since we do not have enough information to determine the exact number of blue erasers left, we can assume that all the remaining erasers in the container are equally likely to be handed out next. This is known as the principle of equally likely outcomes.

Therefore, the probability of Mr. Wells handing out a blue eraser next is equal to the number of blue erasers in the container divided by the total number of erasers in the container:

P(blue eraser) = number of blue erasers / total number of erasers

We do not know the exact number of blue erasers, but we know that there are some blue erasers left. Therefore, the probability of Mr. Wells handing out a blue eraser next is greater than zero.

So, the answer to the question is:

The probability that the next eraser Mr. Wells hands out will be blue is greater than zero, but we cannot determine the exact probability without knowing the number of blue erasers left in the container.

A person is assuming responsibility for a $335 000 loan which should be repaid in 15 equal repayments of Sa, the first one immediately and the following after each of the coming 14 years. Find a if the annual interest rate is 14%.

Answers

Value of a is $52,427.69

To find the value of "a" in this situation, we can use the formula for the present value of an annuity:

PV = a * [1 - (1 + r)^(-n)] / r

where PV is the present value of the loan, a is the amount of each payment, r is the annual interest rate (expressed as a decimal), and n is the number of payments.

In this case, we know that PV = $335,000, r = 0.14, and n = 15. We want to solve for a.

Substituting these values into the formula, we get:

$335,000 = a * [1 - (1 + 0.14)^(-15)] / 0.14

Simplifying, we get:

a = $52,427.69

Therefore, the person assuming responsibility for this loan would need to make 15 equal payments of $52,427.69 each year for the next 15 years in order to repay the loan. The total amount paid would be $786,415.35, which includes both the principal amount of $335,000 and $451,415.35 in interest.
